A quick grep shows just below 100 occurances of mac.raw under
drivers/net.  I'll have a go at it unless someone else does
it first.

On the other hand, I've found a way to avoid the move without
requiring mac_len to be set at all.  We can do this in netif_rx:

if (mac_len == 0)
	mac_len = nh - raw

And in xfrm_rcv we can do

if (mac_len == 0)
	raw = data

Cheers,
