💖 fm10k_iov_set_lport_pf(9) — the glamourous little kernel manual 💖

okay so bestie, welcome to the fm10k_iov_set_lport_pf(9) page from the Kernel API Manual ✨ this is the one where we hand a virtual function its very own logical port and turn the lights on. she's a kernel function, she's a PF-side queen, and she's lowkey the reason your VF can actually receive packets. let's get into it 🎀

🌸 NAME 🌸

fm10k_iov_set_lport_pf — assign and enable a logical port for a given VF 💅

✨ SYNOPSIS ✨

s32 fm10k_iov_set_lport_pf (struct fm10k_hw *hw , struct fm10k_vf_info
*vf_info , u16 lport_idx , u8 flags );

she takes four args and returns an s32, that's the whole vibe 🫶

🦋 ARGUMENTS 🦋

  • hw — pointer to hardware structure. this is the hardware struct, the main character of the whole operation ngl
  • vf_info — pointer to VF information structure. this is where the VF's info lives, and yes it's about to get updated 💖
  • lport_idx — logical port offset from the hardware glort. it's a u16, it's the offset, and it's giving coordinates 🗺️
  • flags — set of capability flags to extend port beyond basic functionality. a u8 full of potential, we love a flexible icon ✨

💜 DESCRIPTION 💜

so what does she actually do? this function allows enabling a VF port by assigning it a GLORT and setting the flags so that it can enable an Rx mode. that's it, that's the whole slay 💅

like, literally: give the port a GLORT, set the flags, and now it can turn on an Rx mode. no cap, that's the entire job and she does it well 👑

k bye ily, this page came from ./drivers/net/ethernet/intel/f... and it's dated October 2026, and the manual name is fm10k_iov_set_lport_pf(9) in case you forgot already 🙈 go assign those ports, you gorgeous kernel dev 🌸🦋💖
