AR_RxKeyIdxValid will not be set for bcast/mcast frames and so relying

Due to this, MIC failure events for broadcast frames are not sent to
supplicant resulted in AP disconnecting the STA.

Able to pass Wifi Test case 5.2.18 with this fix.

Please do not apply this yet.  As far as I can tell, either
of these patches breaks multiple VIF scenarios.  I'm not
sure exactly why, but I had to revert this to get any
of my interfaces to associate.

Ben can you please give some more information(or just point out some
link) regarding your test case,I can try it out.
thanks,

Try this script, or something like it:

Edit 'max' to create a small number of STA interfaces or you will probably
have
worse issues than them just not associating!

You have to enable the nohwcrypt module option.

Let me know if that doesn't work and I can probably put together something
more specific.

thanks Ben.

Were you able to reproduce the problem?

Thanks,
Ben



Thanks,
Ben
