Here's an untested patch that you could try:
diff -r 62ccc35abd89 sys/dev/cxgbe/t4_main.c

{
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.
