[rds-devel] [PATCH]: Add depend check of infinibind

[Joe Jin]

Hi, 

My kernel dont configured INFINIBIND, and when I compiled and insert the module,
follow errors reported:

rds: Unknown symbol ib_create_cq
rds: Unknown symbol rdma_resolve_addr
rds: Unknown symbol rdma_disconnect
rds: Unknown symbol rdma_resolve_route
rds: Unknown symbol rdma_bind_addr
rds: Unknown symbol rdma_create_qp
rds: Unknown symbol ib_destroy_cq
rds: Unknown symbol rdma_create_id
rds: Unknown symbol rdma_listen
rds: Unknown symbol rdma_destroy_qp
rds: Unknown symbol ib_get_dma_mr
rds: Unknown symbol ib_alloc_pd
rds: Unknown symbol rdma_connect
rds: Unknown symbol rdma_destroy_id
rds: Unknown symbol rdma_accept
rds: Unknown symbol ib_dealloc_pd

from the source I known it must have INFINIBIND support. 
however, the configure and Kconfig(for kernel patch?) never check it.

next patch should use for this check, pls apply it.

Regards.
Joe.Jin
