From 69de9488991b9d3e3df7f9204884b11324cb6eeb Mon Sep 17 00:00:00 2001 From: Sunil Kumar Kori Date: Wed, 30 Oct 2019 21:56:44 +0530 Subject: [PATCH] examples/l2fwd-event: add infra to split eventdev framework Add infra to split eventdev framework based on event Tx adapter capability. If event Tx adapter has internal port capability then we use `rte_event_eth_tx_adapter_enqueue` to transmitting packets else we use a SINGLE_LINK event queue to enqueue packets to a service core which is responsible for transmitting packets.
