vlan(4) broken.

[Gary Allan <dragonfly@xxxxxxxxxxxxxxx>]

Hello,

I have been experiencing problems with vlan(4) on DragonFlyBSD HEAD.
Received tagged packets are not being passed down to ether_input()
correctly and transmitted packets are not being tagged. [Packet capture
shows no 802.1Q header on transmitted packets from DragonFlyBSD PC.]

The error message "ether_input got mbuf without embedded
ethernet header" was added to if_ethersubr.c during the recent if_bridge 
import.

I have included details below.

Regards

G.Allan
