CVS commit: src/sys/netinet

[Jason R Thorpe <thorpej%netbsd.org@localhost>]

Module Name:    src
Committed By:   thorpej
Date:           Wed Oct 22 02:45:57 UTC 2003

Modified Files:
        src/sys/netinet: tcp_subr.c tcp_usrreq.c tcp_var.h

Log Message:
Rather than zeroing a tcpcb structure and filling in all the fields
individually, create a tcpcb template pre-initialized (and pre-zero'd)
with the static and mostly-static tcpcb parameters.  The template is
now copied into the new tcpcb, which zeros and initializes most of the
tcpcb in one pass.  The template is kept up-to-date as TCP sysctl
variables are changed.

Combined with the previous sb_max change, TCP socket creation is now
25% faster.
