i have a test use pkt-gen.c # start pthread > 1 netmap as receiver work on NETMAP_HW_RING mode. if i stop recv packet. system dmesg will show interrupt storm detected on "irq281:"; throttling interrupt source interrupt storm detected on "irq281:"; throttling interrupt source interrupt storm detected on "irq281:"; throttling interrupt source interrupt storm detected on "irq281:"; throttling interrupt source interrupt storm detected on "irq281:"; throttling interrupt source ...... i think this error may be with poll or 82599 device? if i not use NETMAP_NW_RING will be ok!help
