Hi Herbert,

I'll give these patches a try within a day or two.
Please note that the 6Gb/s rate is achieved on a low perf server.
Using this server makes it easy to witness the impact of optimizations.
Faster boxes reach line rate.
Just want to make clear that cxgb3 HW is not limited to 6Gb/s ;)

Cheers,
Divy
