💖 irdma_find_listener(9) 💖

okay so bestie, this page comes straight out of the Kernel API Manual and it’s all about irdma_find_listener — literally “find a cm node listening on this addr-port pair.” no cap, that’s the whole vibe 🦋

🌸 NAME 🌸

irdma_find_listener — find a cm node listening on this addr-port pair 💅

✨ SYNOPSIS ✨

       struct irdma_cm_listener * irdma_find_listener (struct irdma_cm_core
       *cm_core , u32 *dst_addr , bool ipv4 , u16 dst_port , u16 vlan_id , enum
       irdma_cm_listener_state listener_state );

🎀 ARGUMENTS 🎀

okay here’s the friend group you pass in, and yes every single one matters:

• cm_core — cm’s core. that’s the main character right there 👑
• dst_addr — listener ip addr. the address bestie is listening on 🫶
• ipv4 — flag indicating IPv4 when true. so when it’s true, we’re on that IPv4 vibe ✅
• dst_port — listener tcp port num. the port number, periodt 🔥
• vlan_id — virtual LAN ID. vlan energy 🌈
• listener_state — state to match with listen node’s. you’re matching against the listen node’s state 🎯
