Subject: [PATCH net-next 04/13] net: dsa: mv88e6xxx: prefix Port Switch ID macros
For implicit namespacing and clarity, prefix the common Switch ID
Register macros with MV88E6XXX_PORT_SWITCH_ID.
Document the register and prefer ordered hex masks values for all
Marvell 16-bit registers, this means shifting their values by 4.
