Subject: - Add Intel firmwares for Intel PRO/Wireless LAN 2100/2200/2915 cards
 in a uuencoded format along with their respective LICENSE files. - Add new
 share/doc/legal directory to BSD.usr.dist mtree file. This is the place we
 install LICENSE files for restricted firmwares. - Teach firmware(9) and
 kmod.mk about licensed firmwares. Restricted firmwares won't load properly
 unless legal.<name>.license_ack is set to 1, either via kenv(1) or
 /boot/loader.conf.
