This delta adds two bug fixes: one that makes HW Offload logic in

Browse Source 
legacy codepath match the 82575, without this we were seeing bridging
fail on 82546 adapters. Secondly, I have limited TSO to PCI Express
adapters, I meant to do this and it got dropped in the earlier delta.
Next, I am dropping in the latest shared code from our development
team, consensus was that this should be done frequently, so I am :)
