>Description:
Discovered that, with the import of wpa_supplicant 2.0, WEP no longer works
with drivers (iwn for example) if the driver does not declare support for the
WEP cipher.
This should be handled by net80211 in s/w if the h/w and driver do not declare
support for the appropriate cipher.
This is not a bug in iwn(4) but in the way wpa_supplicant attempts to detect
and support h/w that does not have cipher offloading for the requested network.
>How-To-Repeat:
Attempt to use iwn(4) to associate to a WEP network
>Fix:
Use the attached patch (from rpaulo) to declare the cipher's capabilities no
matter what.
thanks to Allan Jude for help in diagnosing this at AsiaBSDCon 2014
