	There really isn't a high level design document.

	The input path goes from the driver, which (probably) calls
netif_receive_skb.  That function does its processing whatnot, the only
special step for bonding is the processing done by skb_bond() which
assigns the packet to the bonding device.  In the current mainline,
skb_bond() also does some stuff to drop traffic on inactive slaves as
the like.

	After that, the packet follows the regular input path in
netif_skb_receive.
