Bart Van Assche d6c58dc40f IB/SRP: Avoid using IB_MR_TYPE_SG_GAPS ... Tests have shown that the following error message is reported when using SG-GAPS registration with an mlx5 adapter: scsi host1: ib_srp: failed RECV status WR flushed (5) for CQE ffff880bd4270eb0 00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000000 0f007806 2500002a ad9fafd1 scsi host1: ib_srp: reconnect succeeded mlx5_0:dump_cqe:262:(pid 7369): dump error cqe 00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000000 0f007806 25000032 00105dd0 scsi host1: ib_srp: failed FAST REG status memory management operation error (6) for CQE ffff880b92860138 Hence avoid using SG-GAPS memory registrations. Additionally, always configure the blk_queue_virt_boundary() to avoid to trigger a mapping failure when using adapters that support SG-GAPS (e.g. mlx5).
