net: microchip: sparx5: Add VCAP rule debugFS support for the VCAP API
This add support to show all rules in a VCAP instance. The information shown is: - rule id - address range - size - chain id - keyset name, subword size, register span - actionset name, subword size, register span - counter value - sticky bit (one bit width counter) Signed-off-by: Steen Hegelund <steen.hegelund@microchip.com> Signed-off-by: David S. Miller <davem@davemloft.net>
