Rather than special casing this around vlan filtering, I would prefer
the code always forward these packets, or manipulate group_fwd_mask
to allow it that way.

These addresses must be forwarded only if the bridge is an S-VLAN
bridge. When it is a C-VLAN bridge or a .1D bridge, they may not be
forwarded. So, I don't think we can forward them always.

Using group_fwd_mask is a bit complicated. If we use it to forward them,
user can optionally turn off forwarding ability of those addresses...
but we maybe need another information (named like group_fwd_mask_set)
that indicates which bit is set by user. (We have to set group_fwd_mask
automatically when we set vlan_proto to 88a8.)
Is this way acceptable?

May be separate it into required mask and user mask.  Set required
mask when this is an S-VLAN bridge.

Sounds like a good idea.
I'll give it a try, thank you for your suggestion.

Thanks,
