Re: LinuxKPI (iwlwifi, rtw8x) Please test! Important! (also in stable/15 now)

Hi,

I am a bit behind, but rtw89 works with these changes in stable.

Only issue I have (not cause by these changes, already started a few 
weeks ago, but I forgot to report it):

On bootup i get:

wlan0: link state changed to UP
wlan0: link state changed to DOWN
rtw890: lkpi_sta_a_to_a:3325: lvif 0xfffffe00d3dd1000 vap 
0xfffffe00d3dd1010 iv_bss 0xfffffe00cc1c0000 lvif_bss 0xfffff8001f5ea00
0 lvif_bss->ni 0xfffffe0121674000 synched 0
rtw890: lkpi_iv_newstate: error 95 during state transition 2 (AUTH) -> 2 
(AUTH)
wlan0: link state changed to UP
wlan0: link state changed to DOWN
rtw890: lkpi_sta_a_to_a:3325: lvif 0xfffffe00d3dd1000 vap 
0xfffffe00d3dd1010 iv_bss 0xfffffe0120887000 lvif_bss 0xfffff8002c21f00
0 lvif_bss->ni 0xfffffe00cc1c0000 synched 0
rtw890: lkpi_iv_newstate: error 95 during state transition 2 (AUTH) -> 2 
(AUTH)
wlan0: link state changed to UP

Which takes a few seconds, but afterwards it works just fine.
