Subject: [55/55] atm: [br2684] allow routed mode operation again

2.6.32-longterm review patch.  If anyone has any objections, please let us know.

------------------

From: chas williams - CONTRACTOR <chas@....nrl.navy.mil>

commit 2e302ebfeac04beb5a5d6af1ac583c6a1fb76d1a upstream.

in routed mode, we don't have a hardware address so netdev_ops doesnt
need to validate our hardware address via .ndo_validate_addr
