In older FW versions the completion flag was treated as the ack flag in edpm messages. commit ff937b91 ("qed: Add EDPM mode type for user-fw compatibility") exposed the FW option of setting which mode the QP is in by adding a flag to the qedr <-> qed API. This patch adds the qedr <-> libqedr interface so that the libqedr can set the flag appropriately and qedr can pass it down to FW. Flag is added for backward compatibility with libqedr. For older libs, this flag didn't exist and therefore set to zero. Fixes: ac1b36e5 ("qedr: Add support for user context verbs") Link: https://lore.kernel.org/r/20200707063100.3811-2-michal.kalderon@marvell.comSigned-off-by:

QP's with the same SRQ, working on different CQs and running in parallel on different CPUs could lead to a race when maintaining the SRQ consumer count, and leads to FW running out of SRQs. Update the consumer atomically. Make sure the wqe_prod is updated after the sge_prod due to FW requirements.

Current iSER target code allocates MR pool budget based on queue size. Since there is no handshake between iSER initiator and target on max IO size, we'll set the iSER target to support upto 16MiB IO operations and allocate the correct number of RDMA ctxs according to the factor of MR's per IO operation. This would guarantee sufficient size of the MR pool for the required IO queue depth and IO size. Link: https://lore.kernel.org/r/20200708091908.162263-1-maxg@mellanox.comReported-by:

With the "PID" category QPs have same PID will be bound to same counter; If this category is not set then QPs have different PIDs will be bound to same counter. This is implemented for 2 reasons: 1. The counter is a limited resource, while there may be dozens of applications, each of which creates several types of QPs, which means it may doesn't have enough counter. 2. The system administrator needs all QPs created by all applications with same type bound to one counter. The counter name and PID is only make sense when "PID" category are configured. This category can also be used in combine with others, e.g. QP type. Link: https://lore.kernel.org/r/20200702082933.424537-2-leon@kernel.orgSigned-off-by:

There are number of counters types supported in mlx5_ib: HW counters, congestion counters, Q-counters and flow counters. Almost all supporting code was placed in main.c that made almost impossible to maintain the code anymore. Let's create separate code namespace for the counters to easy future generalization effort.

Michael Guralnik says: ==================== This series handles IPoIB child interface creation with setting interface's HW address. In current implementation, lladdr requested by user is ignored and overwritten. Child interface gets the same GID as the parent interface and a QP number which is assigned by the underlying drivers. In this series we fix this behavior so that user's requested address is assigned to the newly created interface. As specific QP number request is not supported for all vendors, QP number requested by user will still be overwritten when this is not supported. Behavior of creation of child interfaces through the sysfs mechanism or without specifying a requested address, stays the same. ==================== Based on the mlx5-next branch at git://git.kernel.org/pub/scm/linux/kernel/git/mellanox/linux due to dependencies. * branch 'mlx5_ipoib_qpn': RDMA/ipoib: Handle user-supplied address when creating child net/mlx5: Enable QP number request when creating IPoIB underlay QP Signed-off-by: -
