Subject: [PATCH 03/10] graph: check return value from rte_eth_dev_info_get
Date: Fri, 4 Oct 2024 09:21:50 -0700 [thread overview]
Message-ID: <20241004162418.52940-4-stephen@networkplumber.org> (raw)
In-Reply-To: <20241004162418.52940-1-stephen@networkplumber.org>
The data in rte_eth_dev_info is undefined if rte_eth_dev_info_get
returns an error. Handle the errors the same as previous error.
