In -CURRENT my changes to the ethernet input path maintain the use of 
ETHER_MAX_FRAME() however the check is folded under #ifdef DIAGNOSTIC. I 
don't recall adding this conditional or touching it so it seems to be 
something which was already thereo radded by someone else.

Could be pilot error; its use in -CURRENT seems to apply strictly to the 
use of large-receive offload (LRO).
