(In reply to Robert Clausecker from comment #6)
Robert, can you post the ath0 section from the output of "pciconf -v"? The
original reporter, myself and the referenced GhostBSD issue all appear to have
Dell (subvendor 0x1028) Wireless 1601/1901 devices with subdevice ID 0x020d.
The card does not have any special .driver_data hints in either FreeBSD
(https://cgit.freebsd.org/src/tree/sys/dev/ath/if_ath_pci_devlist.h) or Linux
(e.g.
https://github.com/torvalds/linux/blob/master/drivers/net/wireless/ath/ath9k/pci.c),
but the card works fine under Linux. My mostly-uneducated guess is that FreeBSD
is missing a workaround or initialization step for the HAL that is present in
Linux that leads to the symptoms of a bogus MAC address and nonfunctional
scanning.
