Add support for MAC/pause/RMON stats. This enables reporting hardware
statistics in a common way via:

ethtool -S eth0 --all-groups
and
ethtool --include-statistics --show-pause eth0

While doing so, add support for one new stat, receive length error
(RLEC), which is extremely unlikely to happen since most L2 frames have
a type/length field specifying a "type", and raw ethernet frames aren't
used much any longer.

NOTE: I didn't implement Ctrl aka control frame stats because the
hardware doesn't seem to implement support.
