Subject: [PATCH 0/6] wifi: rtw89: generalize MAC registers to support WiFi 7 chips

WiFi 7 registers of RTS, MU-EDCA and beamforming are different from
existing chips, but we can still possibly reuse most of existing code.
The initial beamformee code when associated is largely different, so make
them as individual functions.

Ping-Ke Shih (1):
wifi: rtw89: mac: add registers of MU-EDCA parameters for WiFi 7 chips

Zong-Zhe Yang (5):
wifi: rtw89: mac: update RTS threshold according to chip gen
wifi: rtw89: mac: generalize register of MU-EDCA switch according to
chip gen
wifi: rtw89: mac: set bfee_ctrl() according to chip gen
wifi: rtw89: mac: set bf_assoc capabilities according to chip gen
wifi: rtw89: mac: do bf_monitor only if WiFi 6 chips

Subject: [PATCH 4/6] wifi: rtw89: mac: set bfee_ctrl() according to chip gen

From: Zong-Zhe Yang <[email protected]>

When associated peer has beamformer capability, enable hardware beamformee
function, and then hardware can run sounding protocol itself. Oppositely,
disable this function when disassociated. Define different registers for
WiFi 6 and 7 generations respectively.

Since WiFi 7 registers are very different from WiFi 7, separate
