When working on the WPA-Enterprise stuff, I actually ran into an issue
with the rsu(4) I was using. It seems there is a problem with
submitting the "join BSS" command when an RSN information element is
included, which makes the command never complete. The crucial bit
seems to be that this changes the length of the command to something
the firmware doesn't like. The code rounds the length up to the next
multiple of 8, but it seems the firmware wants it to be at least a
multiple of 16. The easiest fix seems to be to just send the entire
buffer that we allocate for the command. This will transfer more
bytes than strictly necessary, but this command isn't sent invoked
very often so I don't think this will be a problem. This diff might
fix issues with WPA-PSK as well.
ok?
