After commit 9a1590934d9a ("brcmfmac: correctly report average RSSI in
station info") it is required from firmware to provide rx_lastpkt_rssi.
If this field is not provided brcmfmac doesn't report any RSSI at all.
Unfortunately some firmwares doesn't provide it. One example is firmware
for BCM43455 found in Raspbberry Pi.
See https://github.com/raspberrypi/linux/issues/4574
Fix it by falling back to rssi field if rx_lastpkt_rssi is not provided
(like it was before 9a1590934d9a).
Sounds like a reasonable approach. However, I would like to learn more
about the issue. Maybe it is a per-vendor issue so I am interested what
the sta_info version is that we get from firmware. It is printed in
brcmf_cfg80211_get_station() with brcmf_dbg(). You can make it a
bphy_err() call instead or enable TRACE level debug messages in the driver.
Also would be good to know the firmware version and kernel version of
the BCM43455.

Hi Arend,
Is the info I have provided sufficient?
I am missing the kernel version and whether it is upstream kernel or not.
