Re: iwlwifi/LinuxKPI 802.11 update

Hi Kzrysztof,

Thanks for your report.
Because I use 13 stable and cannot test the current,
your report is very useful to me.
I'm using ThinkPad X1 nano which has a AX201.

I have some questions.

Do we need the 'if_iwlwifi_load="YES"' line
in addition to the  'kld_list=if_iwlfiwi' line?
I don't think so, but I may be wrong.

Do you use "wifimgr" which is a GUI tool to select AP.
When I use "if_iwlfiwi.ko", wave strength displayed
in wifimgr is 0 for all access point.
Do you see this phenomenon? Or, does someone see this?

Best,
Takashi
