Sorry, I made an error and posted my patches from an earlier
revision so a follow-up fix was missing:
---8<---
The bc_cutoff patch broke the calculation of mc_filter causing
some multicast packets to not make it through to the targeted
device.
Fix this by checking whether vlan is set instead of cutoff >= 0.
Also move the cutoff < 0 logic into macvlan_recompute_bc_filter
so that it doesn't change the mc_filter at all.
Fixes: d45276e75e90 ("macvlan: Skip broadcast queue if multicast with single receiver")
