Bug 21967

Wireless ethernet cards often require a substantial number of settings
to be configured before they can attach to a network.  FreeBSD provides
no automated machanism to do this.  Additionaly, these settings may vary
from one environment to another such as home, office, and public areas
such as airport terminals.

Fix: Apply the following patch.  This patch provides generic hooks for
interface configuration prior to ifconfig derived from those submitted
by Danny Howard <dannyman@tellme.com> in PR:conf/21489.  The
config_802.11 script tries configrations until one that works is found.
I believe the set of defaults I provide will not break existing setups
and will automaticaly enable access to unrestricted access points.
Aironet configuration depends on Doug Ambrisko's WEP patches submitted
in PR:kern/21864 and the Lucent configuration may require the patches in
PR:bin/21803 in certain rare cases.

This is a work in progress, but it works well enough that I'd like to
see it get wider exposure.  Until this or a similar facility is
commited, I will perodicaly update a copy of the patch at:

How-To-Repeat: 
Try using a wireless ethernet card with an access point with security
settings enabled.
