2017-10-18i40iw: Move cqp_cmd_head init to CQP initializationBob Sharp
Control QP (CQP) command backlog list is initialized at device initialization time. It is not reinitialized in the reset flow. Move the initialization to CQP creation time so the list can be initialized correctly for reset as well.

2017-10-18i40iw: Remove UDA QP from QoS list if creation failsIvan Barrera
If User-space Direct Access (UDA) QP creation fails, the QP entry is not removed from QoS list. Fix this by removing QP from QoS list if create QP fails.

2017-10-18i40iw: Clear CQP Head/Tail during initializationChristopher Bednarz
Clear Control Queue Pair (CQP) Head/Tail on CQP initialization as during an adapter reset, these values are not reinitialized. Tail is cleared by writing 0 to CQP's tail register. Head is cleared by writing 0 to CQP's doorbell register.

2017-10-18i40iw: Reinitialize IEQ on MTU changeShiraz Saleem
On a netdev MTU change event, the iWARP Exception Queue (IEQ) buffers may not be sized properly to handle the new MTU. Reinitialize the IEQ with new MTU size on MTU change event. Also, add define for the max ethernet frame size field in IEQ QP context instead of the snd_mss define which is for iWARP QPs' MSS field.

2017-09-22i40iw: Add support for port reuse on active side connectionsShiraz Saleem
During OpenMPI scale up testing, we observe rdma_connect failures if ports are reused on multiple connections.

2017-09-22i40iw: Prevent multiple netdev event notifier registrationsShiraz Saleem
Netdev event notifier registration/de-registration is not synchronized with a lock and there is a possibility of a duplicate registration of notifier before the unregister completes. Register netdev event notifiers during module init and de-register them at module exit. This avoids the need to tie the registration to first netdev client interface open and de-registration to last client interface close and the synchronization to achieve it. This also fixes a crash due to duplicate registration.

The current timeout logic for Control Queue-Pair (CQP) OPs does not take into account whether CQP makes progress but rather blindly waits for a large timeout value, 100000 jiffies for the completion event. Improve this by setting the timeout based on whether the CQP is making progress or not. If the CQP is hung, the timeout will happen sooner, in 5000 jiffies. Each time the CQP progress is detetcted, the timeout extends by 5000 jiffies.

2017-08-10RDMA: Simplify get firmware interfaceLeon Romanovsky
There is a need to forward FW version to user space application through RDMA netlink. In order to make it safe, there is need to declare nla_policy and limit the size of FW string. The new define IB_FW_VERSION_NAME_MAX will limit the size of FW version string. That define was chosen to be equal to ETHTOOL_FWVERS_LEN, because many drivers anyway are limited by that value indirectly. The introduction of this define allows us to remove the string size from get_fw_str function signature. Signed-off-by: Leon Romanovsky <leonro@mellanox.com>
2017-07-24RDMA: Remove useless MODULE_VERSIONLeon Romanovsky
All modules in drivers/infiniband defined and used MODULE_VERSION, which was pointless because the kernel version describes their state more accurate then those arbitrary numbers.

2017-07-20IB/i40iw: Fix error code in i40iw_create_cq()Dan Carpenter
We accidentally forgot to set the error code if ib_copy_from_udata() fails. It means we return ERR_PTR(0) which is NULL and results in a NULL dereference in the callers.

2017-07-20i40iw: Free QP PBLEs when the QP is destroyedTatyana Nikolova
If the physical buffer list entries (PBLEs) of a QP are freed up at i40iw_dereg_mr, they can be assigned to a newly created QP before the previous QP is destroyed. Fix this by freeing PBLEs only when the QP is destroyed.

Control Queue Pair (CQP) request objects, which have not received a completion upon interface close, remain in memory. To fix this, identify and free all pending CQP request objects during destroy CQP OP.
