Subject: [PATCH v3 1/1] examples/l2fwd-jobstats: fix lock availability
Date: Tue, 30 Jul 2024 15:33:35 +0530	[thread overview]
Message-ID: <20240730100335.3734796-1-rkudurumalla@marvell.com> (raw)
In-Reply-To: <20240729061026.3729690-1-rkudurumalla@marvell.com>

This patch addresses the issue by introducing a delay
before acquiring the lock in the loop. This delay allows for better
availability of the lock, ensuring that show_lcore_stats() can
periodically update the statistics even when forwarding jobs are running.

Fixes: 204896f8d66c ("examples/l2fwd-jobstats: add new example")
Cc: stable@dpdk.org
