Kurt Kanzenbach says: ==================== ptp: Add generic is_sync() function as multiple PHY drivers such as micrel or TI dp83640 need to inspect whether a given skb represents a PTP Sync message, provide a generic function for it. This avoids code duplication and can be reused by future PHY IEEE 1588 implementations. ==================== Signed-off-by: -

Sebastian Andrzej Siewior says: ==================== net: Convert user to netif_rx(), part 2. This is the second batch of converting netif_rx_ni() caller to netif_rx(). The change making this possible is net-next and netif_rx_ni() is a wrapper around netif_rx(). This is a clean up in order to remove netif_rx_ni(). The brcmfmac changes are slilghtly larger because the inirq parameter can be removed. ==================== Signed-off-by: -

Dongli Zhang says: ==================== tun/tap: use kfree_skb_reason() to trace dropped skb The commit c504e5c2 ("net: skb: introduce kfree_skb_reason()") has introduced the kfree_skb_reason() to help track the reason. The tun and tap are commonly used as virtio-net/vhost-net backend. This is to use kfree_skb_reason() to trace the dropped skb for those two drivers. Changed since v1: - I have renamed many of the reasons since v1. I make them as generic as possible so that they can be re-used by core networking and drivers. Changed since v2: - declare drop_reason as type "enum skb_drop_reason" - handle the drop in skb_list_walk_safe() case for tap driver, and kfree_skb_list_reason() is introduced Changed since v3 (only for PATCH 4/4): - rename to TAP_FILTER and TAP_TXFILTER - honor reverse xmas tree style declaration for 'drop_reason' in tun_net_xmit() Changed since v4: - make kfree_skb_list() static inline - add 'computation' to SKB_CSUM comment - change COPY_DATA to UCOPY_FAULT - add 'metadata' to DEV_HDR comment - expand comment on DEV_READY - change SKB_TRIM to NOMEM - chnage SKB_PULL to HDR_TRUNC Changed since v5: - rebase to net-next The following reasons are introduced. - SKB_DROP_REASON_SKB_CSUM - SKB_DROP_REASON_SKB_GSO_SEG - SKB_DROP_REASON_SKB_UCOPY_FAULT - SKB_DROP_REASON_DEV_HDR - SKB_DROP_REASON_FULL_RING - SKB_DROP_REASON_DEV_READY - SKB_DROP_REASON_NOMEM - SKB_DROP_REASON_HDR_TRUNC - SKB_DROP_REASON_TAP_FILTER - SKB_DROP_REASON_TAP_TXFILTER This is the output for TUN device. <idle>-0 [029] ..s1. 450.727651: kfree_skb: skbaddr=0000000023d235cc protocol=0 location=00000000a6748854 reason: NOT_SPECIFIED <idle>-0 [000] b.s3. 451.165671: kfree_skb: skbaddr=000000006b5de7cc protocol=4 location=000000007c2b9eae reason: FULL_RING <idle>-0 [000] b.s3. 453.149650: kfree_skb: skbaddr=000000006b5de7cc protocol=4 location=000000007c2b9eae reason: FULL_RING <idle>-0 [000] b.s3. 455.133576: kfree_skb: skbaddr=000000006b5de7cc protocol=4 location=000000007c2b9eae reason: FULL_RING <idle>-0 [000] b.s3. 457.117566: kfree_skb: skbaddr=000000006b5de7cc protocol=4 location=000000007c2b9eae reason: FULL_RING This is the output for TAP device. arping-7053 [006] ..s1. 1000.047753: kfree_skb: skbaddr=000000008618a587 protocol=2054 location=00000000743ad4a7 reason: FULL_RING <idle>-0 [022] ..s1. 1000.778514: kfree_skb: skbaddr=000000002c1e706c protocol=0 location=00000000a6748854 reason: NOT_SPECIFIED arping-7053 [006] ..s1. 1001.047830: kfree_skb: skbaddr=000000008618a587 protocol=2054 location=00000000743ad4a7 reason: FULL_RING arping-7053 [006] ..s1. 1002.047918: kfree_skb: skbaddr=000000008618a587 protocol=2054 location=00000000743ad4a7 reason: FULL_RING arping-7053 [006] ..s1. 1003.048017: kfree_skb: skbaddr=000000008618a587 protocol=2054 location=00000000743ad4a7 reason: FULL_RING ==================== Signed-off-by:

The TUN can be used as vhost-net backend. E.g, the tun_net_xmit() is the interface to forward the skb from TUN to vhost-net/virtio-net. However, there are many "goto drop" in the TUN driver. Therefore, the kfree_skb_reason() is involved at each "goto drop" to help userspace ftrace/ebpf to track the reason for the loss of packets. The below reasons are introduced: - SKB_DROP_REASON_DEV_READY - SKB_DROP_REASON_NOMEM - SKB_DROP_REASON_HDR_TRUNC - SKB_DROP_REASON_TAP_FILTER - SKB_DROP_REASON_TAP_TXFILTER Cc: Joao Martins <joao.m.martins@oracle.com> Cc: Joe Jin <joe.jin@oracle.com> Signed-off-by:

This reverts commit a505cce6. Leon says: We already discussed that. SMC should be changed to use RDMA CQ pool API drivers/infiniband/core/cq.c. ib_poll_handler() has much better implementation (tracing, IRQ rescheduling, proper error handling) than this SMC variant. Since we will switch to ib_poll_handler() in the future, revert this patch. Link: https://lore.kernel.org/netdev/20220301105332.GA9417@linux.alibaba.com/Suggested-by:

A new devlink hw health report is now added to report and diagnose NVRAM issues.

Add an NVM test function for devlink hw reporter. In this function an NVM VPD area is read followed by a write. Test result is cached and if it is successful then the next test can be conducted only after HW_RETEST_MIN_TIME to avoid frequent writes to the NVM. Reviewed-by:

Health reporter state should be maintained over resets. Previously reporters were destroyed if the device capabilities changed, but since none of the reporters depend on capabilities anymore, this logic should be removed. Signed-off-by:

If the flow control settings have been changed, a subsequent FW reset may cause the ethernet link to toggle unnecessarily. This link toggle will increase the down time by a few seconds. The problem is caused by bnxt_update_phy_setting() detecting a false mismatch in the flow control settings between the stored software settings and the current FW settings after the FW reset. This mismatch is caused by the AUTONEG bit added to link_info->req_flow_ctrl in an inconsistent way in bnxt_set_pauseparam() in autoneg mode. The AUTONEG bit should not be added to link_info->req_flow_ctrl. Reviewed-by:

Now that NAPI has been implemented, the hardware interrupt mitigation mechanism is not needed to avoid excessive interrupt load in most cases. Reduce the default RX interrupt threshold to 1 to reduce introduced latency. This can be increased with ethtool if desired if some applications still want to reduce interrupts. Signed-off-by:

Implement NAPI and GRO receive. In addition to better performance, this also avoids handling RX packets in hard IRQ context, which reduces the IRQ latency impact to other devices. Signed-off-by:

When the RX or TX coalesce count is set to 1, there's no point in setting the delay timer value since an interrupt will already be raised on every packet, and the delay interrupt just causes extra pointless interrupts. Signed-off-by:
