This commit takes care of the generated signature error CQE generated by the HW (if happened). The underlying mlx5 driver will handle signature error completions and will mark the relevant memory region as dirty. Once the consumer gets the completion for the transaction, it must check for signature errors on signature memory region using a new lightweight verb ib_check_mr_status(). In case the user doesn't check for signature error (i.e. doesn't call ib_check_mr_status() with status check IB_MR_CHECK_SIG_STATUS), the memory region cannot be used for another signature operation (REG_SIG_MR work request will fail).

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.

Support create_mr and destroy_mr verbs. Creating ib_mr may be done for either ib_mr that will register regular page lists like alloc_fast_reg_mr routine, or indirect ib_mrs that can register other (pre-registered) ib_mrs in an indirect manner. In addition user may request signature enable, that will mean that the created ib_mr may be attached with signature attributes (BSF, PSVs). Currently we only allow direct/indirect registration modes.

When scanning netdevices we need to check a few more conditions and cases to build the IBoE GID table properly. For example, under bonding we must make sure that when a port is down, the bond IP address isn't programmed as a GID, since doing so will cause failure with IB core flows that selects ports by GID.

The IBoE code used to reset the GID table did it for all Ethernet ports of the device. Since the whole architecture of generating GIDs and responding to events is port-based, this is inefficient and can lead to wrong content in the GID table. Change the reset flow to be per-port.

Updating the GID table under IBoE requires read/write from/to shared data structures. These data structures are protected with the device iboe lock. The flows that modify the GID table start from 1. Initializing the GID table 2. NETDEV events 3. INET or INET6 events This patch makes sure that the flow of initializing the GID table is consistent with the other two flows w.r.t on what step the lock is taken.

On the one hand, the invocation of netdev_master_upper_dev_get() within mlx4_ib_scan_netdevs() must be done with rtnl lock held. On the other hand, it's wrong to call rtnl_lock() from within this function since it's also called by our netdev notifier callback. Therefore move the locking to mlx4_ib_add() so that both cases are covered.

Make sure that for Ethernet ports, the port GID table index 0 is always occupied with a default GID of the relevant IPv6 link-local adderss. This provides better user experience for legacy applications that don't use the RDMA CM and were working on index 0 prior to the IP addressing change. Also, as GIDs are generated from IP addresses of the network devices that are associated with the port, it's basically possible that the GID table will be empty if no IP address was assigned. This doesn't comply with the IB spec section 4.1.1 "GID usage and properties".

Commit c1be5232 ("Fix micro UAR allocator") broke binary compatibility between libmlx5 and mlx5_ib since it defines a different value to the number of micro UARs per page, leading to wrong calculation in libmlx5. This patch defines struct mlx5_ib_alloc_ucontext_req_v2 as an extension to struct mlx5_ib_alloc_ucontext_req. The extended size is determined in mlx5_ib_alloc_ucontext() and in case of old library we use uuarn 0 which works fine -- this is acheived due to create_user_qp() falling back from high to medium then to low class where low class will return 0. For new libraries we use the more sophisticated allocation algorithm.
