This patch refactors the IB core umem code and vendor drivers to use a linear (chained) SG table instead of chunk list. With this change the relevant code becomes clearer—no need for nested loops to build and use umem.

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.

This patch add the support for Ethernet L2 attributes in the verbs/cm/cma structures. When dealing with L2 Ethernet, we should use smac, dmac, vlan ID and priority in a similar manner that the IB L2 (and the L4 PKEY) attributes are used. Thus, those attributes were added to the following structures: * ib_ah_attr - added dmac * ib_qp_attr - added smac and vlan_id, (sl remains vlan priority) * ib_wc - added smac, vlan_id * ib_sa_path_rec - added smac, dmac, vlan_id * cm_av - added smac and vlan_id For the path record structure, extra care was taken to avoid the new fields when packing it into wire format, so we don't break the IB CM and SA wire protocol. On the active side, the CM fills. its internal structures from the path provided by the ULP. We add there taking the ETH L2 attributes and placing them into the CM Address Handle (struct cm_av). On the passive side, the CM fills its internal structures from the WC associated with the REQ message. We add there taking the ETH L2 attributes from the WC. When the HW driver provides the required ETH L2 attributes in the WC, they set the IB_WC_WITH_SMAC and IB_WC_WITH_VLAN flags. The IB core code checks for the presence of these flags, and in their absence does address resolution from the ib_init_ah_from_wc() helper function. ib_modify_qp_is_ok is also updated to consider the link layer. Some parameters are mandatory for Ethernet link layer, while they are irrelevant for IB. Vendor drivers are modified to support the new function signature.

The micro UAR (uuar) allocator had a bug which resulted from the fact that in each UAR we only have two micro UARs avaialable, those at index 0 and 1. This patch defines iterators to aid in traversing the list of available micro UARs when allocating a uuar. In addition, change the logic in create_user_qp() so that if high class allocation fails (high class means lower latency), we revert to medium class and not to the low class.

On destroy QP the driver walks over the relevant CQ and removes CQEs reported for the destroyed QP. It also frees the related SRQ entry without checking that this is actually an SRQ-related CQE. In case of a CQ used for both send and receive QP, we could free SRQ entries for send CQEs. This patch resolves this issue by verifying that this is a SRQ related CQE by checking the SRQ number in the CQE is not zero.
