Horrendous upload network performance with VLAN (download seems OK)

[Patrick Proniewski]

I did and it failed, but maybe I've not used the right syntax:

	# ifconfig bxe0 -vlanmtu
	ifconfig: -vlanmtu: Invalid argument

man bxe makes me think that this driver won't allow this kind of changes.

Ping is OK, I can ssh to this server, transfer rate to the server (down) is not fantastic but OK, enough to perform pkg installation or FreeBSD update. Transfer rate from the server to the rest of the world is abysmal, often stalling after few 100's KB.
