[PATCH net-next 0/7] bng_en: add link management and statistics support

[Bhargava Marreddy]

Hi,

This series enhances the bng_en driver by adding:
1. Link/PHY support
   a. Link query
   b. Async Link events
   c. Ethtool link set/get functionality
2. Hardware statistics reporting via ethtool -S

This version incorporates feedback received prior to splitting the
original series into two parts. 

 Addressed following comments from Andrew Lunn
   - Apply Rev-xmas fix in several places.
   - Correct ethtool-speed comment to reflect accurate behavior.
