Great for testing!  Thank you very much!  Will help merging this for tomorrow.

No, they will only go away when we cleaned up net80211 so I am not trying to
work around more and more currently in LinuxKPI.  It's going to be focusing
on bringing net80211 into the 2026s.

Yes.  I've head a branch (not upstreamable) which did have RX and TX on par.
There's more work to be done to get RX behave and also to eliminate the
semi-excessive queue lengths currently employed in LinuxKPI.  Again some
net80211 improvements will help this.

That said your speeds will be highyl dependend on location, radio enviroment,
access point, orientation of your laptop.  I could notice people walking in
the room the other day while running a backup over wifi as ethernet was limited
to 100Mbit/s and wifi simply was faster and I kept watching the
compat.linuxkpi.80211.waln0 sysctl information.

That said I wouldn't say no to getting 1 Gbit/s going again either...
