NAME

       rdma_resolve_addr - Resolve destination and optional source addresses.

SYNOPSIS

       #include <rdma/rdma_cma.h>

       int   rdma_resolve_addr   (struct   rdma_cm_id   *id,  struct  sockaddr
       *src_addr, struct sockaddr *dst_addr, int timeout_ms);

ARGUMENTS

       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.

DESCRIPTION

       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.

RETURN VALUE

       Returns 0 on success, or -1 on error.  If an error occurs,  errno  will
       be set to indicate the failure reason.

NOTES

       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.

INFINIBAND SPECIFIC

       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.
