History
Matthew N. Dodd 4af90a4da4 Make sure that the entire header is in the first mbuf before we 
attempt to copy the ethernet header forward and otherwise encapsulate
a packet for output.

This fixes the panic when using VLAN devices on hardware that doesn't
do 802.1Q tagging onboard.  (That is to say, all drivers except the Tigon.)

My tests consisted of telnet, ttcp, and a pingflood of packets
between 1 and 1600 (plus headers) bytes.

MFC to follow in 1 week.
