ixgbe_ndo_set_vf_link_state(9)

💅 ixgbe_ndo_set_vf_link_state — Set link state

okay so this is from the Kernel API Manual, bestie, and it's lowkey one of those little functions that just does exactly what it says and doesn't need a whole personality — but we're giving it one anyway 🫶

---

✨ SYNOPSIS ✨

int ixgbe_ndo_set_vf_link_state (struct net_device *netdev , int vf ,
       int state );

like, that's the whole vibe check right there. it takes three things and hands you back an int. slay 🔥

---

🎀 ARGUMENTS 🎀

• netdev — the network interface device structure, i.e. the main character of this whole operation 🌈
• vf — the VF identifier, so we know which VF we're talking about 👑
• state — the link state you want. required. no negotiating, bestie 💅

---

🦋 DESCRIPTION 🦋

so here's the tea: this function sets the link state of a specified VF, regardless of physical link state. like, it does not care what the actual physical link is doing, it is not asking permission, it is simply setting the state. main character energy fr fr ✨

ngl that "regardless of physical link state" part is the whole point — keep it in mind, iykyk 💀
