If WMM is not disabled explicitly (wmm_enabled=0 in hostapd.conf),
enable WMM automatically whenever HT (ieee80211n) is enabled. Use
the default WMM parameters for AP TX queues and the EDCA parameters
advertised for stations in WMM IE if no overriding values are
included in the configuration.
In theory, this should not really be needed, but Windows 7 uses
Registrar mode to probe AP's WPS capabilities before trying to use
Enrollee and fails if the AP does not allow that probing to happen.
This allows the AP to start as an Enrollee and send M1, but refuse
to continue beyond that (M3 will not be sent if AP PIN is not known).
wmm_ac_??_cw{min,max} parameters are in log form
When the wme_ac_??_cw{min,max} parameters aren't specified in
hostapd.conf, hostapd uses an incorrect set of default values, as the
defaults are in 2^x-1 form instead of in log form. This patch changes
them over to the expected log form.
Doxygen and some build tools may get a bit confused about same file
name being used in different directories. Clean this up a bit by
renaming some of the duplicated file names in src/ap.
