The Microsemi Ocelot can mux SerDes lanes (aka macros) to different switch ports or even make it act as a PCIe interface. This adds support for the muxing of the SerDes. Signed-off-by:

The Microsemi Ocelot has multiple SerDes and requires that the SerDes be muxed accordingly to the hardware representation. Let's add a constant for each SerDes available in the Microsemi Ocelot. Reviewed-by:

Since HSIO address space can be accessed by different drivers, let's simplify the register address definitions so that it can be easily used by all drivers and put the register address definition in the include/soc/mscc/ocelot_hsio.h header file. Reviewed-by:

HSIO address space was moved to a syscon, hence we need to get the regmap of this address space from there and no more from the device node. Reviewed-by:

HSIO register address space should be handled outside of the MAC controller as there are some registers for PLL5 configuring, SerDes/switch port muxing and a thermal sensor IP, so let's remove it. Acked-by:

Salil Mehta says: ==================== Fixes, minor changes & cleanups for the Unicast MAC VLAN table This patch-set presents necessary modifications, fixes & cleanups related to Unicast MAC Vlan Table to support revision 0x21 hardware. ==================== Signed-off-by: -
Jian Shen authored
In revision 0x20, we use vlan id != 0 to check whether a vlan tag has been offloaded, so vlan id 0 is not supported. In revision 0x21, rx buffer descriptor adds two bits to indicate whether one or more vlan tags have been offloaded, so vlan id 0 is valid now. This patch seperates the handle for vlan id 0, add vlan id 0 support for revision 0x21. Fixes: 5b5455a9 ("net: hns3: Add STRP_TAGP field support for hardware revision 0x21") Signed-off-by:

In previously implement for unicast mac vlan table, the space is shared by all the functions, driver does nothing when the space is exhausted. This patch preallocates the space of unicast mac vlan table for each function by software. Each function can only use its private space and available shared space, avoiding single function exhausts too much space, and other functions are unable to add unicast mac address. Signed-off-by:

In original codes, the mac vlan table entries are not cleared when unload hns3 driver. The dirty mac vlan table entries will make the result of looking up mac vlan table being unexpected. When doing core reset or global reset, the firmware will clear all the tables for driver, and driver shouldn't send any commands to firmware during reset. But when doing function reset, the driver needs to clear the tables itself. This patch clears the mac vlan table entries for each client when unload driver or reset. Signed-off-by:

In commit ec3ed293 ("net_sched: change tcf_del_walker() to take idrinfo->lock") we move fl_hw_destroy_tmplt() to a workqueue to avoid blocking with the spinlock held. Unfortunately, this causes a lot of troubles here: 1. tcf_chain_destroy() could be called right after we queue the work but before the work runs. This is a use-after-free. 2. The chain refcnt is already 0, we can't even just hold it again. We can check refcnt==1 but it is ugly. 3. The chain with refcnt 0 is still visible in its block, which means it could be still found and used! 4. The block has a refcnt too, we can't hold it without introducing a proper API either. We can make it working but the end result is ugly. Instead of wasting time on reviewing it, let's just convert the troubling spinlock to a mutex, which allows us to use non-atomic allocations too.

David Ahern says: ==================== net: Consolidate metrics handling for ipv4 and ipv6 As part of the IPv6 fib info refactoring, the intent was to make metrics handling for ipv6 identical to ipv4. One oversight in ip6_dst_destroy led to confusion and a couple of incomplete attempts at finding and fixing the resulting memory leak which was ultimately resolved by ce7ea4af ("ipv6: fix memory leak on dst->_metrics"). Refactor metrics hanlding make the code really identical for v4 and v6, and add a few test cases. ==================== Signed-off-by:

As Michal remaind, we should allow to clear ttl inherit. Then we will have three states: 1. set the flag, and do ttl inherit. 2. do not set the flag, use configured ttl value, or default ttl (0) if not set. 3. disable ttl inherit, use previous configured ttl value, or default ttl (0).

This traffic scheduler allows traffic classes states (transmission allowed/not allowed, in the simplest case) to be scheduled, according to a pre-generated time sequence. This is the basis of the IEEE 802.1Qbv specification. Example configuration: tc qdisc replace dev enp3s0 parent root handle 100 taprio \ num_tc 3 \ map 2 2 1 0 2 2 2 2 2 2 2 2 2 2 2 2 \ queues 1@0 1@1 2@2 \ base-time 1528743495910289987 \ sched-entry S 01 300000 \ sched-entry S 02 300000 \ sched-entry S 04 300000 \ clockid CLOCK_TAI The configuration format is similar to mqprio. The main difference is the presence of a schedule, built by multiple "sched-entry" definitions, each entry has the following format: sched-entry <CMD> <GATE MASK> <INTERVAL> The only supported <CMD> is "S", which means "SetGateStates", following the IEEE 802.1Qbv-2015 definition (Table 8-6). <GATE MASK> is a bitmask where each bit is a associated with a traffic class, so bit 0 (the least significant bit) being "on" means that traffic class 0 is "active" for that schedule entry. <INTERVAL> is a time duration in nanoseconds that specifies for how long that state defined by <CMD> and <GATE MASK> should be held before moving to the next entry. This schedule is circular, that is, after the last entry is executed it starts from the first one, indefinitely. The other parameters can be defined as follows: - base-time: specifies the instant when the schedule starts, if 'base-time' is a time in the past, the schedule will start at base-time + (N * cycle-time) where N is the smallest integer so the resulting time is greater than "now", and "cycle-time" is the sum of all the intervals of the entries in the schedule; - clockid: specifies the reference clock to be used; The parameters should be similar to what the IEEE 802.1Q family of specification defines.

This patch adds support for following generic permanent mode devlink parameters. They can be modified using devlink param commands. msix_vec_per_pf_max - This param sets the number of MSIX vectors that the device requests from the host on driver initialization. This value is set in the device which limits MSIX vectors per PF. msix_vec_per_pf_min - This param sets the number of minimal MSIX vectors required for the device initialization. Value 0 indicates a default value is selected. This value is set in the device which limits MSIX vectors per PF. Cc: Michael Chan <michael.chan@broadcom.com> Signed-off-by:
