net/mlx5e: Avoid unbounded peer devices when unpairing TC hairpin rules

2018-10-01T17:58:00Z

If the peer device was already unbound, then do not attempt to modify it's resources, otherwise we will crash on dereferencing non-existing device.

net/mlx5: Eliminate query xsrq dead code

2018-03-30T23:16:17Z

1. This function is not used anywhere in mlx5 driver 2. It has a memcpy statement that makes no sense and produces build warning with gcc8 drivers/net/ethernet/mellanox/mlx5/core/transobj.c: In function 'mlx5_core_query_xsrq': drivers/net/ethernet/mellanox/mlx5/core/transobj.c:347:3: error: 'memcpy' source argument is the same as destination [-Werror=restrict] Fixes: 01949d0109ee ("net/mlx5_core: Enable XRCs and SRQs when using ISSI > 0") Reported-by: Arnd Bergmann Signed-off-by: Saeed Mahameed

mlx5_{ib,core}: Add query SQ state helper function

2018-03-28T00:17:28Z

Move query SQ state function from mlx5_ib to mlx5_core in order to have it in shared code. It will be used in a downstream patch from mlx5e. Signed-off-by: Eran Ben Elisha Signed-off-by: Saeed Mahameed

net/mlx5: Enable setting hairpin queue size

2018-01-19T20:41:32Z

Allow to specify the size of the hairpin queues along with the packet buffer data size from the core setup code. If the driver doesn't provide this, the FW applies proper value that matches the provided data size and a FW chosen RQ stride size. Signed-off-by: Or Gerlitz Signed-off-by: Saeed Mahameed

net/mlx5: Vectorize the low level core hairpin object

2018-01-19T20:41:32Z

Enhance the hairpin setup code at the core to support a set of N (RQ,SQ) pairs. This will be later used by the caller to set RSS spreading among the different RQs. Signed-off-by: Or Gerlitz Signed-off-by: Saeed Mahameed

net/mlx5: Hairpin pair core object setup

2018-01-09T05:40:48Z

Low level code to setup hairpin pair core object, deals with: - create hairpin RQs/SQs - destroy hairpin RQs/SQs - modifying hairpin RQs/SQs - pairing (rst2rdy) and unpairing (rdy2rst) Unlike conventional RQs/SQs, the memory used for the packet and descriptor buffers is allocated by the firmware and not the driver. The driver sets the overall data size (log). Signed-off-by: Or Gerlitz Signed-off-by: Saeed Mahameed

IB/mlx5: Support setting Ethernet priority for Raw Packet QPs

2016-01-21T17:01:09Z

When the user changes the Address Vector(AV) in the modify QP, he provides an SL. This SL should be translated to Ethernet Priority by taking the 3 LSB bits, and modify the QP's TIS according to this Ethernet priority.

IB/mlx5: Add Raw Packet QP query functionality

2016-01-21T17:01:09Z

Since Raw Packet QP is composed of RQ and SQ, the IB QP's state is derived from the sub-objects. Therefore we need to query each one of the sub-objects, and decide on the IB QP's state. Signed-off-by: Majd Dibbiny Reviewed-by: Matan Barak Signed-off-by: Doug Ledford

net/mlx5_core: Export transport objects

2016-01-21T17:01:08Z

To be used by mlx5_ib in the following patches for implementing RAW PACKET QP. Add mlx5_core_ prefix to alloc and delloc transport_domain since they are exposed now. Signed-off-by: Majd Dibbiny Reviewed-by: Matan Barak Signed-off-by: Doug Ledford
