when the frame is VJ compressed we need to reserve space for the    ethernet
header if forwarding is enabled. The symptom this fixes is that the first data
frame after a TCP connection is established can be lost as there is no room to
add in the ethernet header in the pbuf, and re-sends hit the same issue,
resulting in the TCP connection never sending the first block of data and thus
stalling.
