description:
When the receive partial store and forward mode is activated,
the receiver will only begin to forward the packet to the external
AHB or AXI slave when enough packet data is stored in the SRAM packet buffer.
rx-watermark corresponds to the number of SRAM buffer locations,
that need to be filled, before the forwarding process is activated.
Width of the SRAM is platform dependent, and can be 4, 8 or 16 bytes.
