In IEEE Std 1588™-2019, 01-80-C2-00-00-0E multicast address is defined for multicast (ITU-T G.8275.1 profile) scenario.
In CNI plugin bridge, packet with 01-80-C2-00-00-0E is silently dropped since it locates in MAC address range for LLDP.
In kernel bridge implementation, echo 16384 > /sys/class/net//bridge/group_fwd_mask is provided to change the default (silent drop) behavior to normally (MAC based) forward.
But this option provided by kernel can't be set into CNI, due to NO configuration parameter for it.
Can CNI plugin - bridge, add one additional parameter group_fwd_mask, to activate the bridge function which is already provided in kernel ?
