net/devlink: Support querying hardware address of port function
PCI PF and VF devlink port can manage the function represented by
a devlink port.
Enable users to query port function's hardware address.
Example of a PCI VF port which supports a port function:
$ devlink port show pci/0000:06:00.0/2
pci/0000:06:00.0/2: type eth netdev enp6s0pf0vf1 flavour pcivf pfnum 0 vfnum 1
function:
hw_addr 00:11:22:33:44:66
$ devlink port show pci/0000:06:00.0/2 -jp
{
"port": {
"pci/0000:06:00.0/2": {
"type": "eth",
"netdev": "enp6s0pf0vf1",
"flavour": "pcivf",
"pfnum": 0,
"vfnum": 1,
"function": {
"hw_addr": "00:11:22:33:44:66"
}
}
}
}
