-// Quantize cvita packets to a configurable quantum value. o_tlast and 
-// i_tready will be held off until the entire quantized packet is xferred. 
-// If quantum is changed, it is the responsibility of the client to clear
-// this module. error is asserted if a packet is larger than the quantum
-// error can be reset by asserting reset or clear.
