   Thomas, would you try attached patch on your system?

Which version/branch of FreeBSD is this for?  

9.2_STABLE, 10-stable or 11-head?

Does it require a specific svn revision?

I just updated FreeBSD-current on new MSI motherboard (svn revision 257695).

dhclient re0 still gives same error.

Now I have to update FreeBSD-current amd64 on same computer.

I go through this in the hope of being able to configure wifi with Hiro 50191 USB-stick-type WLAN adapter, driver rsu.

So far, can't see wifi network.  I see what more I need to do, or maybe no wifi signal?
