[PATCH] Ethernet cleanup; 802.1p input and M_PROMISC

[Bruce M Simpson]

Hello all,

I would like to announce an updated version of the 802.1p input patch, 
available at:
    http://people.freebsd.org/~bms/dump/latest-8021p.diff

I have cut down the original scope of the patch. I previously ran into 
problems when I tried to move VLAN tag input and output processing into 
if_ethersubr.c.

FreeBSD should now accept VLAN 0 traffic on input with this patch. In 
addition to this, the M_PROMISC flag is now used, which considerably 
simplifies the Ethernet input path in general.

I have performed some light testing on a 1Gbps COTS switch with 802.1q 
encapsulation and without, with carp and vlan, with and without hardware 
VLAN tagging, and all looks OK. I would greatly appreciate further 
testing, particularly with if_bridge and ng_ether which I have not tried.

If all goes to plan, I would hope to commit this code to -CURRENT within 
the next 10 days.

Regards,
BMS
