routines and thus assert if one passes in a rate code with the
high bit set.
Since the high bit can indicate either IEEE80211_RATE_BASIC or
IEEE80211_RATE_MCS, it's up to the caller to determine whether
the rate is 11n or not, and either mask out the BASIC bit, or
call a different function.
(Yes, this does mean that net80211 should grow 11n-aware rate2phytype()
and rate2plcp() functions..)
This may need to happen for the other drivers - it's currently only
done (now) for iwn(4) and bwi(4).

Broadcom BCM43xx chipsets. This driver uses the v3 firmware that
needs to be fetched separately. A port will be committed to create
the bwi firmware module.
The driver matches the following chips: Broadcom BCM4301, BCM4307,
BCM4306, BCM4309, BCM4311, BCM4312, BCM4318, BCM4319
The driver works for 802.11b and 802.11g.
Limitations:
This doesn't support the 802.11a or 802.11n portion of radios.
Some BCM4306 and BCM4309 cards don't work with Channel 1, 2 or 3.
Documenation for this firmware is reverse engineered from
http://bcm.sipsolutions.net/
V4 of the firmware is needed for 11a or 11n support
http://bcm-v4.sipsolutions.net/
Firmware needs to be fetched from a third party, port to be committed
# I've tested this with a BCM4319 mini-pci and a BCM4318 CardBus card, and
# not connected it to the build until the firmware port is committed.
