The Intel DPDK does not at present support interrupts for dropped packets. Only support for link status change interrupts are supported at this time, but since the basics are there, it is possible with a bit of work to add handling for other interrupts if so needed.

Hi Sharath,

In DPDK interrupts are disabled to eliminate the performance overhead.
Interrupts used only for link status change. So you can poll
rte_eth_stats_get and check struct rte_eth_stats for errors.

Hi Sharath,

Try rte_eth_stats_get, I think this should give you what you're

looking
