MAXPL[16:1]:
The Maximum Packet Length (MAXPL[16:0]) bits are used to set the maximum packet length.
MAXPL[0] is automatically set to logic 0. Packets larger than this length are marked with an
error. This Maximum Packet Length defaults to 1.5 Kbytes. The packet length used here is
defined as the number of bytes encapsulated into the POS frame excluding byte stuffing but
including the FCS. The default maximum packet length is 1536 octets. The maximum packet
length allowed is 128 Kbytes.
