This patch adds support for reporting statistics on the operation of the
rate control modules via /proc. Currently on the sample rate module
actually provides any statistics.
This patch uses the new VAP proc entry support provided by ticket #728 to
manage the proc entries. It must not be applied until after the patch from
ticket #728 has been committed.
The statistics reported for the sample module were present in the madwifi-
old module but did not seem to make it into madwifi-ng. I have made some
minor changes to how these statistics are reported:
1. Statistics are now reported via /proc entries instead of using
sysctls. Sysctls are intended as a method for the user to configure
parameters of the module and should not be misued for reporting
statistics.
1. A new symbol ''ath_rate_dynamic_proc_register'' is exported from each
rate control module. This function is called by the driver just after a
new VAP has been created to allow the rate control module to register the
appropriate proc entries. As described in ticket #728, all further
management of these entries will be handled by the VAP, which will call
the functions supplied by the rate control module to retrieve data when
necessary.
The information that this patch adds back into the driver is very useful
and is referred to in the documentation at wiki:UserDocs/RateControl which
currently causes some confusion when the statistics is not found. The
aforementioned page should be updated to reflect that the statistics will
now live at /proc/net/madwifi/<ifname>/ratestats_{250,1600,3000} after
this patch is applied.
Please apply this patch after you have committed the patch in ticket #728.
