The driver writes green_max into the multicast admission entry's
GAP_GRN_YEL field and 400 into SHARED_CEILING, while qca-ssdk puts
green_max in the ceiling and leaves the gaps at zero. Rename the fields
after the register and write the values where qca-ssdk does. Fill
MCAST_PRIORITY_MAPn on user ports so flooded traffic reaches all of a
port's multicast queues instead of class 0 only; the CPU port keeps its
reset map. Set PC_DROP_BYPASS so dropped frames spend no policer tokens,
and METER_CMPST_LENGTH to the 4 FCS bytes, both as qca-ssdk does.
Measured on IPQ8074: the first multicast entry reads ceiling 250 with zero
gaps, and a four-queue port's map reads 0, 1, 2, 3, 3, 3.
