This patch exposes the option to dynamic allocates a UAR, this functionality will be used in downstream patch in this series as part of QP creation. Specifically, the user space driver asks for a UAR allocation in a given page index, upon success this UAR and its bfregs can be used as part of QP creation by the user space driver. To enable allocating more than 256 UARs the page index is encoded in an extra one byte just after the command byte.

This patch extends the alloc context flow to be prepared for working with dynamic UAR allocations. Currently upon alloc context there is some fix size of UARs that are allocated (named 'static allocation') and there is no option to user application to ask for more or control which UAR will be used by which QP. In this patch the driver prepares its data structures to manage both the static and the dynamic allocations and let the user driver knows about the max value of dynamic blue-flame registers that are allowed. Downstream patches from this series will enable the dynamic allocation and the association as part of QP creation.

ibmr.device is being set only after ib_alloc_mr() is (successfully) complete. Therefore, in case mlx5_core_create_mkey() return with error, the error flow calls mlx5_free_priv_descs() which uses ibmr.device (which doesn't exist yet), causing a NULL dereference oops. To fix this, the IB device should be set in the mr struct earlier stage (e.g. prior to calling mlx5_core_create_mkey()).

The LLP_DOUBT_REACHABILITY Asynchronous Event (AE) is an early warning of a connection issue. It is followed by LLP_TOO_MANY_RETRIES AE, if the retransmit threshold is reached and recovery is not possible for the connection. Currently we terminate the connection on receiving the LLP_DOUBT_REACHABILITY AE. Ignore this AE and terminate the connection only on LLP_TOO_MANY_RETRIES AE. This improves the user experience on cable disconnect/reconnect scenario while running iWARP traffic. On cable disconnect, the QP traffic is paused and the user has a larger and more reasonable timeout within which if the cable is reconnected, traffic can continue.
