== Others ==

For some hints on other value controllable with iwpriv, see the source files [source:madwifi/trunk/net80211/ieee80211_ioctl.h net80211/ieee80211_ioctl.h] around line 550 and [source:madwifi/trunk/net80211/ieee80211_wireless.c net80211/ieee80211_wireless.c] around line 5000.  There are short descriptions in the comments.  Perhaps someone can transfer this cleanly to the wiki.
