Nice, looks good. I have a similar patch as well and was going to ask wouldn’t
it be
better to make empty stubs which return an error when vlan filtering isn’t
configured
and drop the ifdefs in the netlink handling code ?
Similar to how vlan_filtering netlink attribute is handled in commit:
a7854037da00 ("bridge: netlink: add support for vlan_filtering attribute”)
Potential problem would be the return of the protocol, but I think if 0 is
returned that
can be handled.
Cheers,
Nik
