CVS commit: src/sys/net

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

Module Name:    src
Committed By:   dyoung
Date:           Tue Jan 22 16:25:16 UTC 2008

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

Log Message:
Take two steps toward adding and deleting link-layer addresses.

1 Extract subroutine if_dl_create() from if_alloc_sadl().
  if_dl_create() allocates a link-layer ifaddr.

2 Extract subroutine ifioctl_common() from ifioctl().  ifioctl_common()
  will be the basis for an ifnet "superclass" whose functions
  drivers may inherit.  Very simple drivers may set ifnet->if_ioctl
  = ifioctl_common.  More sophisticated drivers will set ifnet->if_ioctl
  = driver_ioctl.  driver_ioctl() will call ifioctl_common() to
  re-use the common code.
