Merge branch 'MTU-core-range-checking-more'
Jarod Wilson says:
====================
net: use core MTU range checking everywhere
This stack of patches should get absolutely everything in the kernel
converted from doing their own MTU range checking to the core MTU range
checking. This second spin includes alterations to hopefully fix all
concerns raised with the first, as well as including some additional
changes to drivers and infrastructure where I completely missed necessary
updates.
These have all been built through the 0-day build infrastructure via the
(rebasing) master branch at https://github.com/jarodwilson/linux-muck, which
at the time of the most recent compile across 147 configs, was based on
net-next at commit 7b1536ef0aa0.
