> Subject: [Intel-wired-lan] [PATCH iwl-next v4 2/2] ixgbe: add link_down_events statistic
>
> Introduce a link_down_events counter to the ixgbe driver, incremented each time the link transitions from up to down.
> This counter can help diagnose issues related to link stability, such as port flapping or unexpected link drops.
>
> The value is exposed via ethtool's get_link_ext_stats() interface.
