[ Upstream commit e60ee41aaf898584205a6af5c996860d0fe6a836 ]

A customer noticed RX path hang when MTU is changed on the fly while running heavy traffic with NCSI enabled for 5717 and 5719. Since 5720 belongs to same ASIC family, we observed same issue and same fix could solve this problem for 5720.
