💅 igc_ptp_clear_xsk_tx_tstamp_queue(9) — the Kernel API Manual era 🎀

okay so bestie, welcome to the Kernel API Manual, and today's main character is igc_ptp_clear_xsk_tx_tstamp_queue — yes that's a long name, yes she ate, no we are not shortening it 💅

✨ NAME ✨

igc_ptp_clear_xsk_tx_tstamp_queue — clears out any pending XSK TX timestamps for a queue 🧹✨

Like, she's the cleanup crew. The girl who shows up with a trash bag after the party.

🌸 SYNOPSIS 🌸

void igc_ptp_clear_xsk_tx_tstamp_queue (struct igc_adapter *adapter ,
u16 queue_id );

that's the whole vibe. no return value, she just does the thing and dips 🫶

🦋 ARGUMENTS 🦋

  • adapter — the board private structure 🫶 like, the whole driver's personal diary, lowkey
  • queue_id — the TX queue index whose timestamps we're clearing 🎀 so she knows which queue's mess to clean

🔥 DESCRIPTION 🔥

okay so here's the tea ☕

This function iterates over all the TX timestamp registers and releases any pending timestamp requests that are associated with the given TX queue. Every single register, no skips, no shortcuts — she's thorough, we stan 💜

And when does she get called? When an XDP pool is being disabled — so that no stale timestamp references are left hanging around. It's giving "block him and delete the photos" energy 😭 no stale references, no lingering attachments, periodt.

fr fr she exists so nothing sketchy gets left behind when the pool goes away 🙈
