    How rdma driver converts IP address to the GID? How mlx4_en converts GID to the MAC address?




      I was trying to understand the connection establishment between two RDMA devices. There I came across the function rdma_resolve_addr() before issuing rdma_connect().

      As per the online references, rdma_resolve_addr() function resolves destination IP address to RDMA address(i.e GID). Does anyone know how this resolution is done?

      Ethernet drivers like mlx4_en then maps this GID to the MAC using GID table. How this mapping is done?
