irdma_if_notify(9)

💅 irdma_if_notify ✨

okay so welcome to the Kernel API Manual page for irdma_if_notify(9) — yes that's the manual name, yes we're saying it up top like a name drop, because this function is lowkey the one handling your interface going bye bye 🫶

---

🌸 NAME 🌸

irdma_if_notify — process an ifdown on an interface 💀

like, when your interface goes down? this is the girl that deals with it. no cap.

---

✨ SYNOPSIS ✨

void irdma_if_notify (struct irdma_device *iwdev , struct net_device
     *netdev , u32 *ipaddr , bool ipv4 , bool ifup );

she takes five things and returns literally nothing (void). main character energy tbh 👑

---

🎀 ARGUMENTS 🎀

• iwdev — device pointer. it's your struct irdma_device *, the whole vibe of the device, the source of truth fr fr 🦋
• netdev — network device structure. the struct net_device * in question, i.e. the actual interface we're talking about 🥺
• ipaddr — Pointer to IPv4 or IPv6 address. pointer!! u32 *, so watch where you're pointing bestie 🙈
• ipv4 — flag indicating IPv4 when true. bool. true = it's giving IPv4 🌈
• ifup — flag indicating interface up when true. bool. true = interface is up, and we all love an up interface 💖

ngl the flags are booleans, so it's true/false only, no in-between, no situationships 💅
