Are the VLAN interfaces trunked on the FreeBSD side (i.e. vlanN)?

Are you getting bitten by the device driver dropping large frames
(VLAN trunks need a higher MRU/MTU, which no drivers seem to support;
see http://www.euitt.upm.es/~pjlobo/fbsdvlan.html for if_fxp patches)
If you set the MTU to 1496 do things get better?
