Subject: [PATCH] app/testpmd: fix out-of-bound reference in offload config
Date: Thu, 20 Feb 2025 12:44:26 -0800	[thread overview]
Message-ID: <20250220204427.213965-1-stephen@networkplumber.org> (raw)

When configuring offloads, need to check the port id before
indexing into the ports[] array. This can easily be done
by moving the call to oh_dev_conf_get_print_err() to before
the checks for port stopped.

Fixes: c73a9071877a ("app/testpmd: add commands to test new offload API")
