>Description:

The atu(4) driver is unable to communicate with an 802.11b base
station configured to use WEP encryption.

>How-To-Repeat:

Connect a USB 802.11b adapter supported by the atu(4) driver.
I used a TRENDnet TEW-229UB.  Confirm that it works without WEP.

Configure the base station with a WEP key, say,
0xaaaaaaaaaaaaaaaaaaaaaaaaaa, and configure the
same key on the atu device:

  ifconfig atu0 nwkey 0xaaaaaaaaaaaaaaaaaaaaaaaaaa

Notice that the connection no longer works.

>Fix:

Unknown.  It looks like the code to support WEP in if_atu.c is
incomplete; for example, there is a function atu_set_wepkey() but
it is never called.
