fm10k_update_lport_state_vf(9)

📦 version 7.3.1, in nixpkgs unstable

💖 fm10k_update_lport_state_vf(9) 💖

okay so bestie, welcome to the fm10k_update_lport_state_vf page — it lives in the Kernel API Manual and it's literally the whole vibe for telling the lower device that, hey, the state changed. buckle up 🎀

✨ SYNOPSIS ✨

s32 fm10k_update_lport_state_vf (struct fm10k_hw *hw , u16 glort , u16
count , bool enable );

that's the whole signature, no cap. it hands back an s32 and takes four things. let's go through them one by one 🫶

🌸 ARGUMENTS 🌸

  • hw — pointer to the HW structure. that's your hardware handle, your main character ✨
  • glort — unused. yep. it's there, it's cute, it does nothing 🙈
  • count — number of logical ports to enable — unused (always 1). so it's technically a count, but fr fr it's always just 1 💀
  • enable — boolean value indicating if this is an enable or disable request. so like, are we turning it on or off, bestie 👑

🦋 DESCRIPTION 🦋

Notify the lower device of a state change. that's the whole job, and it ate 💅

so if the lower device is enabled we can add filters — slay, filters incoming 🔥 and if it's disabled, all filters for this logical port are flushed. bye bye filters, we hardly knew ye 😭

heads up: the enable/disable thing isn't just a flag being set, it changes what happens to the filters — enabled means you can add them, disabled means the logical port's filters get flushed. know the difference, iykyk.

cute little sign-off: this one's from the source at ./drivers/net/ethernet/intel/f... (yes, that's literally how it's printed, truncated and all 🫠), dated October 2026, and it's the fm10k_update_lport_state_vf(9) page you just read. periodt 💜🎀
