Subject: [PATCH AUTOSEL 6.6 23/51] wifi: mac80211: set station RX-NSS on reconfig

From: Johannes Berg <johannes.berg@...el.com>

[ Upstream commit dd6c064cfc3fc18d871107c6f5db8837e88572e4 ]

When a station is added/reconfigured by userspace, e.g. a TDLS
peer or a SoftAP client STA, rx_nss is currently not always set,
so that it might be left zero. Set it up properly.
