vlan/bridging broken in 4.8-release?

[Marco Wertejuk]

Hello Maxim,

today I've tried your hack and it works, at least it seems so.

It was not exactly the same setup but nearly the same.
The bridge has two interfaces (fxp0, fxp1) and
one host is connected to each interface (using crosslink
cables, no other networking devices such as broken HP
ProCurve switches).
The host on fxp1 (10.10.10.16) does not use vlans,
the host on fxp0 (10.10.10.18) is in vlan id 1.

tcpdump -tni fxp0, fxp1, vlan0:
(yes 10.10.10.18 has a strange mac address, because
of a broken fxp0 card I guess ;)

Two pings were send successfully with your hack and I
guess everything else would work too, but I have no
time for further testing, maybe the people who wrote
the PR have more time ...

Please make a real patch out of your hack and get it
commited into -stable because I still want to use it
for one of my customers :)

Hopefully I did not forget anything in this email :)
