net: dsa: felix: add port policers
This patch is a trivial passthrough towards the ocelot library, which support port policers since commit 2c1d029a017f ("net: mscc: ocelot: Implement port policers via tc command"). Some data structure conversion between the DSA core and the Ocelot library is necessary, for policer parameters. Signed-off-by: Vladimir Oltean <vladimir.oltean@nxp.com> Signed-off-by: David S. Miller <davem@davemloft.net>
