Subject: [PATCH 2/3] net: macb: add port constant to fix __be16 warnings
Add a constant MACB_PORT_MASK to use instead of 0xffff when checking against
ipv4 address port numbers. This allows the use of the __be16 constant and
silences the following sparse warnings:
drivers/net/ethernet/cadence/macb_main.c:3458:40: warning: restricted __be16 degrades to integer
drivers/net/ethernet/cadence/macb_main.c:3458:69: warning: restricted __be16 degrades to integer
drivers/net/ethernet/cadence/macb_main.c:3511:21: warning: restricted __be16 degrades to integer
drivers/net/ethernet/cadence/macb_main.c:3511:50: warning: restricted __be16 degrades to integer
