Hello Bjoern,

This is a variant of PR 279717.   I need to follow-up there with more

I was running at VHT80 and one single `make distclean fecth` in a go port
will crash wifi.

I'm using `create_args_wlan0="country PT regdomain ETSI mode 11na -vht
-ht160"`
and I did 6 runs on a go port without crash.

Any thoughts or should I try anything else?

Thanks
