Subject: [v2, net-next 10/12] bng_en: Add initial support for ethtool stats display
This patch adds support for displaying ethtool statistics.
Currently, only the display functionality is implemented.
All stat counters remain at 0, as support for updating the
counters will be added in subsequent patches.
