mac80211: update injection documentation
We don't currently support antenna or rate setting, so remove that. Also update the link -- the current one is dead and the wiki can be kept updated easier. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
