__phy_ethtoo...nk_ext_stats(9)

💖 NAME 💖

__phy_ethtool_get_link_ext_stats — retrieve extended link statistics for a PHY. Yes bestie, this is from the Kernel API Manual, and the page header truncates the title to __phy_ethtoo...nk_ext_stats(9) because even kernel docs need a little drama. It’s giving “I know all your PHY’s link tea.” 💅

🌸 SYNOPSIS 🌸

void __phy_ethtool_get_link_ext_stats (struct phy_device *phydev , struct ethtool_link_ext_stats *link_stats );

🎀 ARGUMENTS 🎀

• phydev — pointer to the PHY device, aka the main character here.
• link_stats — pointer to the structure that’s gonna store the extended link statistics.

🦋 DESCRIPTION 🦋

Okay so what this function does is populate the ethtool_link_ext_stats structure with link down event counts and additional driver-specific link statistics, if available. That’s literally the whole vibe: it’s a void, so it doesn’t hand anything back — it just fills up link_stats with the link-down receipts plus any extra driver-specific stats the driver can offer. ✨

And that’s the page, bestie 🎀 it lives under the source path ./drivers/net/phy, dated October 2026, and it’s part of the Kernel API Manual. The footer also calls it __phy_ethtoo...nk_ext_stats(9) because consistency is cute. Slay. 💜
