Subject: [dpdk-dev] [PATCH v2 2/2] pdump: use dynamic logtype
Date: Fri,  8 Nov 2019 08:47:17 -0800	[thread overview]
Message-ID: <20191108164717.7708-3-stephen@networkplumber.org> (raw)
In-Reply-To: <20191108164717.7708-1-stephen@networkplumber.org>

The logtype USER1 should not be overloaded for library function.
Instead use a dynamic log type.
