The user's coal configuration will be lost after reset, so the tx_coal and rx_coal fields are added to the struct hns_nic_priv to save the coal configuration and used to restore the user's configuration after the reset is complete.

The current hns3_get_max_available_channels returns the total number of queues for the device, which makes ethtool -L set the number of queues per channel queues incorrectly, so hns3_get_max_available_channels should return the maximum available number of queues per channel, depending on the total number of queues allocated and the hardware configurations.

Currently hns3_nic_change_mtu will try to down the netdev before setting mtu, and it does not up the netdev when the setting fails, which causes netdev not up problem. This patch fixes it by not returning when the setting fails. Fixes: a8e8b7ff ("net: hns3: Add support to change MTU in HNS3 hardware") Signed-off-by:

The hardware expects a unit of 128 bytes when setting packet buffer. When calculating the packet buffer size, hclge_rx_buffer_calc does not round up the size as a unit of 128 byte, which may casue packet lost problem when stress testing. This patch fixes it by rounding up packet size when calculating. Fixes: 46a3df9f ("net: hns3: Add HNS3 Acceleration Engine & Compatibility Layer Support") Signed-off-by:

When B53_SERDES is a loadable module, a built-in srab driver still cannot reach it, so the previous fix is incomplete: b53_srab.c:(.text+0x3f4): undefined reference to `b53_serdes_init' drivers/net/dsa/b53/b53_srab.o:(.rodata+0xe64): undefined reference to `b53_serdes_link_state' drivers/net/dsa/b53/b53_srab.o:(.rodata+0xe74): undefined reference to `b53_serdes_link_set' drivers/net/dsa/b53/b53_srab.o:(.rodata+0xe88): undefined reference to `b53_serdes_an_restart' drivers/net/dsa/b53/b53_srab.o:(.rodata+0xea0): undefined reference to `b53_serdes_phylink_validate' drivers/net/dsa/b53/b53_srab.o:(.rodata+0xea4): undefined reference to `b53_serdes_config' Add a Kconfig dependency that forces srab to also be a module in this case, but allow it to be built-in when serdes is disabled or built-in.

Johannes Berg says: ==================== netlink: nested policy validation This adds nested policy validation, which lets you specify the nested attribute type, e.g. NLA_NESTED with sub-policy, or the new NLA_NESTED_ARRAY with sub-sub-policy. Changes in v2: * move setting the bad attr pointer/message into validate_nla() * remove the recursion patch since that's no longer needed * simply skip the generic bad attr pointer/message setting in case of nested nla_validate() failing since that could fail only due to validate_nla() failing inside, which already sets the extack information Changes in v3: * fix NLA_REJECT to have an error message if none is in policy ==================== Signed-off-by: -

Sometimes nested netlink attributes are just used as arrays, with the nla_type() of each not being used; we have this in nl80211 and e.g. NFTA_SET_ELEM_LIST_ELEMENTS. Add the ability to validate this type of message directly in the policy, by adding the type NLA_NESTED_ARRAY which does exactly this: require a first level of nesting but ignore the attribute type, and then inside each require a second level of nested and validate those attributes against a given policy (if present). Note that some nested array types actually require that all of the entries have the same index, this is possible to express in a nested policy already, apart from the validation that only the one allowed type is used.

Now that we have a validation_data pointer, and the len field in the policy is unused for NLA_NESTED, we can allow using them both to have nested validation. This can be nice in code, although we still have to use nla_parse_nested() or similar which would also take a policy; however, it also serves as documentation in the policy without requiring a look at the code. Signed-off-by:

Johannes Berg authored
This unifies the code between nla_parse() which sets the bad attribute pointer and an error message, and nla_validate() which only sets the bad attribute pointer. It also cleans up the code for NLA_REJECT and paves the way for nested policy validation, as it will allow us to easily skip setting the "generic" message without any extra args like the **error_msg now, just passing the extack through is now enough. While at it, remove the unnecessary label in nla_parse(). Suggested-by:

The validation data is only used within the policy that should usually already be const, and isn't changed in any code that uses it. Therefore, make the validation_data pointer const. While at it, remove the duplicate variable in the bitfield validation that I'd otherwise have to change to const. Reviewed-by:

The mvneta controller can handle speeds up to 2500Mbps on the SGMII interface. This relies on serdes configuration, the lane must be configured at 3.125Gbps and we can't use in-band autoneg at that speed. The main issue when supporting that speed on this particular controller is that the link partner can send ethernet frames with a shortened preamble, which if not explicitly enabled in the controller will cause unexpected behaviours. This was tested on Armada 385, with the comphy configuration done in bootloader. Signed-off-by:

This patch improves the guest receive performance. On the handle_tx side, we poll the sock receive queue at the same time. handle_rx do that in the same way. We set the poll-us=100us and use the netperf to test throughput and mean latency. When running the tests, the vhost-net kthread of that VM, is alway 100% CPU. The commands are shown as below. Rx performance is greatly improved by this patch. There is not notable performance change on tx with this series though. This patch is useful for bi-directional traffic. netperf -H IP -t TCP_STREAM -l 20 -- -O "THROUGHPUT, THROUGHPUT_UNITS, MEAN_LATENCY" Topology: [Host] ->linux bridge -> tap vhost-net ->[Guest] TCP_STREAM: * Without the patch: 19842.95 Mbps, 6.50 us mean latency * With the patch: 37598.20 Mbps, 3.43 us mean latency Signed-off-by:

After sk_state exposed, we can get in which state this retransmission occurs. That could give us more detail for dignostic. For example, if this retransmission occurs in SYN_SENT state, it may also indicates that the syn packet may be dropped on the remote peer due to syn backlog queue full and then we could check the remote peer. BTW,SYNACK retransmission is traced in tcp_retransmit_synack tracepoint. Signed-off-by:

Nikolay Aleksandrov says: ==================== net: bridge: convert bool options to bits A lot of boolean bridge options have been added around the net_bridge structure resulting in holes and more importantly different cache lines that need to be fetched in the fast path. This set moves all of those to bits in a bitfield which resides in a hot cache line thus reducing the size of net_bridge, the number of holes and the number of cache lines needed for the fast path. The set is also sent in preparation for new boolean options to avoid spreading them in the structure and making new holes. One nice side-effect is that we avoid potential race conditions by using the bitops since some of the options were bits being directly set in parallel risking hard to debug issues (has_ipv6_addr). Before: size: 1184, holes: 8, sum holes: 30 After: size: 1160, holes: 3, sum holes: 7 Patch 01 is a trivial style fix Patch 02 adds the new options bitfield and converts the vlan boolean options to bits Patches 03-08 convert the rest of the boolean options to bits Patch 09 re-arranges a few fields in net_bridge to further reduce size v2: patch 09: remove the comment about offload_fwd_mark in net_bridge and leave it where it is now, thanks to Ido for spotting it ==================== Signed-off-by:
