According to POSIX, that supplies TCP_NODELAY, and a look into the
file here finds these other symbols we care about:
#define TCP_KEEPIDLE 4 /* Start keeplives after this period */
#define TCP_KEEPINTVL 5 /* Interval between keepalives */
#define TCP_KEEPCNT 6 /* Number of keepalives before death */
Probably you could drop it from any file not using any TCP_xxx
symbols. I'd be a little wary of #ifdef checks in any file you're
about to remove it from, though, as those could mask any obvious
breakage.
