Hi again,
I've made more debugging on my system. I joined to this mail the
modification I've made on my checkout of the wireless-testing git (added
a certain number of 'printk') and the output of: module load, interface
start on a gentoo system (association through wpa_supplicant) and module
unload.
The most interesing lines are, in my opinion, l82-84:
get_highest_rix called, rtlmac->opmode = 2, rtlmac->mode = 0
get_highest_rix called, sta not null, mode 4
BAND_ON_2_4G, mode 0, rf_type == RF_2T2R: 15
First, we are in opmode 2, NL80211_IFTYPE_STATION, which seems normal.
At the same time 'sta' is not NULL. From reading this part of the code,
it seems not to be correct with the opmode, as 'sta' is only read if the
opmode is 1, 3 or 7.
Then, as rtlmac->mode is 0, wireless_mode is set to 0, which is
'WIRELESS_MODE_UNKNOWN' and does not really seems to be right. As a
result, 15 is return as the max rate idx, which will directly cause the
overflow warning at line 89 (the max is 12).
I don't know the code well enough to understand why 'sta' is not null
will it contains the correct mode. I'll try to read more code but though
that you might be interested by this.
Thanks in advance,
Vincent Brillault
