Subject: [PATCH v2] app/testpmd: fix secondary process not forwarding
Date: Tue, 21 Feb 2023 15:44:18 +0000	[thread overview]
Message-ID: <20230221154418.153972-1-shiyangx.he@intel.com> (raw)
In-Reply-To: <20221230075554.25244-1-shiyangx.he@intel.com>

Under multi-process scenario, the secondary process gets queue state
from the wrong location (the global variable 'ports'). Therefore, the
secondary process can not forward since "stream_init" is not called.

This commit fixes the issue by calling 'rte_eth_rx/tx_queue_info_get'
to get queue state from shared memory.

Fixes: 3c4426db54fc ("app/testpmd: do not poll stopped queues")

v2: Add function return value processing
