dsa: Move tagger name into its ops structure
Rather than keep a list to map a tagger ops to a name, place the name into the ops structure. This removes the hard coded list, a step towards making the taggers more dynamic. Signed-off-by: Andrew Lunn <andrew@lunn.ch> Reviewed-by: Florian Fainelli <f.fainelli@gmail.com> v2: Move name to end of structure, keeping the hot entries at the beginning. Signed-off-by: David S. Miller <davem@davemloft.net>
