Subject: [dpdk-dev] [PATCH 3/3] net/bonding: start ethdev prior to setting 8023ad flow
Date: Tue, 22 Jun 2021 11:25:30 +0200
Message-ID: <20210622092531.73112-4-xhavli56@stud.fit.vutbr.cz> (raw)
In-Reply-To: <20210622092531.73112-1-xhavli56@stud.fit.vutbr.cz>

When dedicated queues are enabled, mlx5 PMD fails to install RTE Flows
if the underlying ethdev is not started:
bond_ethdev_8023ad_flow_set(267) - bond_ethdev_8023ad_flow_set: port not started (slave_port=0 queue_id=1)
