net: mana: Expose additional hardware counters for drop and TC via ethtool.
Add support for reporting additional hardware counters for drop and
TC using the ethtool -S interface.
These counters include:
- Aggregate Rx/Tx drop counters
- Per-TC Rx/Tx packet counters
- Per-TC Rx/Tx byte counters
- Per-TC Rx/Tx pause frame counters
The counters are exposed using ethtool_ops->get_ethtool_stats and
ethtool_ops->get_strings. This feature/counters are not available
to all versions of hardware.
