 Here's an untested patch that you could try:
 
 diff -r 62ccc35abd89 sys/dev/cxgbe/t4_main.c
 --- a/sys/dev/cxgbe/t4_main.c	Wed Oct 03 15:57:10 2012 -0700

   {
   	struct ifnet *vlan;
 
 -	if (arg != ifp)
 +	if (arg != ifp || ifp->if_type != IFT_ETHER)
   		return;
 
   	vlan = VLAN_DEVAT(ifp, vid);
 
 
 By the way, I noticed your kernel name is CXGBETOE.  Keep in mind that 
 hw TCP offload over an if_lagg is unimplemented as of now.  TCP offload 
 over an if_vlan directly over cxgbe will work just fine.
