Subject: [PATCH 1/6] app/eventdev: simplify signal handling and teardown
Date: Wed, 27 Apr 2022 02:44:07 +0530
Message-ID: <20220426211412.6138-1-pbhagavatula@marvell.com> (raw)

Remove rte_*_dev calls from signal handler callback.
Split ethernet device teardown into Rx and Tx sections, wait for
workers to finish processing after disabling Rx to allow workers
to complete processing currently held packets.
