ice_vc_is_valid_vlan(9)

💖 ice_vc_is_valid_vlan (9) 💖

okay bestie, so this little icon is straight out of the Kernel API Manual — section 9, no cap — and she has exactly one job: telling you whether a VLAN thing is valid or not. let's get into it 🫶

---

✨ NAME ✨

ice_vc_is_valid_vlan — validate the virtchnl_vlan

like literally, that's the whole personality. she validates. that's it. 💅

---

🌸 SYNOPSIS 🌸

bool ice_vc_is_valid_vlan (struct virtchnl_vlan *vc_vlan );

so she takes one pointer and gives you back a bool. true or false, yes or no, slay or not-slay. ⭐

---

🎀 ARGUMENTS 🎀

• vc_vlan — the virtchnl_vlan you want validated. that's the one. the main character. give it a vibe check 🔥

---

🦋 DESCRIPTION 🦋

here's the tea, and ngl it's simple:

if the VLAN TCI and the VLAN TPID are both 0, then this filter is invalid — so she returns false. 💀

otherwise she returns true. periodt. ✨

that's the whole function. no hidden lore, no extra options, just a little zero-check doing its job beautifully. no cap, i'm obsessed. 👑
