Subject: [PATCH net-next 1/7] net: dsa: mv88e6xxx: provide printing macros
The mv88e6xxx driver accesses a port's netdev mostly for printing.
This is bad for 2 reasons: DSA and CPU ports do not have a netdev
pointer; it doesn't give us a correct picture of why a DSA driver might
need to access a port's netdev.
Introduce mv88e6xxx_{dbg,err,warn} macros to print messages with a
prefix containing the real switch name (not the compatible one),
as well as the switch and port indexes.
These are examples of output in dmesg with this patch:
[ 103.488407] Marvell 88E6352 1.6: DefaultVID set to 42
[ 103.562586] Marvell 88E6185 2.0: 802.1QMode set to Secure
[ 103.559690] Marvell 88E6390X 1.2: PortState set to Forwarding
