Log Message:
net: Store a pointer to the Layer 2 Sender Hardware address in mbuf

The BSD networking stack is designed around passing a mbuf down the chain
and each layer removes the part it's interested in before passing it to
the next. This makes it easy for each layer to do it's work,
but non trivial to work backwards.

As such we now store a pointer to the Senders Hardware address in the
mbuf packet header so that protocols can perform any required validation.
