[dpdk-dev] [PATCH 33/44] net/cnxk: add Rx queue interrupt enable/disable ops

[Nithin Dabilpuram]

From: Sunil Kumar Kori <skori at marvell.com>

Application may choose to enable/disable interrupts on Rx queues
so that application can select its processing if no packets are
available on queues for a longer period.
