Enable the following TCP options by default to give it more exposure:
rfc3042 Limited retransmit rfc3390 Increasing TCP's initial congestion Window inflight TCP inflight bandwidth limiting All my production server have it enabled and there have been no issues. I am confident about having them on by default and it gives us better overall TCP performance. Reviewed by: sam (mentor)
