Summary0015758: macvlan driver drops multicast udp packets under relatively moderate load
DescriptionIn using the macvlan kernel driver in bridge mode (via kubernetes cni), with macvlan tied to bond0.2 bound to eth1 within a docker container under moderate load. We can pass twice the traffic running without the vlan (we expected some drop off but not cut in half). dropwatch shows ip_rcv_finish dropping packets. We see the rx_dropped counter increase on the bond0.2 interface. We don't see any drops within the container namespaced interface (eth1). We also see no application-level drops (as would show up in netstat -s --udp). With tcpdump, we don't see any vlan tagging issues from the switch. iftop (and the application in question) shows significant packet loss; however. No drops from the NIC/ethtool perspective (and the packets make it through the physical interfaces (eno1 and eno2). Hardware configuration is attached. macvlan kernels threads show significant CPU utilization.
