CVS commit: src/sys/net

[David Young <dyoung%netbsd.org@localhost>]

Module Name:    src
Committed By:   dyoung
Date:           Fri Aug 24 23:38:32 UTC 2007

Modified Files:
        src/sys/net: if_gre.c if_gre.h

Log Message:
Overhaul gre(4), especially the GRE in UDP bits:

* Create the kernel thread in gre_clone_create() instead of trying
  to create it in gre_ioctl().  (Thanks ad@ for suggesting it, and
  pointing out that I can't kthread_create while I hold a spin
  lock.)  Run the thread always, but put it to sleep while the
  gre(4) is not in UDP mode.

* Use sockaddr_in_init().

* Move some thread state off of the stack and into the softc.

* Extract subroutines gre_do_recv(), gre_do_send(), and gre_reconf()
  from gre_thread1(), making the code more readable.
