[ath9k-devel] [PATCH] ath9k_htc: add STBC TX support
current firmware will enable STBC_TX, only if other peer support it.
This patch provide ht_peer_caps to firmware.
FW versions 1.3, 1.4 should be able to work with it.
Tested on ar7010+ar9280 and ar7010+ar9287.
- v2. Use one bit instead of two for RX STBC flags.
- v3. Use ATH_RC_*_STBC_FLAG instead of WLAN_RC_RX_STBC_FLAG
