Commit 8fce33317023 introduced the concept of NAPI per-channel and independent cleaning of TX path. This is currently breaking performance in some cases. The scenario happens when all packets are being received in Queue 0 but the TX is performed in Queue != 0. Fix this by using different NAPI instances per each TX and RX queue, as suggested by Florian.

2019-02-21bonding: fix PACKET_ORIGDEV regressionMichal Soltys
This patch fixes a subtle PACKET_ORIGDEV regression which was a side effect of fixes introduced by: 6a9e461f6fe4 bonding: pass link-local packets to bonding master also. ... to: b89f04c61efe bonding: deliver link-local packets with skb->dev set to link that packets arrived on While 6a9e461f6fe4 restored pre-b89f04c61efe presence of link-local packets on bonding masters (which is required e.g. by linux bridges participating in spanning tree or needed for lab-like setups created with group_fwd_mask) it also caused the originating device information to be lost due to cloning. Maciej Żenczykowski proposed another solution that doesn't require packet cloning and retains original device information - instead of returning RX_HANDLER_PASS for all link-local packets it's now limited only to packets from inactive slaves. At the same time, packets passed to bonding masters retain correct information about the originating device and PACKET_ORIGDEV can be used to determine it. This elegantly solves all issues so far: - link-local packets that were removed from bonding masters - LLDP daemons being forced to explicitly bind to slave interfaces - PACKET_ORIGDEV having no effect on bond interfaces Fixes: 6a9e461f6fe4 (bonding: pass link-local packets to bonding master also.)

2019-02-21i40e: fix XDP_REDIRECT/XDP xmit ring cleanup raceBjörn Töpel
When the driver clears the XDP xmit ring due to re-configuration or teardown, in-progress ndo_xdp_xmit must be taken into consideration. The ndo_xdp_xmit function is typically called from a NAPI context that the driver does not control. Therefore, we must be careful not to clear the XDP ring, while the call is on-going. This patch adds a synchronize_rcu() to wait for napi(s) (preempt-disable regions and softirqs), prior clearing the queue. Further, the __I40E_CONFIG_BUSY flag is checked in the ndo_xdp_xmit implementation to avoid touching the XDP xmit queue during re-configuration.

2019-02-21ixgbe: fix potential RX buffer starvation for AF_XDPMagnus Karlsson
When the RX rings are created they are also populated with buffers so that packets can be received. Usually these are kernel buffers, but for AF_XDP in zero-copy mode, these are user-space buffers and in this case the application might not have sent down any buffers to the driver at this point. And if no buffers are allocated at ring creation time, no packets can be received and no interrupts will be generated so the NAPI poll function that allocates buffers to the rings will never get executed. To rectify this, we kick the NAPI context of any queue with an attached AF_XDP zero-copy socket in two places in the code. Once after an XDP program has loaded and once after the umem is registered. This take care of both cases: XDP program gets loaded first then AF_XDP socket is created, and the reverse, AF_XDP socket is created first, then XDP program is loaded.
