Thanks for reporting this. The function that updated rx_packets and
rx_bytes was only called in Master mode. I changed the code so that it
will also be called in Repeater mode to get these counters updated.

Well.. It depends. With some cards and some firmware versions that may
indeed be the case, but not with all..

New firmware versions actually give the RSSI -> dBm adjustment value in
cnfDbmAdjust RID. I have only seen value 100 there and the current
driver versions uses fixed 100 (should probably change it to read that
RID and use it, if available). Currently, the numbers are shown as
unsigned integers, but they should probably be converted to be signed
for the procfs files, so you would not need to do this -256 part
