So, with the updated HAL, I'm now able to negotiate an IP address via DHCP
over the WLAN. Huzzah!
But I've got two questions (now that I can use the card):
ath(4) doesn't contain a list of media nor mediaopt settings that can be
used. Some are detailed down in EXAMPLES, but there's no comprehensive
list. (As well, and this is minor, the speeds are explicitly listed for
802.11a and 802.11b, but just labelled as 'appropriate' transmit speeds for
802.11g. 'Twould be nice to have them all uniformly listed.)
Secondly, I was under the impression that 802.11g could support up to
54Mbps. Does FreeBSD not provide support for speeds that fast (ISTR it did
at one point)?
# ifconfig ath0
ath0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500

Any reason I can't bring it up to 54Mbps? Hardware indicates it should
actually support it:
ath_hal: 0.9.16.16 (AR5210, AR5211, AR5212, RF5111, RF5112, RF2413, RF5413)
