>Description:
vxget() in if_vx.c almost always store packet into multiple mbufs.
It makes upper-layer protocol processing slightly slower.
The code looks awful (I'm not attacking the author, sorry) and
can be simplified/can be made more readable.

it would be better if:
	packet > MHLEN to be put into single external mbuf
	otherwise store into single internal mbuf


The problem still remains in the latest source in CVS branch.

>How-To-Repeat:
none
>Fix:
I'll try it later if nobody does it.
