rdma_resolve_addr - Resolve destination and optional source addresses.
int rdma_resolve_addr (struct rdma_cm_id *id, struct sockaddr
*src_addr, struct sockaddr *dst_addr, int timeout_ms);
id RDMA identifier.
src_addr Source address information. This parameter may be NULL.
dst_addr Destination address information.
timeout_ms Time to wait for resolution to complete.
Resolve destination and optional source addresses from IP addresses to
an RDMA address. If successful, the specified rdma_cm_id will be bound
to a local device.
This call is used to map a given destination IP address to a usable
RDMA address. The IP to RDMA address mapping is done using the local
routing tables, or via ARP. If a source address is given, the
rdma_cm_id is bound to that address, the same as if rdma_bind_addr were
called. If no source address is given, and the rdma_cm_id has not yet
been bound to a device, then the rdma_cm_id will be bound to a source
address based on the local routing tables. After this call, the
rdma_cm_id will be bound to an RDMA device. This call is typically
made from the active side of a connection before calling
rdma_resolve_route and rdma_connect.
This call maps the destination and, if given, source IP addresses to
GIDs. In order to perform the mapping, IPoIB must be running on both
the local and remote nodes.
