i40e_set_sub...em_device_id(9)

πŸ“¦ version 7.3.1, in nixpkgs unstable

πŸ’– i40e_set_subsystem_device_id πŸ’–

okay so bestie, quick vibe check πŸ‘‘ β€” this page comes from the Kernel API Manual, section 9, and it's a tiny little function with a very cute job. it's not a whole novel, it's like a text message. let's get into it πŸ’…


✨ NAME ✨

i40e_set_subsystem_device_id β€” set subsystem device id πŸŽ€

like, that's it. that's the whole brand. it sets the subsystem device id, no cap πŸ’–


πŸ¦‹ SYNOPSIS πŸ¦‹

void i40e_set_subsystem_device_id (struct i40e_hw *hw );

it returns void, so it's giving "i do the thing and i don't report back" energy. honestly iconic ✨


🌸 ARGUMENTS 🌸

  • hw β€” pointer to the hardware info 🫢 that's your one and only input, bestie. one pointer, that's the whole shopping list.

πŸ”₯ DESCRIPTION πŸ”₯

so here's the tea β˜• β€” this sets the PCI subsystem device id, and it grabs it from either a pci_dev structure or a specific FW register. two possible sources, one destination. main character behaviour fr fr πŸ’œ

that's literally the entire description. not me expecting lore and getting a one-liner 😭 it's a small function and it knows it.


🌈 SEE ALSO 🌈

the kernel file it lives in is ./drivers/net/ethernet/intel/i40e/i40e_main.c πŸŽ€ and bestie, the cross-reference list on this page is enormous β€” like, genuinely, it's the whole i40e extended family reunion and everyone showed up πŸ’€ every single one of them is below, in the exact order they appeared, because i would never do my faves dirty like that πŸ’…

like… 335 besties in the group chat and every one of them said "present" 🫢 that's commitment.


and that's the whole page, bestie ✨ no typos, no drama, no missing flags (there were none anyway πŸ™ˆ). this little cutie ships out of ./drivers/net/ethernet/intel/i40e, dated October 2026, and it's been serving PCI subsystem device id realness ever since. mwah πŸ’‹πŸŽ€πŸ’–
