Subject: [dpdk-dev] [PATCH next 09/10] net/vhost: implement dynamic logging
Date: Wed, 25 Apr 2018 08:56:45 -0700	[thread overview]
Message-ID: <20180425155646.3627-10-stephen@networkplumber.org> (raw)
In-Reply-To: <20180425155646.3627-1-stephen@networkplumber.org>

Use dynamic log type (instead of PMD) in vhost.
