[PATCH net-next 12/13] net: dsa: mv88e6xxx: prefix Port IEEE Priority mapping macros
From: Vivien Didelot
Date: Mon Jun 12 2017 - 12:44:21 EST
For implicit namespacing and clarity, prefix the common Port IEEE
Priority Remapping registers macros with MV88E6095_PORT_IEEE_PRIO.
The 88E6390 family turned the 0x18 register into a single indirect
table, document that at the same time.
Document the register and prefer ordered hex masks values for all
Marvell 16-bit registers.
Also fix the following checkpatch checks with a temporary variable:
CHECK: Alignment should match open parenthesis
#65: FILE: drivers/net/dsa/mv88e6xxx/port.c:932:
+ err = mv88e6xxx_port_ieeepmt_write(chip, port,
+ MV88E6390_PORT_IEEE_PRIO_MAP_TABLE_INGRESS_PCP,
