IB/mlx5: Use mlx5 core to create/destroy a DEVX DCT

2019-03-18T00:40:39+00:00

To prevent a hardware memory leak when a DEVX DCT object is destroyed without calling DRAIN DCT before, (e.g. under cleanup flow), need to manage its creation and destruction via mlx5 core. In that case the DRAIN DCT command will be called and only once that it will be completed the DESTROY DCT command will be called. Otherwise, the DESTROY DCT may fail and a hardware leak may occur. As of that change the DRAIN DCT command should not be exposed any more from DEVX, it's managed internally by the driver to work as expected by the device specification.

net/mlx5: Add interface to hold and release core resources

2018-11-12T20:20:29+00:00

Sometimes upper layers may want to prevent the destruction of a core resource for a period of time while work on that resource is in progress. Add API to support this. Signed-off-by: Moni Shoua Signed-off-by: Leon Romanovsky

net/mlx5: Set uid as part of QP commands

2018-09-25T06:52:39+00:00

Set uid as part of QP commands so that the firmware can manage the QP object in a secured way. That will enable using a QP that was created by verbs application to be used by the DEVX flow in case the uid is equal. Signed-off-by: Yishai Hadas Signed-off-by: Leon Romanovsky

IB/mlx5: Fix existence check for extended address vector

2017-07-24T14:41:01+00:00

The extended address vector is the highest bit in be32 variable, but it was compared with the lowest. This patch fixes the endianness of that check and removes already declared define.

net/mlx5: Introduce set delay drop command

2017-07-24T14:34:28+00:00

Add support to SET_DELAY_DROP command. This command will be used in downstream patches for delay packet drop. The timeout value should be indicated by delay_drop_timeout field. Packet processing will be delayed till timeout value passed or until more WQEs are posted. Setting this value to 0 disables the feature.

net/mlx5e: IPSec, Innova IPSec offload infrastructure

2017-06-27T13:36:47+00:00

Add Innova IPSec ESP crypto offload configuration paths. Detect Innova IPSec device and set the NETIF_F_HW_ESP flag. Configure Security Associations using the API introduced in a previous patch. Add Software-parser hardware descriptor layout Software-Parser (swp) is a hardware feature in ConnectX which allows the host software to specify protocol header offsets in the TX path, thus overriding the hardware parser. This is useful for protocols that the ASIC may not be able to parse on its own. Note that due to inline metadata, XDP is not supported in Innova IPSec.

net/mlx5e: Move and optimize query out of buffer function

2017-06-15T21:19:02+00:00

Move "query queue counter out of buffer" helper function out of qp.c to en_main.c, since mlx5e netdev driver is the only one to use it. Also allocate the output buffer on the stack instead of the heap, to reduce number of heap allocs on update_stats work.

net/mlx5e: IPoIB, Xmit flow

2017-04-17T15:08:31+00:00

Implement mlx5e's IPoIB SKB transmit using the helper functions provided by mlx5e ethernet tx flow, the only difference in the code between mlx5e_xmit and mlx5i_xmit is that IPoIB has some extra fields to fill (UD datagram segment) in the TX descriptor (WQE) and it doesn't need to have any vlan handling.
