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.

Addressed following comments from Jakub Kicinski
- Took care of missing mutex_init()

Addressed following comments from ALOK TIWARI
- Add newline for clarity/formatting.

v2:
Addressed comments from Andrew Lunn:
- Add implementation for .get_pauseparam and .set_pauseparam to support
a full flow control configuration, covering global autoneg, independent
pause autoneg, and forced RX/TX pause functionality.
- Move MAC, PHY, Control, Pause, and RMON statistics from
.get_ethtool_stats to their respective structured ethtool
callbacks (e.g., .get_eth_mac_stats, .get_rmon_stats).
Addressed comments from Jakub Kicinski:
- Fix potential out-of-bounds read in speed mask array by adding
the missing sentinel.
- Simplify timer synchronization by removing the redundant intr_sem.
- Replace link_lock with the netdev instance lock, as it is sufficient
to handle the required synchronization.
