Subject: [dpdk-dev] [PATCH v1] vhost: dequeue zero copy with linear buffers
Date: Thu, 26 Mar 2020 08:03:48 +0000 [thread overview]
Message-ID: <20200326080349.4181-1-Sivaprasad.Tummala@intel.com> (raw)
Removed the linear buffer and zero_copy compatibility restriction.
Applications that requires packets contained in a single buffer
will enable linear buffer in vhost library. This restriction
is not allowing zero_copy mode for such cases.
