FPMP[15:0]
FPMP[15:0] sets the number of cell intervals between the insertion of consecutive Forward
PM cells into the cell stream. The minimum rate of transfer is 1 in 65535 cell intervals.
When FPMP[15:0] = 0x0000 back-to-back Fwd PM cells are possible, though unlikely. The
default is set to 1 in 32 cell intervals.
