zd_mac_tx_failed(9)

💅 zd_mac_tx_failed — callback for failed frames

okay bestie, welcome to the zd_mac_tx_failed(9) page, a lil corner of the Kernel API Manual that's lowkey about what happens when your frame just... doesn't make it 😭 this one lives in the kernel API docs, and it's short but she's important, so let's get into it ✨

✨ SYNOPSIS ✨

void zd_mac_tx_failed (struct urb *urb );

that's it, that's the whole signature, no cap 🫶

🌸 ARGUMENTS 🌸

• urb — a pointer to the urb structure 💖 that's the whole argument list, she's a one-argument girlie and honestly? iconic.

🎀 DESCRIPTION 🎀

so here's the vibe: zd_mac_tx_failed is the function that gets called when a frame couldn't be successfully transferred 💀 like, it tried, it really did, but the transfer did not slay.

when that happens, the first frame from the tx queue gets selected 👑 and it's reported as an error to the upper layers. periodt. that's the whole job — pick the first frame off the tx queue, flag it as errored, pass the bad news upward 🙈

ngl this is the "it's giving failed delivery" notification of the wireless stack 💔 somebody has to tell the upper layers, and that somebody is her.
