I like piggybacking as much as the next guy, and pushed for a bunch of
it in the past, but are the files being transferred really that small
relative to the RTT that the savings of the standalone ACK of the
SYN|ACK really buys that much?
I'm sure it does nice things for a default netperf TCP_CRR test, shaving
one segment out of 8 or so, and maybe even more on a TCP_CC test, but
how many sub-MSS files are transferred these days?
