Subject: [PATCH iproute2 V2 0/9] devlink params nested multi-attribute values

From: Saeed Mahameed <saeedm@...dia.com>

v1->v2:
  - Rebased on latest devlink kernel API.
  - Use var attributes enum instead of dynamic attributes enum.

This patch series reworks devlink parameters and introduces support for nested
multi attributes values. It also adds support for showing and setting port
parameters with multi-attribute value data.

example:
     $ devlink dev param show pci/... name multi-value-param
        name multi-value-param type driver-specific
        values:
          cmode permanent value: 0,1,2,3,4,5,6,7

     $ devlink dev param set pci/... name multi-value-param \
            value 4,5,6,7,0,1,2,3 cmode permanent

Please look out for the downstream kernel patches that will be posted
immediately after this series.

Title: "[PATCH net-next V4 00/13] devlink, mlx5: Add new parameters for link management and SRIOV/eSwitch configurations"

Thanks,
Saeed
