>Organization:
Lviv Polytechnic National University
>Environment:
FreeBSD guard.polynet.lviv.ua 4.3-STABLE FreeBSD 4.3-STABLE #1: Thu Jul  5 16:19:06 EEST 2001     root@betelgeuse.polynet.lviv.ua:/stalker/obj/usr/src/sys/FIREWALL  i386
>Description:
fxp driver does not support 1500 MTU on its child VLAN interfaces
>How-To-Repeat:
ifconfig fxp0 up
ifconfig vlan0 inet 192.168.0.1 netmask 0xffffff00 vlan 1 vlandev fxp0

MTU in interface will be 1496, attempts to force 1500 MTU will result in network problems.

>Fix:
current fxp codebase claims to integrate Peter Lobo patch for VLAn support. Original code + patch worked properly handling longer Ethernet frames and MTU 1500 on vlan interfaces.
