net/mlx5e: Add support to klm_umr_wqe

2025-08-28T14:24:02+00:00

[ Upstream commit d7b896acbdcb3ef5dab1fd2f33ba5a8da6ba1dda ]

This commit adds the needed definitions for using the klm_umr_wqe.
UMR stands for user-mode memory registration, is a mechanism to alter
address translation properties of MKEY by posting WorkQueueElement
aka WQE on send queue.
MKEY stands for memory key, MKEY are used to describe a region in memory that
can be later used by HW.
KLM stands for {Key, Length, MemVa}, KLM_MKEY is indirect MKEY that enables
to map multiple memory spaces with different sizes in unified MKEY.
klm_umr_wqe is a UMR that use to update a KLM_MKEY.
SHAMPO feature uses KLM_MKEY for memory registration of his header buffer.

net/mlx5: Add priorities for counters in RDMA namespaces

2025-01-23T16:15:59+00:00

[ Upstream commit b8dfed636fc6239396c3a2ae5f812505906cf215 ]

Add additional flow steering priorities in the RDMA namespace.
This allows adding flow counters to count filtered RDMA traffic and then
continue processing in the regular RDMA steering flow.

net/mlx5: E-Switch, properly handle ingress tagged packets on VST

2023-01-12T10:59:11+00:00

[ Upstream commit 1f0ae22ab470946143485a02cc1cd7e05c0f9120 ]

Fix SRIOV VST mode behavior to insert cvlan when a guest tag is already
present in the frame. Previous VST mode behavior was to drop packets or
override existing tag, depending on the device version.

In this patch we fix this behavior by correctly building the HW steering
rule with a push vlan action, or for older devices we ask the FW to stack
the vlan when a vlan is already present.

net/mlx5: Allocate individual capability

2021-08-11T18:14:33+00:00

Currently mlx5_core_dev contains array of capabilities. It contains 19
valid capabilities of the device, 2 reserved entries and 12 holes.
Due to this for 14 unused entries, mlx5_core_dev allocates 14 * 8K = 112K
bytes of memory which is never used. Due to this mlx5_core_dev structure
size is 270Kbytes odd. This allocation further aligns to next power of 2
to 512Kbytes.

By skipping non-existent entries,
(a) 112Kbyte is saved,
(b) mlx5_core_dev reduces to 8KB with alignment
(c) 350KB saved in alignment

In future individual capability allocation can be used to skip its
allocation when such capability is disabled at the device level. This
patch prepares mlx5_core_dev to hold capability using a pointer instead
of inline array.

net/mlx5: Reorganize current and maximal capabilities to be per-type

2021-08-11T18:14:32+00:00

In the current code, the current and maximal capabilities are
maintained in separate arrays which are both per type. In order to
allow the creation of such a basic structure as a dynamically
allocated array, we move curr and max fields to a unified
structure so that specific capabilities can be allocated as one unit.

net/mlx5e: RX, Add checks for calculated Striding RQ attributes

2021-04-20T03:17:09+00:00

Striding RQ attributes below are mutually dependent. An unaware
change to one might take the others out of the valid range derived
by the HW caps:
- The MPWQE size in bytes
- The number of strides in a MPWQE
- The stride size

Add checks to verify they are valid and comply to the HW spec
and SW assumptions/requirements.
This is not a fix, no particular issue exists today.
