These cards are 2.4G only so any code of which you are sure it is for 5G only can be removed. > - find and remove any code for other chips that is left over > > Ok this seems clear, are there some suggestion to do it safely?

I know that "youling 257 <youling257@xxxxxxxxx>" is using a different version of the original (out-of-tree, non cleaned-up) Realtek driver code for the Android-X86 kernels he works on. You should probably ask youling why that version is being used and try to get a copy of the original Realtek sources on which the staging driver is based and do a "diff -ur" between them and see what is different. > - switch to use LIB80211 > - switch to use MAC80211 > > I think I need a few details for these last points as well. I'm afraid I cannot help there, you should ask for help with this on the linux wireless email list. > Do you think that one will need real hardware to complete > these tasks?

Yes you really do need hardware, even simple coding style cleanups are known to (accidentally) break driver functionality, so you really should ensure that you are capable of testing your changes on real hardware.
