Bonding ALB sends bogus packets

The bonding ALB mode builds packets with type, ETH_P_LOOP.

Well ETH_P_LOOP is defined as 0x0060 which looks completely bogus.
All Ethernet types less than 1536 are interpreted as 802.2 frames.
The result is that the resulting packet looks like a bogus 802.2
frame to the other host (or switch).  I have no idea what the 
initial design was or what the purpose of this code is, but it
should either send a real packet or nothing at all.
