Subject: [PATCH iproute2 00/10] devlink params nested multi-attribute values

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

This patch series reworks devlink parameters and introduces support for nested
value attributes. 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

This series is based on the following devlink kernel patches:
https://lore.kernel.org/netdev/20250228021227.871993-1-saeed@kernel.org/

Thanks,
Saeed

Jiri Pirko (2):
  update kernel headers
  devlink: use dynamic attributes enum

Saeed Mahameed (8):
  devlink: param show: handle multi-attribute values
  devlink: param set: reuse cmd_dev_param_set_cb for port params set
  devlink: rename param_ctx to dl_param
  devlink: helper function to read user param input into dl_param
  devlink: helper function to compare dl_params
  devlink: helper function to put param value mnl attributes from
    dl_params
  devlink: helper function to parse param vlaue attributes into dl_param
  devlink: params set: add support for nested attributes values
