Author: adrian Date: Tue Feb 1 03:51:35 2011 New Revision: 218150 URL: http://svn.freebsd.org/changeset/base/218150 Log: Add a new capability which reports the number of spatial streams a device supports. The higher levels (net80211, if_ath, ath_rate) need this to make correct choices about what MCS capabilities to advertise and what MCS rates are able to be TXed. In summary: * AR5416 - 2/3 antennas, 2x2 streams * AR9160 - 2/3 antennas, 2x2 streams * AR9220 - 2 antennas, 2x2 sstraems * AR9280 - 2 antennas, 2x2 streams * AR9285 - 2 antennas but with antenna diversity, 1x1 stream Modified: head/sys/dev/ath/ath_hal/ah.c head/sys/dev/ath/ath_hal/ah.h head/sys/dev/ath/ath_hal/ah_internal.h head/sys/dev/ath/ath_hal/ar5416/ar5416_attach.c head/sys/dev/ath/ath_hal/ar9001/ar9160_attach.c head/sys/dev/ath/ath_hal/ar9002/ar9280_attach.c head/sys/dev/ath/ath_hal/ar9002/ar9285_attach.c Modified: head/sys/dev/ath/ath_hal/ah.c ============================================================================== --- head/sys/dev/ath/ath_hal/ah.c Tue Feb 1 01:05:11 2011 (r218149) +++ head/sys/dev/ath/ath_hal/ah.c Tue Feb 1 03:51:35 2011 (r218150) @@ -583,6 +583,17 @@ ath_hal_getcapability(struct ath_hal *ah return HAL_OK; case HAL_CAP_BSSIDMATCH: /* hardware has disable bssid match */ return pCap->halBssidMatchSupport ?
