💅 ice_xdp_rx_hw_ts(9)

okay so bestie, welcome to the Kernel API Manual — yes we're literally in the kernel docs rn and it's giving main character energy ✨ this one's a tiny lil function page but it's iconic in its own way, trust 🫶

✨ NAME ✨

ice_xdp_rx_hw_ts — the HW timestamp XDP hint handler 👑 like, it's the go-to girly for handing you the hardware timestamp when XDP asks for it

🌸 SYNOPSIS 🌸

int ice_xdp_rx_hw_ts (const struct xdp_md *ctx , u64 *ts_ns );

that's the whole vibe, no cap — one call, two args, int coming back at ya 💖

🎀 ARGUMENTS 🎀

  • ctx — the XDP buff pointer 💅 so like, the XDP buffer itself, that's what you're passing in here
  • ts_ns — the destination address 🎯 where the timestamp's gonna land, you're literally handing it the drop spot

🦋 DESCRIPTION 🦋

okay so the whole thing: it copies the HW timestamp over to the destination address — but only if it's available 🙈 like if the hardware timestamp isn't there, don't come for her, she's not gonna conjure one out of thin air, that's just how it is 💀

so yes: HW timestamp (if available) → the destination address. slay, that's the function. short and iconic, periodt ✨

ngl bestie, the "(if available)" part is doing a lot of heavy lifting here — no timestamp available means no copy, so don't assume you always get one 🫶
