Subject: [dpdk-dev] [PATCH] net/virtio: fix queue notify
Date: Tue, 11 Apr 2017 03:44:28 -0700 [thread overview]
Message-ID: <1491907468-68207-1-git-send-email-xiao.w.wang@intel.com> (raw)
According to spec, we should write virtqueue index into the notify
address, rather than 1. Besides, some HW backend may rely on the data
written to identify which queue need to serve.
Fixes: 6ba1f63b5ab0 ("virtio: support specification 1.0")
