[Madwifi-devel] How to Read MIB Counters Stats?

[Tsung C. W. <tw...@br...>]

Dear All,

I am currently starting on a project to try extract all the counters defined
in the MIB (e.g. RTS_Success_Count, ACK_Failure_Count, FCS_Error_Count, and
so on).
I am very new to developing drivers so please bear with me!

I can see that in ah.h, HAL_MIB_STATS struct can be found and I reckon that
I will have to use ath_hal_attach function to obtain those statistics. Then
use iwpriv function to present the statistics, this done by modifying the
code in if_ieee80211wireless.c.
Can it be done this way? Can I also extract more counter values than the
ones stated in HAL_MIB_STATS, like those stated in the standard802dot11 MIB?

I have noticed that in if_wavelan_ieee.h, that wi_counters struct is being
defined having all the desired counters. Does this mean that both Atheros
and WaveLAN chipset supports the extraction of these counters? If so, how
can they be extracted?

Thank you for your patience!
