BugLink: http://bugs.launchpad.net/bugs/1201321

Adding support of model RTL8411B. Since the model is similar to RTL8411,
differences are implemented in rtl8411.c.

This will appear in the Saucy unstable branch (if its not there already)
when we rebase against 3.11-rc1. Soon thereafter (by about -rc3) we'll
switch to v3.11 as the primary archive kernel.
