ixgbe_host_i...face_command(9)

📦 version 7.3.1, in nixpkgs unstable

💖 NAME 💖

Okay so bestie, this is ixgbe_host_interface_command(9) from the Kernel API Manual — the page for ixgbe_host_interface_command, aka the function that issues a command to the manageability block. It’s giving “talk to the firmware side” energy, and we’re gonna read it together. 💅

✨ SYNOPSIS ✨

int ixgbe_host_interface_command (struct ixgbe_hw *hw , void *buffer ,
       u32 length , u32 timeout , bool return_data );

🎀 ARGUMENTS 🎀

  • hw — pointer to the HW structure. It’s the hardware bestie. 🫶
  • buffer — contains the command to write, and it’s also where the return status will be placed. Literally both directions, slay.
  • length — length of buffer; it must be a multiple of 4 bytes. Not 3, not 5 — 4-byte girlies only. 🎀
  • timeout — time in ms to wait for command completion. Tick tock ⏳.
  • return_data — read and return data from the buffer (true) or not (false). Needed because FW structures are big endian and decoding of these fields can be 8 bit or 16 bit based on command. Decoding is not easily understood without making a table of commands. So we will leave this up to the caller to read back the data in these cases.

🦋 DESCRIPTION 🦋

This function communicates with the manageability block. On success it returns 0; otherwise it returns -EIO or -EINVAL. That’s the vibe check: 0 = slay, negative errno = not slay. 😭

Cute sign-off time 🎀: source/version is ./drivers/net/ethernet/intel/i..., date is October 2026, and the page tag is ixgbe_host_i...face_command(9). Bye bestie, go talk to that manageability block responsibly 💅✨
