[iwl-next,v2,0/2] Add link_down_events counters to ixgbe and ice drivers

Message

Szapar-Mudlaw, Martyna April 14, 2025, 1 p.m. UTC

This series introduces link_down_events counters to the ixgbe and ice drivers.
The counters are incremented each time the link transitions from up to down,
allowing better diagnosis of link stability issues such as port flapping or
unexpected link drops.

The values are exposed via ethtool using the get_link_ext_stats() interface.

  ice: add link_down_events statistic
  ixgbe: add link_down_events statistic

v2 -> v1:
used ethtool get_link_ext_stats() interface to expose counters
