>Originator: William R. Somsky
>Release: FreeBSD 3.1-STABLE i386
>Organization:
University of Washington, Department of Physics
>Environment:
Workstations in a DHCP environment with fixed (not PCMCIA/removable)
ethernet cards.
>Description:
In some instances, it is desireable to have a workstation with
fixed (not PCMCIA/removable) ethernet cards to use DHCP for its
interface configuration. This patch allows an entry of
ifconfig_<ifn>="DHCP"
in the rc.conf file to mark the interface to be configured
via DHCP and to do so upon system booting.
>How-To-Repeat:
>Fix:
This patch takes the code for starting DHCP from etc/pccard_ether,
and places a copy of it, with appropriate "if"'s into rc.network.
Once this patch is installed, an interface such as xl0 may be
configured using DHCP by putting ifconfig_xl0="DHCP" in the
rc.conf file.
