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 :) Approved by: pdeuskar
