Subject: [net-2.6 PATCH 2/7] qlge: Fix frame routing issue related to bonding.

Currently frames are routed based on their type and MAC address. This
patch adds the port number on which the frame arrived to the routing.
This prevents problems in the case where both interfaces have the same MAC address in
a routing configuration.
