Subject: [PATCH 3/7] devlink: Adding high level dev perm config params

Extending DEVLINK_ATTR_PERM_CFG (permanent/NVRAM device configuration)
to include some high level device configuration settings:

DEVLINK_ATTR_PERM_CFG_DCBX_MODE: Data Center Bridging Exchange
(DCBX) protocol mode; use enum devlink_dcbx_mode.

DEVLINK_ATTR_PERM_CFG_RDMA_ENABLED: 1 to enable RDMA, 0 to disable.

DEVLINK_ATTR_PERM_CFG_MULTIFUNC_MODE: Configure multi-function
mode; use devlink_multifunc_mode.

DEVLINK_ATTR_PERM_CFG_SECURE_NIC_ENABLED: 1 to enable Secure NIC
functionality, 0 to disable.

DEVLINK_ATTR_PERM_CFG_IGNORE_ARI_CAPABILITY: 1 to ignore ARI
(Alternate Routing ID) interpretation, 0 to honor ARI.

DEVLINK_ATTR_PERM_CFG_LLDP_NEAREST_BRIDGE_ENABLED: 1 to enable
Link Layer Data Protocol (LLDP) on Nearest Bridge, 0 to
disable.

DEVLINK_ATTR_PERM_CFG_LLDP_NEAREST_NONTPMR_BRIDGE_ENABLED: 1 to
enable Link Layer Data Protocol (LLDP) on Non Two Port MAC
Relay (non-TPMR) Bridge, 0 to disable.

DEVLINK_ATTR_PERM_CFG_PME_CAPABILITY_ENABLED: 1 to enable Power
Management Events (PME) functionality, 0 to disable.

DEVLINK_ATTR_PERM_CFG_MAGIC_PACKET_WOL_ENABLED: 1 to enable
Magic Packet Wake on Lan using ACPI pattern, 0 to disable.

DEVLINK_ATTR_PERM_CFG_EEE_PWR_SAVE_ENABLED: 1 to enable Energy
Efficient Ethernet (EEE), 0 to disable.
