> Subject: [PATCH] net/mlx5: fix eCPRI item value with mask
> When creating a flow with eCPRI item, the mask and the value are both
> needed in order to build the matching criteria.
> In the current implementation, the unused value bits clear operation
> was missed when filling the mask and value fields. For the value, the
> bits not required were not masked with the mask provided. Indeed,
> this action is not mandatory. But when creating a flow in the root
> table, the kernel driver got involved and a check would prevent this
> flow from being created. The same flow could be created successfully
> with the userspace rdma-core on the non-root tables.
> An AND operation needs to be added to clear the unused bits in the
> value when building the matching criteria. Then the same flow can be
> created successfully no matter with kernel driver or with rdma-core.
