Not quite all.  The variables tcp_keepcnt and tcp_maxpersistidle are
not accessible via sysctl (the latter is not directly related to the
current keepalives issue, but it shares the same default value -
TCPTV_KEEP_IDLE - as tcp_keepidle).

There's also the the minor nit that there's no documentation.  RTSL
may be OK for developers, but it's not really appropriate for end
users.  This is aggravated by the timers being in 500ms units - phk
tripped over this recently.
