Subject: [PATCH] Wifi HAL SIOCSIFHWADDR sepolicy
Add sepolicy rule to grant Wifi HAL permission to use SIOCSIFHWADDR
ioctl. This permission is needed to dynamically change MAC address of
the device.
We are moving the implementation of setting the MAC address from
WifiCond to Vendor HAL to give vendors flexibility in supporting
Connected MAC Randomization. Will clean up WifiCond sepolicy afterwards.
Bug: 74347653
Test: Verified manually
