ice_check_if_dflt_vsi(9)

💅 ice_check_if_dflt_vsi — from the Kernel API Manual, section (9) 🧚

okay so bestie, we're in the kernel API manual today and honestly? this one is short and sweet and we're gonna slay it. ice_check_if_dflt_vsi is the function, it lives in section (9) of the Kernel API Manual, and its whole entire job is literally in the name. let's get into it 💖

---

✨ NAME ✨

ice_check_if_dflt_vsi — check if VSI is default VSI 🎀

like... that's it. that's the function. vibe check for VSIs, no cap.

---

🦋 SYNOPSIS 🦋

bool ice_check_if_dflt_vsi (struct ice_port_info *pi , u16 vsi_handle ,
       bool *rule_exists );

she returns a bool, periodt. three args, all in the block above, copy them exactly bestie 🙈

---

🌸 ARGUMENTS 🌸

• pi — pointer to the port_info structure, your main character struct fr fr
• vsi_handle — the vsi handle to check for in the filter list, iykyk
• rule_exists — indicates if there are any VSI's in the rule list (yes it's an out-param, she's reporting back to you 💌)

---

💜 DESCRIPTION 💜

so what does she actually do? she checks if the VSI is in a default VSI list, and — bonus — also indicates if the default VSI list is empty. that's the whole thing. short queen, iconic behavior, ate and left no crumbs 👑

and that's the whole page!! 🫶 she's from ./drivers/net/ethernet/intel/ice, version October 2026, and the manual page title is ice_check_if_dflt_vsi(9) — so like, if you ever forget where this came from, it's right there ✨ mwah, go read some kernel source, ily, bye 🍓💖
