What I think is the least intrusive and allows for maximum flexibility
is having the VLAN bridge filtering depend on VLAN support (CONFIG_VLAN_8021Q).
There already is drivers that depend on that value to enable filtering.

And make the support of VLAN filtering in the bridge conditional like
IGMP snooping is optional
