ice_vc_set_dvm_caps(9)

💖 ice_vc_set_dvm_caps(9) 💖

ok so bestie, real talk: this is a page from the Kernel API Manual, and it's about one teeny tiny function called ice_vc_set_dvm_caps. It lives in the kernel source, it's about VLAN caps, and honestly? It's giving "small function, big responsibilities." Let's get into it 🫶

---

✨ SYNOPSIS ✨

void ice_vc_set_dvm_caps (struct ice_vf *vf , struct virtchnl_vlan_caps
*caps );

no cap, that's the whole signature. mutuals only 🤝

---

🌸 ARGUMENTS 🌸

• vf — the VF that capabilities are being set for. this is the main character of this function, lowkey 💅
• caps — the VLAN capabilities to populate. think of it as the empty little basket you're filling up 🧺✨

---

🦋 DESCRIPTION 🦋

okay so here's the vibe check: this function determines VLAN capabilities support based on whether a port VLAN is configured.

and if a port VLAN is configured? then the VF should use the inner filtering/offload capabilities — because the port VLAN is already using the outer VLAN capabilities. literally that's it. outer = taken, so inner = yours 🎀

like i said. small function. big "know your lane" energy 👑
