Subject: [dpdk-dev] [PATCH v4] examples/vhost: fix failure to launch dpdk-vhost
Date: Wed, 3 Nov 2021 14:17:19 +0000 [thread overview]
Message-ID: <20211103141719.221486-1-wenwux.ma@intel.com> (raw)
In-Reply-To: <20211015164832.8865-1-wenwux.ma@intel.com>
When the default max queue value of vhost is 128, dpdk-vhost will fail to
launch with a 40G i40e port due to the mbuf allocation of the port queue fails.
Therefore, we modify the default value of max queue from 128 to 512,
it will ensure that there are enough mbufs.
Fixes: 4796ad63ba1f ("examples/vhost: import userspace vhost application")
