net: dsa: mv88e6xxx: prefix Global Monitor Control macros
Prefix and document the Global Monitor Control Register macros (which became the Global Monitor & MGMT Control Register with 88E6390) and give a clear 16-bit registers representation. Use __bf_shf to get the shift value at compile time instead of adding new defined macros for it. Signed-off-by: Vivien Didelot <vivien.didelot@savoirfairelinux.com> Signed-off-by: David S.
