🌸 SYNOPSIS 🌸

the signature is literally giving:

       void irdma_build_mpa_v1 (struct irdma_cm_node *cm_node , void
       *start_addr , u8 mpa_key );

πŸ’… ARGUMENTS πŸ’…

  • cm_node β€” connection's node, aka the connection bestie this whole thing belongs to. 🫢
  • start_addr β€” address where to build frame. yes, literally the spot where the frame gets built. ✨
