Subject: [PATCH 2/2] brcmfmac: correctly report average RSSI in station info
Date: Thu, 6 May 2021 13:20:12 +0000	[thread overview]
Message-ID: <20210506132010.3964484-2-alsi@bang-olufsen.dk> (raw)
In-Reply-To: <20210506132010.3964484-1-alsi@bang-olufsen.dk>

The rx_lastpkt_rssi field provided by the firmware is suitable for
NL80211_STA_INFO_{SIGNAL,CHAIN_SIGNAL}, while the rssi field is an
average. Fix up the assignments and set the correct STA_INFO bits. This
lets userspace know that the average RSSI is part of the station info.

Signed-off-by: Alvin Šipraga <alsi@bang-olufsen.dk>
Fixes: cae355dc90db ("brcmfmac: Add RSSI information to get_station.")
