Subject: wifi: rtw89: add new H2C command to pause/sleep transmitting by MAC ID
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=c313c31ff40d6fe65570eaf237c8ba4428aeace6;p=linux.git

wifi: rtw89: add new H2C command to pause/sleep transmitting by MAC ID

New H2C command is introduced to pause/sleep transmitting. That extends
more bits to support more MAC ID, and currently we still configure 256
MAC ID at most.

This new command is always used by coming WiFi 7 chips, and existing
chips can use old or new command because firmware still preserves the old
one. Add a firmware feature flag to determine which command is adopted
according to firmware version.
