Subject: [PATCH] mac80211: propagate HE operation info into bss_conf
Git-commit: 697f6c507c74991057eb6df3cfb46579ca136467
Patch-mainline: v5.4-rc1
References: jsc#SLE-13430
Upon a successful assoc a station shall store the content of the HE
operation element inside bss_conf so that the driver can setup the
hardware accordingly.
