Subject: [PATCH net] net: mvpp2: 10G modes aren't supported on all ports
Date: Tue, 11 Dec 2018 17:32:28 +0100 [thread overview]
Message-ID: <20181211163228.26130-1-antoine.tenart@bootlin.com> (raw)
The mvpp2_phylink_validate() function sets all modes that are
supported by a given PPv2 port. A recent change made all ports to
advertise they support 10G modes in certain cases. This is not true,
as only the port #0 can do so. This patch fixes it.
Fixes: 01b3fd5ac97c ("net: mvpp2: fix detection of 10G SFP modules")
