tcp_subr.c tcp_syncache.c tcp_timer.c
tcp_timer.h tcp_usrreq.c tcp_var.h
Log:
Change the TCP timer system from using the callout system five times
directly to a merged model where only one callout, the next to fire,
is registered.
Instead of callout_reset(9) and callout_stop(9) the new function
tcp_timer_activate() is used which then internally manages the callout.
The single new callout is a mutex callout on inpcb simplifying the
locking a bit.
tcp_timer() is the called function which handles all race conditions
in one place and then dispatches the individual timer functions.
