From b1ce8ebd97bac8663366d2035e2211ccef0ed832 Mon Sep 17 00:00:00 2001 From: Nikhil Rao Date: Wed, 11 Oct 2017 03:51:32 +0530 Subject: [PATCH] eventdev: add PMD callbacks for eth Rx adapter The PMD callbacks are used by the rte_event_eth_rx_xxx() APIs to configure and control the ethernet receive adapter if packet transfers from the ethdev to eventdev is implemented in hardware.
