IB/srp: Use FMRs to map gather/scatter lists
Create an SRP FMR pool on HCAs that support FMRs, and use FMRs to map gather/scatter lists that have more than one entry into a single memory region that appears virtually contiguous to the SRP target (which is the RDMA initiator). This patch bails out on FMR mapping for SCSI commands where the gather/scatter list cannot be mapped into a single FMR because there are sub-page-sized entries in middle of the list. An unaligned start or end of the list is OK. Based on a patch by Vu Pham <vuhuong@mellanox.com>. Signed-off-by: Roland Dreier <rolandd@cisco.com>
