Subject: [PATCH] tests: Check CQE compression cap before using it
|
|
|
3bcb62 |
|
|
|
3bcb62 |
Add a CQE compression capability check in mlx5 CQ tests before creating
|
|
|
3bcb62 |
a CQ. If the device does not support the requested CQE compression type,
|
|
|
3bcb62 |
the test will be skipped.
|
|
|
3bcb62 |
|
|

Fixes: 8aae7abe241c ("tests: Add mlx5 CQ tests")
