Each port uses different credit quanta based on port type specified using port configuration flags. Each port has separate quanta defined in dlb2_priv.h Producer and consumer ports will need larger quanta value to reduce number of credit calls they make. Workers can use small quanta as they mostly work out of locally cached credits and don't request/return credits often.
