Support for Linksys USB3GIG ethernet adapter

[Nicolas Blais]

Has anyone had any luck getting the Linksys USB3GIGv1 USB/Ethernet adapter
to work in FreeBSD? I have no issues in Linux, but it seems currently
unsupported on -CURRENT.  I posted on the forums in Network but was
forwarded here.

On FreeBSD 11-CURRENT (armv6-RPI2):
