Subject: [dpdk-dev] [PATCH v2 1/3] raw/ioat: support multiple devices being tested
Date: Thu, 10 Sep 2020 17:47:14 +0100
Message-ID: <20200910164716.1011901-2-bruce.richardson@intel.com> (raw)
In-Reply-To: <20200910164716.1011901-1-bruce.richardson@intel.com>

The current selftest function uses a single global variable to track state
which implies that only a single instance can have the selftest function
called on it. Change this to an array to allow multiple instances to be
tested.
