Subject: [dpdk-dev] [PATCH] vhost: fix vector filling for packed ring
Date: Tue, 23 Oct 2018 14:07:49 +0800 [thread overview]
Message-ID: <20181023060749.25194-1-tiwei.bie@intel.com> (raw)
We should return the length of the buffers described by
the current descriptor chain after filling the buffer
vector. So we need to zero the *len first.
Fixes: 2f3225a7d69b ("vhost: add vector filling support for packed ring")
