Subject: [dpdk-dev] [PATCH v3 2/6] net/iavf: fix incorrect link status when speed is undefined
Date: Fri,  4 Sep 2020 07:29:03 +0000	[thread overview]
Message-ID: <20200904072907.10648-3-stevex.yang@intel.com> (raw)
In-Reply-To: <20200904072907.10648-1-stevex.yang@intel.com>

When PF is put in no-carrier state, iavf VFs will switch to
"in carrier" state due to a link up + a link speed set to 0
(default value if no speed detected).

To be consistent with linux drivers on which PF and VFs are in
same carrier state, updates a link status of VF only if link is up
and speed is different from undefined.

Fixes: 48de41ca11f0 ("net/avf: enable link status update")
