[Impact]
RoCE disable feature was added to the kernel v5.5.
This feature was requested by Mellanox customers that use Ubuntu 20.04,
and it's a very high important to deliver this feature to the customers
in one of ubuntu 20.04 SRU.
[SHORT DESCRIPTION]
RoCE enablement state controls driver support for RoCE traffic.
When RoCE is disabled, there is no gid table, only raw ethernet QPs are supported and traffic on the well known UDP RoCE port is handled as raw ethernet traffic.
[Test Case]
To change RoCE enablement state a user must change the driverinit cmode value and run devlink reload.
User command examples:
- Disable RoCE::
$ devlink dev param set pci/0000:06:00.0 name enable_roce value false cmode driverinit
$ devlink dev reload pci/0000:06:00.0
- Read RoCE enablement state::
$ devlink dev param show pci/0000:06:00.0 name enable_roce
pci/0000:06:00.0:
name enable_roce type generic
values:
cmode driverinit value true
[Regression Potential]
This feature shouldn't affect the regression because it's only adding support for
RoCE enable/disable.
Also,
This feature was tested internally by Mellanox QA teams
those tests logs/results are private unfortunately i can't share it here
[Other Info]
Feature patchset:
94de879c28d8 IB/mlx5: Load profile according to RoCE enablement state
b5a498baf929 IB/mlx5: Rename profile and init methods
cc9defcbb8fa net/mlx5: Handle "enable_roce" devlink param
e90cde0d76f0 net/mlx5: Document flow_steering_mode devlink param
6c7295e13ffd devlink: Add new "enable_roce" generic device param
patctwork:
https://patchwork.ozlabs.org/cover/1192314/
userspace:
No userspace dependency on this. the feature uses the devlink
param functionality which already exists in UB20.04. |

userspace:
No userspace dependency on this. the feature uses the devlink
param functionality which already exists in UB20.04. |
[Impact]
RoCE disable feature was added to the kernel v5.5.
This feature was requested by Mellanox customers that use Ubuntu 20.04,
and it's a very high important to deliver this feature to the customers
in one of ubuntu 20.04 SRU.
[SHORT DESCRIPTION]
RoCE enablement state controls driver support for RoCE traffic.
When RoCE is disabled, there is no gid table, only raw ethernet QPs are supported and traffic on the well known UDP RoCE port is handled as raw ethernet traffic.
[Test Case]
To change RoCE enablement state a user must change the driverinit cmode value and run devlink reload.
User command examples:
- Disable RoCE::
$ devlink dev param set pci/0000:06:00.0 name enable_roce value false cmode driverinit
$ devlink dev reload pci/0000:06:00.0
- Read RoCE enablement state::
$ devlink dev param show pci/0000:06:00.0 name enable_roce
pci/0000:06:00.0:
name enable_roce type generic
values:
cmode driverinit value true
[Regression Potential]
This feature shouldn't affect the regression because it's only adding support for RoCE enable/disable.
Also, This feature was tested internally by Mellanox QA teams
those tests logs/results are private unfortunately i can't share it here
Test 5.4 Ubuntu kernels have also been tested by Mellanox and have been verified working.
