Subject: [PATCH 2/7] devlink: Adding NPAR permanent config parameters

Extending DEVLINK_ATTR_PERM_CFG (permanent/NVRAM device configuration)
to include NPAR settings:

DEVLINK_ATTR_PERM_CFG_NPAR_NUM_PARTITIONS_PER_PORT: Number of NIC
Partitions (NPAR) per port.

DEVLINK_ATTR_PERM_CFG_NPAR_BW_IN_PERCENT: 1 if BW_RESERVATION and
BW_LIMIT is in percent; /0 if BW_RESERVATION and BW_LIMIT is in
100 Mbps units.

DEVLINK_ATTR_PERM_CFG_NPAR_BW_RESERVATION: Configures NPAR bandwidth
or weight reservation, in percent or 100 Mbps units, depending on
BW_IN_PERCENT.

DEVLINK_ATTR_PERM_CFG_NPAR_BW_RESERVATION_VALID: 1 to use
BW_RESERVATION setting, 0 to ignore.

DEVLINK_ATTR_PERM_CFG_NPAR_BW_LIMIT: Configures NPAR bandwidth or
weight limit, in percent or 100 Mbps units, depending on
BW_IN_PERCENT.

DEVLINK_ATTR_PERM_CFG_NPAR_BW_LIMIT_VALID: 1 to use BW_LIMIT
setting, 0 to ignore.
