From bc7d4b0346d43ed64c81fed8be1c8139bcbf7682 Mon Sep 17 00:00:00 2001 From: Pavan Nikhilesh Date: Wed, 31 Mar 2021 14:59:59 +0530 Subject: [PATCH] eventdev: support Tx adapter event vector Add event vector support for event eth Tx adapter, the implementation receives events from the single linked queue and based on rte_event_vector::attr_valid transmits the vector of mbufs to a given port, queue pair.
