net/mlx5: Increase number of max QPs in default profile

2017-04-07T07:17:56Z

[ Upstream commit 5f40b4ed975c26016cf41953b7510fe90718e21c ] With ConnectX-4 sharing SRQs from the same space as QPs, we hit a limit preventing some applications to allocate needed QPs amount. Double the size to 256K.

IB/mlx4: Fix port query for 56Gb Ethernet links

2017-01-26T16:40:57Z

commit 6fa26208206c406fa529cd73f7ae6bf4181e270b upstream. Report the correct speed in the port attributes when using a 56Gbps ethernet link. Without this change the field is incorrectly set to 10.

IB/mlx4: Set traffic class in AH

2017-01-26T16:40:57Z

commit af4295c117b82a521b05d0daf39ce879d26e6cb1 upstream. Set traffic class within sl_tclass_flowlabel when create iboe AH. Without this the TOS value will be empty when running VLAN tagged traffic, because the TOS value is taken from the traffic class in the address handle attributes.

IB/mlx5: Fix fatal error dispatching

2016-11-24T15:23:58Z

commit dbaaff2a2caa03d472b5cc53a3fbfd415c97dc26 upstream. When an internal error condition is detected, make sure to set the device inactive after dispatching the event so ULPs can get a notification of this event.

IB/mlx5: Use cache line size to select CQE stride

2016-11-24T15:23:58Z

commit 16b0e0695a73b68d8ca40288c8f9614ef208917b upstream. When creating kernel CQs use 128B CQE stride if the cache line size is 128B, 64B otherwise. This prevents multiple CQEs from residing in a 128B cache line, which can cause retries when there are concurrent read and writes in one cache line. Tested with IPoIB on PPC64, saw ~5% throughput improvement.

commit 593ff73bcfdc79f79a8a0df55504f75ad3e5d1a9 upstream. Currently, if ib_copy_to_udata fails, the CQ won't be deleted from the radix tree and the HW (HW2SW).

IB/mlx4: Fix incorrect MC join state bit-masking on SR-IOV

2016-10-07T08:06:57Z

commit e5ac40cd66c2f3cd11bc5edc658f012661b16347 upstream. Because of an incorrect bit-masking done on the join state bits, when handling a join request we failed to detect a difference between the group join state and the request join state when joining as send only full member (0x8). This caused the MC join request not to be sent. This issue is relevant only when SRIOV is enabled and SM supports send only full member. This fix separates scope bits and join states bits a nibble each.

IB/mlx4: Fix the SQ size of an RC QP

2016-08-19T07:51:23Z

commit f2940e2c76bb554a7fbdd28ca5b90904117a9e96 upstream. When calculating the required size of an RC QP send queue, leave enough space for masked atomic operations, which require more space than "regular" atomic operation.

IB/mlx5: Fix post send fence logic

2016-08-19T07:51:22Z

commit c9b254955b9f8814966f5dabd34c39d0e0a2b437 upstream. If the caller specified IB_SEND_FENCE in the send flags of the work request and no previous work request stated that the successive one should be fenced, the work request would be executed without a fence. This could result in RDMA read or atomic operations failure due to a MR being invalidated. Fix this by adding the mlx5 enumeration for fencing RDMA/atomic operations and fix the logic to apply this.
