====================
net: macb: various cleanups

Fix many oddities inside the MACB driver. They accumulated in my
work-in-progress branch while working on MACB/GEM EyeQ5 support.

Part of this series has been seen on the lkml in March then June.
See below for a semblance of a changelog.

The initial goal was to post them alongside EyeQ5 support, but that
makes for too big of a series. It'll come afterwards, with new
features (interrupt coalescing, ethtool .set_channels() and XDP mostly).
