[dpdk-dev] [PATCH] net/ice: enlarge ice RXQ rearm thresh to 64

We observe performance drop on ice AVX512 data path after stop and start by using testpmd. As CPU polling is faster in AVX512 path, L3 contested accesses is intensified when rxrearm_start is a random value after testpmd stop/start. Enlarge ICE_RXQ_REARM_THRESH to 64 to ease the contested asscesse
