The 6390X family has 8 SERDES interfaces. When ports 9 and 10 are not using all their SERDES interfaces, the unused ones can be assigned to ports 2-8. Add support for interrupts from SERDES interfaces connected to these lower ports. Signed-off-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: David S. Miller <davem@davemloft.net>
