On control planes that allow changing the MAC address of the interface,
the driver must provide a MAC type to avoid errors such as:

idpf 0000:0a:00.0: Transaction failed (op 535)
idpf 0000:0a:00.0: Received invalid MAC filter payload (op 535) (len 0)

These errors occur during driver load or when changing the MAC via:
ip link set <iface> address <mac>

Add logic to set the MAC type before performing ADD/DEL operations.
Since only one primary MAC is supported per vport, the driver only needs
to perform ADD in idpf_set_mac().

Fixes: ce1b75d0635c ("idpf: add ptypes and MAC filter support")
