Shirish,
If we can verify that performance does not appear to be impacted (e.g. some
dbench runs against remote server and also against localhost/samba)  when
removing the few lines of code in (cifs's) ipv4_connect in which cifs sets
sndbuf/rcvbuf (we never set them in the case fortunately) - then I will
remove those lines immediately (and I am ok with not having a mount option
to turn off the autotuning ie revert to old behavior)
