Revert "mac80211: Use IWEVASSOCREQIE instead of IWEVCUSTOM"
This reverts commit 087d833e5a9f67ba933cb32eaf5a2279c1a5b47c, which was reported to break wireless at least in some combinations with 32bit user space and a 64bit kernel. Alex Williamnson bisected it to this commit. Reported-and-bisected-by: Alex Williamson <alex.williamson@hp.com> Acked-by: John W.
