Just one comment...

You'll need to emit more NULL IWAP events on association failure.  For
example, gelic_wl_assoc_worker() should probably send one right before
both instances of 'goto scan_lock_out' in that function (the first where
there are no scan results, and the second where no compatible BSS can be
found).  Also, gelic_wl_associate_bss() needs to send a disassociation
event in the failure case where it sets GELIC_WL_ASSOC_STAT_DISCONN.

Other than that, looks pretty good to me.  You might want to run
checkpatch.pl over it before submitting again just to be sure.  Thanks
for fixing the WPA IE and scan table handling!
