Subject: wifi: rtw89: fw: add CMAC H2C command for TX time for RTL8922D
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=eccf7b10785b7e9b32b5a7fcbf1f45b6db9a5ac5;p=thirdparty%2Fkernel%2Flinux.git

wifi: rtw89: fw: add CMAC H2C command for TX time for RTL8922D

CMAC H2C command is to configure CMAC such as TX retry and padding. Add to
update CMAC function block when BT-coex want shorter TX time due to
timeslot assignment, or when MCC want higher retry time to improve
connection rate.
