💅 sis900_finish_xmit 💅

okay so bestie, welcome to the sis900_finish_xmit page in the Kernel API Manual — yes that's the manual name, drop it in your notes 📝 — and no cap, this one is short but it's important, so pay attention 🫶

✨ NAME ✨

sis900_finish_xmit — finish up transmission of packets 🎀

Like, the cleanup era. The "okay we sent the thing, now let's tidy up" moment. Slay.

🌸 SYNOPSIS 🌸

void sis900_finish_xmit (struct net_device *net_dev );

that's the whole signature, exactly like that, don't come for me about the spacing, I copied it character for character 💅

🦋 ARGUMENTS 🦋

  • net_dev — the net device to be transmitted on 🫶 the actual interface this whole transmission situation is happening on

💖 DESCRIPTION 💖

okay so here's the vibe: this function checks for error conditions, and then it frees the socket buffer and all that other housekeeping, and it schedules more transmission as needed ✨

literally the "check the vibes, clean up the mess, and line up the next round" function. it's giving main character energy of the TX path, ngl 🎀

💀 NOTE 💀

this function is called by the interrupt handler, so bestie — don't do "too much" work here 😭 like, keep it light. interrupt context is NOT the place for a whole side quest. 🙈

fr fr, that's a real caveat, don't skip it.
