wx_set_vlvf(9)

💅 wx_set_vlvf — the kernel API manual, bestie edition ✨

okay so real talk, this page is wx_set_vlvf from the kernel API manual (section 9, kernel-land, no userland shenanigans here 🫶). It's the lowkey hero that flips a lil bit in the VLVF table, and I'm gonna walk you through it like we're texting at 2am. 🦋

✨ NAME ✨

wx_set_vlvf — Set VLAN Pool Filter. that's it, that's the vibe. 💅

---

🌸 SYNOPSIS 🌸

int wx_set_vlvf (struct wx *wx , u32 vlan , u32 vind , bool vlan_on ,
bool *vfta_changed );

like, yes, it does return an int. yes, the params are a little stacked. no, we're not scared of it. 😌

🎀 ARGUMENTS 🎀

• wx — pointer to hardware structure. it's the whole hardware situation, the main character of this function ngl 👑
• vlan — the VLAN id you're writing to the VLAN filter. u32, obviously 💖
• vind — the VMDq output index that maps a queue to a VLAN id in VFVFB. iykyk 🧚
• vlan_on — a bool flag: turn VLAN on in VFVF, or off. flip the switch bestie ⭐
• vfta_changed — pointer to a bool flag that tells you whether VFTA should be changed. ngl it's the gossip flag, it reports back 🙈

---

💜 DESCRIPTION 💜

Turn on/off the specified bit in the VLVF table. literally that's the whole job and she does it slayfully. ✨
