разрешить адреса назначения и необязательные исходные адреса (Resolve destination and optional source addresses.)
Имя (Name)
rdma_resolve_addr - Resolve destination and optional source
addresses.
Синопсис (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);
Аргументы (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.
Описание (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.
Возвращаемое значение (Return value)
Returns 0 on success, or -1 on error. If an error occurs, errno
will be set to indicate the failure reason.
Примечание (Note)
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.
Cпецифический InfiniBand (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.
