With the current RX RED/DROP levels of 192/184 for CQE_RX, when packet incoming rate is high, LLC is getting polluted resulting in more cache misses and higher latency in packet processing. This slows down the whole process and performance loss. Hence reduced the levels to 224/216 (ie for a CQ size of 1024, Rx pkts will be red dropped or dropped when unused CQE are less than 128/160 respectively)
