The following patch series extends the rdma_cm to support native
Infiniband addressing through the use of a new AF_IB address family
and RDMA_PS_IB port space.
It defines a new struct sockaddr_ib that may be used to specify an
IB GID, along with other IB address attributes, such as the pkey and
service ID.
The higher level intent is to support a user space call, rdma_getaddrinfo,
which can return AF_IB addresses to an application. This allows the
rdma_cm to support transport specific features, such as failover and
non-reversible paths, and eliminates the need for the kernel to perform
address and route resolution. (An implementation of rdma_getaddrinfo is
included in a separate patch set to the librdmacm.)
