[PATCH 0/2] Add ability to configure ethernet h/w shaper

[Ivan Khoronzhuk <ivan.khoronzhuk@linaro.org>]

These two patches can be used to set per queue bandwidth with ethtool.
I've create them as logical continuation of patchset from intel,
that have introduced per-queue setting command month ago for ethtool
interface
(http://kernel.opensuse.org/cgit/kernel-source/commit/?h=rpm-4.4.9-36&
id=feaab26abfffe381fb4c8c10d2762a753d481c6c). Actually I've not tested this
interface and planning to send it in parallel with
"net: ethernet: ti: cpsw: add multi-queue support"
(https://lkml.org/lkml/2016/6/30/603), as it contains only changes to
ethtool interface.

First patch can be used to set per-channel bandwidth, second to tune
number of per-channel descriptors. It can solve issues described by
Schuyler. In case if per-channel bandwidth is equal to maximum
for every channel, the driver could be switched to priority mode.
