[PATCH] mac80211: improved 802.11g CTS protection
Currently, CTS protection is partially implemented twice:
1. via prism2 ioctls, only used by hostapd
2. via STA beacon parsing, recorded in sta.use_protection but never used
(other than printed in debugfs)
Protection control should be implemented on a per-subif basis. For example,
a single physical device may be running a soft AP on one channel, and a STA
on another. The AP interface should use protection based on what hostapd told
it, and the STA interface should use protection based on beacon parsing.
These should operate independantly: one subif using protection should not
influence the other.
To implement this, I moved the use_protection flag into ieee80211_sub_if_data
and removed the device-global cts_protect_erp_frames flag.
I also made the PRISM2_PARAM_CTS_PROTECT_ERP_FRAMES write operation only
available for AP interfaces, to avoid any possibility of the user messing with
the behaviour of a STA.
