irdma_access_mcast_grp(9)

💖 NAME 💖

okay bestie, welcome to irdma_access_mcast_grp(9) from the Kernel API Manual — this one is literally “Access mcast group based on op.” That's the whole vibe: you're accessing an mcast group, and op is what tells you which operation to do. No cap.

🦋 SYNOPSIS 🦋

int irdma_access_mcast_grp (struct irdma_sc_cqp *cqp , struct
       irdma_mcast_grp_info *info , u32 op , u64 scratch );

✨ ARGUMENTS ✨

• cqp — the Control QP. She's the control queen here.
• info — multicast group context info, aka the context cutie.
• op — the operation to perform. This is the “which access are we doing?” moment.
• scratch — a u64 saved to be used during cqp completion. Keep it around for the completion era, iykyk.
