irdma_alloc_set_mac(9)

📦 version 7.3.1, in nixpkgs unstable

💅 irdma_alloc_set_mac 💅

okay so this is a page from the Kernel API Manual (section 9, bestie — kernel-level stuff, iykyk) and it's all about one tiny little function that does one tiny little thing. but like, an important thing. let's get into it 🫶

✨ NAME ✨

irdma_alloc_set_mac — set up a mac address table entry 🌸

like, it allocates and sets up an entry in the mac address table. that's the whole vibe.

🦋 SYNOPSIS 🦋

int irdma_alloc_set_mac (struct irdma_device *iwdev );

she takes exactly one argument and returns an int. no cap, that's it. 💅

🎀 ARGUMENTS 🎀

  • iwdev — the irdma device 💖 (like, the actual device you're doing this for. main character energy.)

🔥 DESCRIPTION 🔥

so what she does is: allocate a mac ip entry and add it to the hw table. that's the whole job bestie, and she does it. ✨

and then — the return situation — she returns 0 if it's successful, otherwise she returns error 😭. so like, 0 is the slay outcome, anything else is giving "something went wrong". check your return values, periodt.

👑 SEE ALSO 👑

the kernel file lives right here, in case you wanna go read the source yourself (respect):

./drivers/infiniband/hw/irdma/hw.c

and here's the whole friend group — every single one of these functions is linked up:

like I said. the whole group chat. 🫶✨

ngl bestie, this page is short but she's doing her job — allocate, add to the hw table, return 0 on success or an error otherwise. iconic behaviour, no notes. 💜

okay and the little sign-off corner: this came out of the ./drivers/infiniband/hw/irdma directory, dated October 2026, and it's the irdma_alloc_set_mac(9) page in the kernel manual set. slay, go read the source, bye bestie 💖🎀🦋
