Dpdk packet reception

[Rajasekhar Pulluru]

Hi Team,

Would like to know if dpdk has a select(fd)/epoll(fd) like mechanism to
wake-up the application (say rx-pthread) asynchronously upon packet
reception without enabling rxq interrupts?

I can't afford to lose a cpu-core polling continuously to check for packets
using rte_eth_rx_burst.And I only have 1 core to receive packets from
multiple ports.I don't want to use usleep of fixed timeout between
rte_eth_rx_burst api invocation, as it potentially could lead to packets
being rx-missed in 1 or more ports.

Thanks & Regards,
Rajasekhar
