This patch implements IB_WR_REG_SIG_MR posted by the user. Baisically this WR involves 3 WQEs in order to prepare and properly register the signature layout: 1. post UMR WR to register the sig_mr in one of two possible ways: * In case the user registered a single MR for data so the UMR data segment consists of: - single klm (data MR) passed by the user - BSF with signature attributes requested by the user. * In case the user registered 2 MRs, one for data and one for protection, the UMR consists of: - strided block format which includes data and protection MRs and their repetitive block format. - BSF with signature attributes requested by the user. 2. post SET_PSV in order to set the memory domain initial signature parameters passed by the user. SET_PSV is not signaled and solicited CQE. 3. post SET_PSV in order to set the wire domain initial signature parameters passed by the user. SET_PSV is not signaled and solicited CQE. * After this compound WR we place a small fence for next WR to come. This patch also introduces some helper functions to set the BSF correctly and determining the signature format selectors.

If user requested signature enable we initialize relevant mlx5_ib_qp members. We mark the qp as sig_enable and we increase the effective SQ size, but still limit the user max_send_wr to original size computed. We also allow the create_qp routine to accept sig_enable create flag. Signed-off-by: NSagi Grimberg <sagig@mellanox.com> Signed-off-by: NRoland Dreier <roland@purestorage.com>

The driver is comprised of two kernel modules: mlx5_ib and mlx5_core. This partitioning resembles what we have for mlx4, except that mlx5_ib is the pci device driver and not mlx5_core. mlx5_core is essentially a library that provides general functionality that is intended to be used by other Mellanox devices that will be introduced in the future. mlx5_ib has a similar role as any hardware device under drivers/infiniband/hw.
