The VF reps are effectively related to the same mlx5 PCI device as the PF. Since the kernel invokes the (say) delete ndo for each netdev, the FW erred on multiple vxlan dst port deletes when the port was deleted from the system. We fix that by keeping the registration to be carried out only by the PF. Since the PF serves as the uplink device, the VF reps will look up a port there and realize if they are ok to offload that.

This patch will increment the counter by the number of segments, and align the driver with the behavior of other drivers in the stack. Note that no information is lost in this patch due to 'rx_lro_packets' counter existence. Before, ethtool showed: $ ethtool -S ens6 | egrep "rx_packets|rx_lro_packets" rx_packets: 435277 rx_lro_packets: 35847 rx_packets_phy: 1935066 Now, we will see the more logical statistics: $ ethtool -S ens6 | egrep "rx_packets|rx_lro_packets" rx_packets: 1935066 rx_lro_packets: 35847 rx_packets_phy: 1935066 Fixes: e586b3b0baee ("net/mlx5: Ethernet Datapath files") Signed-off-by: Gal Pressman Cc: kernel-team@fb.com Signed-off-by: Saeed Mahameed Acked-by: Alexei Starovoitov Signed-off-by: David S.
