The following is a discussion I had on the freebsd-questions list. I've
decided to take the route of buying an adapter that works on FreeBSD 10
Release but, on suggestion, I thought I would ask on these lists if
there was anywhere I could mail my useless (to me) adapter so support
could be added.

I applied the patches manually and had some mixed success.
I can see the device and it registers as ue0. unfortunetly, it doesn't
completely work.
When I plug it in, the console displays:
ugen4.2: <Linksys> at usbus4
cdce0: <Linksys Linksys USB3GIGV1, class 0/0, rev 2.10/30.00, adds 2> on
usbus4
cdce0: faking MAC address
ue0: <USB Ethernet> on cdce0
ue0: Ethernet address: 2a:d5:07:9d:01:00
The output from 'ifconfig ue0':
ue0: flags=3D8802<BROADCAST,SIMPLEX,MULTICAST> metric 0 MTU 1500
ether 2a:d5:07:9d:01:00
nd6 options=3D29<PREFORMNUD,IFDISABLED,AUTO_LINKLOCAL>
Notably lacking a media or status entry.
Is there any where I can go from here or should I wrote off this adapter
and find a replacement?
