i40e_nvmupd_...date_command(9)

📦 version 7.3.1, in nixpkgs unstable

💅 i40e_nvmupd_validate_command — NAME

okay so bestie, welcome to the Kernel API Manual (section 9, we're fancy like that ✨). This page is all about i40e_nvmupd_validate_command — and its official whole vibe is "Validate given command" 🎀. That's it, that's the job. She validates. She does not execute, she does not write, she just looks at your command and goes "hmm, valid or nah" 💅.

✨ SYNOPSIS ✨

enum i40e_nvmupd_cmd i40e_nvmupd_validate_command (struct i40e_hw *hw ,
struct i40e_nvm_access *cmd , int *perrno );

look at her go 🫶 three args in, one enum out, and she's got opinions about all of them.

🦋 ARGUMENTS 🦋

  • hw — pointer to hardware structure. yes girl, the actual hardware 💖 this is where the NIC lives.
  • cmd — pointer to nvm update command buffer. this is the command you're asking her to judge 🌸 she will look at it very seriously.
  • perrno — pointer to return error code. if something's off, this is where the tea gets spilled 😭 it's a pointer so she can write back to you, not just gossip behind your back.

👑 DESCRIPTION 👑

so what does she actually do? Return one of the valid command types or I40E_NVMUPD_INVALID 🔥 That's the whole bit. You hand her a command, she checks it, and you get back either a legit command type (slay ✨) or I40E_NVMUPD_INVALID (oop 💀) — no in-between, no half-valid situationship, no cap.

literally that's it, she's not doing the update for you, she's the vibe check at the door 🚪💅
