dsa: mv88e6xxx: Set DSA mode based on chip abilities
Older devices only support a single DSA frame format, where as newer devices have two. Take this into account when configuring a DSA port. The port needs to be in plain old DSA mode, since this is a DSA link, where as the newer format can be used for the CPU port. Signed-off-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: David S.
