Subject: [PATCH 19.11 1/4] app/testpmd: fix port status of bonding slave device
Date: Tue, 19 Jul 2022 10:49:16 +0800	[thread overview]
Message-ID: <20220719024919.16999-2-lihuisong@huawei.com> (raw)
In-Reply-To: <20220719024919.16999-1-lihuisong@huawei.com>

[ upstream commit e46372d7b082706718bb17981ae632e4e4d56414 ]

Starting or stopping a bonded port also starts or stops all active slaves
under the bonded port. If this port is a bonded device, we need to modify
the port status of all slaves.

Fixes: 0e545d3047fe ("app/testpmd: check stopping port is not in bonding")
