Just wondering: Is this a good approach? What firmware should distros
pick? Is there a trade-off affecting other wifi functionality when using
WoW firmware?
If distros want to use WOW, they should pick both.
For Realtek devices such as RTL8822CE, it needs to "change/re-download"
the wow firmware to suspend with WOW functionalities. When resume,
switch back to normal firmware to run "normally".
I think the reason is the firmware size restriction. For newer devices,
maybe there is a larger space for firmware, and we don't need to swap
the FW like this :)
Interesting approach and I would mention this in the commit message or
add a README in rtw88 folder explaining it. Not sure whether distros
look at commit messages.
