To support TX diversity, query firmware to know if it is 1T2R variant model. Then, checking RSSI periodically to know which antenna has better signal strength that can be seen as the antenna is close to AP. Therefore, use the antenna with better RSSI to transmit packets dynamically. v2: - patch 3/5: use separate 'ret' - patch 5/5: no need casting from void pointer Ping-Ke Shih (5): wifi: rtw89: use u32_get_bits to access C2H content of PHY capability wifi: rtw89: parse phycap of TX/RX antenna number wifi: rtw89: configure TX path via H2C command wifi: rtw89: record signal strength per RF path wifi: rtw89: support TX diversity for 1T2R chipset drivers/net/wireless/realtek/rtw89/core.c | 21 +++++-- drivers/net/wireless/realtek/rtw89/core.h | 6 +- drivers/net/wireless/realtek/rtw89/debug.c | 12 +++- drivers/net/wireless/realtek/rtw89/fw.c | 62 ++++++++++++++++--- drivers/net/wireless/realtek/rtw89/fw.h | 43 ++++++++----- drivers/net/wireless/realtek/rtw89/mac.c | 35 ++++++++--- drivers/net/wireless/realtek/rtw89/mac80211.c | 3 +- drivers/net/wireless/realtek/rtw89/phy.c | 56 +++++++++++++++++ drivers/net/wireless/realtek/rtw89/phy.h | 1 + drivers/net/wireless/realtek/rtw89/reg.h | 6 ++ drivers/net/wireless/realtek/rtw89/rtw8852a.c | 6 +- drivers/net/wireless/realtek/rtw89/rtw8852c.c | 6 +- 12 files changed, 211 insertions(+), 46 deletions(-) -- 2.25.1
