TSO and TBS cannot co-exist. TBS requires special descriptor to be allocated at bootup. Initialising Tx queues at probe to support TSO and TBS can help in allocating those resources at bootup. TX queues with TBS can support etf qdisc hw offload.

Kui-Feng Lee says: ==================== Remove expired routes with a separated list of routes. This patchset is resent due to previous reverting. [1] FIB6 GC walks trees of fib6_tables to remove expired routes. Walking a tree can be expensive if the number of routes in a table is big, even if most of them are permanent. Checking routes in a separated list of routes having expiration will avoid this potential issue. Background ========== The size of a Linux IPv6 routing table can become a big problem if not managed appropriately. Now, Linux has a garbage collector to remove expired routes periodically. However, this may lead to a situation in which the routing path is blocked for a long period due to an excessive number of routes. For example, years ago, there is a commit c7bb4b89 ("ipv6: tcp: drop silly ICMPv6 packet too big messages"). The root cause is that malicious ICMPv6 packets were sent back for every small packet sent to them. These packets add routes with an expiration time that prompts the GC to periodically check all routes in the tables, including permanent ones. Why Route Expires ================= Users can add IPv6 routes with an expiration time manually. However, the Neighbor Discovery protocol may also generate routes that can expire. For example, Router Advertisement (RA) messages may create a default route with an expiration time. [RFC 4861] For IPv4, it is not possible to set an expiration time for a route, and there is no RA, so there is no need to worry about such issues. Create Routes with Expires ========================== You can create routes with expires with the command. For example, ip -6 route add 2001:b000:591::3 via fe80::5054:ff:fe12:3457 \ dev enp0s3 expires 30 The route that has been generated will be deleted automatically in 30 seconds. GC of FIB6 ========== The function called fib6_run_gc() is responsible for performing garbage collection (GC) for the Linux IPv6 stack. It checks for the expiration of every route by traversing the trees of routing tables. The time taken to traverse a routing table increases with its size. Holding the routing table lock during traversal is particularly undesirable. Therefore, it is preferable to keep the lock for the shortest possible duration. Solution ======== The cause of the issue is keeping the routing table locked during the traversal of large trees. To solve this problem, we can create a separate list of routes that have expiration. This will prevent GC from checking permanent routes. Result ====== We conducted a test to measure the execution times of fib6_gc_timer_cb() and observed that it enhances the GC of FIB6. During the test, we added permanent routes with the following numbers: 1000, 3000, 6000, and 9000. Additionally, we added a route with an expiration time. Here are the average execution times for the kernel without the patch. - 120020 ns with 1000 permanent routes - 308920 ns with 3000 ... - 581470 ns with 6000 ... - 855310 ns with 9000 ... The kernel with the patch consistently takes around 14000 ns to execute, regardless of the number of permanent routes that are installed. Majro changes from v5: - Force syncrhonize GC before query expired routes with "sysctl -wq net.ipv6.route.flush=1". Major changes from v4: - Fix the comment of fib6_add_gc_list(). Major changes from v3: - Move the checks of f6i->fib6_node to fib6_add_gc_list(). - Make spin_lock_bh() and spin_unlock_bh() stands out. - Explain the reason of the changes in the commit message of the patch 4. Major changes from v2: - Refactory the boilerplate checks in the test case. - check_rt_num() and check_rt_num_clean() Major changes from v1: - Reduce the numbers of routes (5) in the test cases to work with slow environments. Due to the failure on patchwork. - Remove systemd related commands in the test case. Major changes from the previous patchset [2]: - Split helpers. - fib6_set_expires() -> fib6_set_expires() and fib6_add_gc_list(). - fib6_clean_expires() -> fib6_clean_expires() and fib6_remove_gc_list(). - Fix rt6_add_dflt_router() to avoid racing of setting expires. - Remove unnecessary calling to fib6_clean_expires() in ip6_route_info_create(). - Add test cases of toggling routes between permanent and temporary and handling routes from RA messages. - Clean up routes by deleting the existing device and adding a new one. - Fix a potential issue in modify_prefix_route(). ==================== Signed-off-by:

Add tests of changing permanent routes to temporary routes and the reversed case to make sure GC working correctly in these cases. Add tests for the temporary routes from RA. The existing device will be deleted between tests to remove all routes associated with it, so that the earlier tests don't mess up the later ones. Reviewed-by:

Make the decision to set or clean the expires of a route based on the RTF_EXPIRES flag, rather than the value of the "expires" argument. This patch doesn't make difference logically, but make inet6_addr_modify() and modify_prefix_route() consistent. The function inet6_addr_modify() is the only caller of modify_prefix_route(), and it passes the RTF_EXPIRES flag and an expiration value. The RTF_EXPIRES flag is turned on or off based on the value of valid_lft. The RTF_EXPIRES flag is turned on if valid_lft is a finite value (not infinite, not 0xffffffff). Even if valid_lft is 0, the RTF_EXPIRES flag remains on. The expiration value being passed is equal to the valid_lft value if the flag is on. However, if the valid_lft value is infinite, the expiration value becomes 0 and the RTF_EXPIRES flag is turned off. Despite this, modify_prefix_route() decides to set the expiration value if the received expiration value is not zero. This mixing of infinite and zero cases creates an inconsistency. Reviewed-by:

Pass the duration of a lifetime (in seconds) to the function rt6_add_dflt_router() so that it can properly set the expiration time. The function ndisc_router_discovery() is the only one that calls rt6_add_dflt_router(), and it will later set the expiration time for the route created by rt6_add_dflt_router(). However, there is a gap of time between calling rt6_add_dflt_router() and setting the expiration time in ndisc_router_discovery(). During this period, there is a possibility that a new route may be removed from the routing table. By setting the correct expiration time in rt6_add_dflt_router(), we can prevent this from happening. The reason for setting RTF_EXPIRES in rt6_add_dflt_router() is to start the Garbage Collection (GC) timer, as it only activates when a route with RTF_EXPIRES is added to a table. Suggested-by:

Christian Marangi says: ==================== net: phy: Introduce PHY Package concept Idea of this big series is to introduce the concept of PHY package in DT and give PHY drivers a way to derive the base address from DT. The concept of PHY package is nothing new and is already a thing in the kernel with the API phy_package_join/leave/read/write. What is currently lacking is describing this in DT and better reference a base address to calculate offset from. In the scenario of a PHY package where multiple address are used and there isn't a way to get the base address of the PHY package from some regs, getting the information from DT is the only way. A possible example to this problem is this: ethernet-phy-package@0 { compatible = "qcom,qca8075-package"; #address-cells = <1>; #size-cells = <0>; reg = <0>; qcom,package-mode = "qsgmii"; ethernet-phy@1 { reg = <1>; }; phy4: ethernet-phy@4 { reg = <4>; }; }; The mdio parse functions are changed to address for this additional special node, the function is changed to simply detect this node and search also in this. (we match the node name to be "ethernet-phy-package") PHY driver can then use introduced helper of_phy_package_join to join the PHY to the PHY package and derive the base address from DT. Changes v7: - Rebase on top of net-next - Add Reviewed-by tag for DT patch - Change tx-driver-strength to tx-drive-strength - Drop driver reference in DT Changes v6: - Back to absolute PHY implementation - Correctly drop refcount for node on error condition and on PHY leave - Drop DT include patch in favor for 3 boolean vendor property - Fix Documentation problem for compatible and missing type and description - Drop redundand gpio-controller dependency and description - Skip scanphy with invalid PHY Package node and make reg mandatory - Rework fiber read status to use more generic function - Split qca808x LED generalization patch to permit easier review - Correctly return -EINVAL with wrong data passed to vendor property - Drop removing LED ops for qca807x PHY driver with gpio-controller Changes v5: - Rebase on top of net-next - Change implementation to base addr + offset in subnode - Adapt to all the changes and cleanup done to at803x Changes v4: - Rework DT implementation - Drop of autojoin support and rework to simple helper - Rework PHY driver to the new implementation - Add compatible for qca807x package - Further cleanup patches Changes v3: - Add back compatible implementation - Detach patch that can be handled separately (phy_package_mmd, phy_package extended) - Rework code to new simplified implementation with base addr + offset - Improve documentation with additional info and description Changes v2: - Drop compatible "ethernet-phy-package", use node name prefix matching instead - Improve DT example - Add reg for ethernet-phy-package - Drop phy-mode for ethernet-phy-package - Drop patch for generalization of phy-mode - Drop global-phy property (handle internally to the PHY driver) - Rework OF phy package code and PHY driver to handle base address - Fix missing of_node_put - Add some missing docs for added variables in struct - Move some define from dt-bindings include to PHY driver - Handle qsgmii validation in PHY driver - Fix wrong include for gpiolib - Drop reduntant version.h include ==================== Signed-off-by: -

This adds driver for the Qualcomm QCA8072 and QCA8075 PHY-s. They are 2 or 5 port IEEE 802.3 clause 22 compliant 10BASE-Te, 100BASE-TX and 1000BASE-T PHY-s. They feature 2 SerDes, one for PSGMII or QSGMII connection with MAC, while second one is SGMII for connection to MAC or fiber. Both models have a combo port that supports 1000BASE-X and 100BASE-FX fiber. PHY package can be configured in 3 mode following this table: First Serdes mode Second Serdes mode Option 1 PSGMII for copper Disabled ports 0-4 Option 2 PSGMII for copper 1000BASE-X / 100BASE-FX ports 0-4 Option 3 QSGMII for copper SGMII for ports 0-3 copper port 4 Each PHY inside of QCA807x series has 4 digitally controlled output only pins that natively drive LED-s. But some vendors used these to driver generic LED-s controlled by userspace, so lets enable registering each PHY as GPIO controller and add driver for it.

These are variant of the manual phy_package_join with the difference that these will use DT nodes to derive the base_addr instead of manually passing an hardcoded value. An additional value is added in phy_package_shared, "np" to reference the PHY package node pointer in specific PHY driver probe_once and config_init_once functions to make use of additional specific properties defined in the PHY package node in DT. The np value is filled only with of_phy_package_join if a valid PHY package node is found. A valid PHY package node must have the node name set to "ethernet-phy-package". Signed-off-by:

Document ethernet PHY package nodes used to describe PHY shipped in bundle of 2-5 PHY. The special node describe a container of PHY that share common properties. This is a generic schema and PHY package should create specialized version with the required additional shared properties. Example are PHY packages that have some regs only in one PHY of the package and will affect every other PHY in the package, for example related to PHY interface mode calibration or global PHY mode selection. The PHY package node MUST declare the base address used by the PHY driver for global configuration by calculating the offsets of the global PHY based on the base address of the PHY package. Each reg of the PHYs defined in the PHY package node is absolute and describe the real address of the Ethernet PHY on the bus. Signed-off-by:

udpgso regression test configures routing and device MTU directly through uAPI (Netlink, ioctl) to do its job. While there is nothing wrong with it, it takes more effort than doing it from shell. Looking forward, we would like to extend the udpgso regression tests to cover the EIO corner case [1], once it gets addressed. That will require a dummy device and device feature manipulation to set it up. Which means more Netlink code. So, in preparation, pull out network configuration into the shell script part of the test, so it is easily extendable in the future. Also, because it now easy to setup routing, add a second local IPv6 address. Because the second address is not managed by the kernel, we can "replace" the corresponding local route with a reduced-MTU one. This unblocks the disabled "ipv6 connected" test case. Add a similar setup for IPv4 for symmetry. [1] https://lore.kernel.org/netdev/87jzqsld6q.fsf@cloudflare.com/Reviewed-by:
