>Description:
The D-Link DWL-530 wireless card uses the Atheros 5212 chip, but the ATH driver is unable to reset the chip during hardware initialization; the card is therefore unusable.

Relevant output from dmesg:
portroyal# dmesg | grep ath0
ath0: <Atheros 5212> mem 0xe9000000-0xe900ffff at device 15.0 on pci0
ath0: Ethernet address: 00:13:46:9a:28:5c
ath0: mac 5.9 phy 4.3 radio 3.6
ath0: ath_chan_set: unable to reset channel 5 (2432 Mhz, flags 0x3e0 hal flags 0x140)
ath0: unable to reset hardware; hal status 12
ath0: unable to reset hardware; hal status 12
ath0: unable to reset hardware; hal status 12

>From the ATH driver page:
     ath%d: ath_chan_set: unable to reset channel %u (%u Mhz)  The Atheros
     Hardware Access Layer was unable to reset the hardware when switching
     channels during scanning.  This should not happen.
     ...
     ath%d: unable to reset hardware; hal status %u  The Atheros Hardware
     Access Layer was unable to reset the hardware as requested.  The status
     code is explained in the HAL include file sys/contrib/dev/ath/ah.h.  This
     should not happen.

>How-To-Repeat:
