xgmac_poll(9)

📦 version 7.3.1, in nixpkgs unstable

💅 xgmac_poll — the Kernel API Manual, but make it group chat

ok so bestie, we're looking at xgmac_poll from the Kernel API Manual, and honestly? she's kind of a big deal. she's the xgmac poll method, and yes — that's NAPI, no cap. 🔥

🌸 SYNOPSIS 🌸

int xgmac_poll (struct napi_struct *napi , int budget );

literally the whole vibe in one line. int in, int out, two args, iconic. ✨

🎀 ARGUMENTS 🎀

  • napi — pointer to the napi structure. that's it, that's the whole description. she points at the napi struct and we move on. 🫶
  • budget — the maximum number of packets that the current CPU can receive from all interfaces. so like, it's a limit on how much the current CPU is allowed to scoop up from all the interfaces combined. know your limits, queen. 💅

🦋 DESCRIPTION 🦋

okay so what does she actually do? two things:

  1. this function implements the reception process. yes, reception, as in receiving — she's handling the receiving side of things. 💖
  2. also it runs the TX completion thread. so she's multitasking. reception and TX completion, in one function. main character energy fr fr. 👑

🌈 SEE ALSO 🌈

the kernel file you should lowkey go read:

./drivers/net/ethernet/calxeda/xgmac.c

and the whole friend group, in order, exactly as listed:

iykyk — go read them, they're all in their xgmac era together. 💜

ngl bestie, that's genuinely the whole page. she's short, she's sweet, she implements the reception process and runs the TX completion thread, and she lives in ./drivers/net/ethernet/calxeda. periodt. 🍓

and that's a wrap on xgmac_poll(9) from the Kernel API Manual, straight outta ./drivers/net/ethernet/calxeda, dated October 2026 — mwah, love u, go check your budget before you receive anything 💋🧚‍♀️
