Import the most recent versions of the firmware images for the rtw88 driver. This is based on linux-firmware at 681281e49fb6778831370e5d94e6e1d97f0752d6. The license of the firmware matches the previous rtwnfw(4) firmware files (modulo a Copyright year) and you can find a copy in sys/contrib/dev/rtw88fw/LICENCE.rtlwifi_firmware.txt. Add build infrastructure to create the .ko files but do not yet hook it up to the build until all parts are in the tree. Approved by: core (imp) MFC after: 2 weeks

rtw88 firmware
|
|
================
|
|
|
|
This repository contains firmware images supported by Realtek's wireless
|
|
driver rtw88. And some of the devices run with more than one firmware
|
|
file. Basically, a "normal" firmware is necessary to be downloaded to
|
|
the device.
|
|
And another is called "wowlan" firmware, it should be loaded when a
|
|
device is going to suspend. Which means driver will "re-download/swap"
|
|
the firmware image. The wowlan firmware contains wake up functions that
|
|
can recognize specific events and send a wake up signal to device if
|
|
needed, and the system will resume to running state. During resume,
|
|
driver will then swap the normal firmware back, return to running state.
|
|
|
|
If any distros or platforms do not require wowlan feature, they can
|
|
_only_ pick the normal firmware. And everything still works fine,
|
|
except that the device cannot be waken from the wireless NICs.
