net: dsa: let switches specify their tagging protocol
In order to support the new DSA device driver model, a dsa_switch should be able to advertise the type of tagging protocol supported by the underlying switch device. This also removes constraints on how tagging can be stacked to each other. Signed-off-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
