[PATCH net] net: mvpp2: 10G modes aren't supported on all ports

From: Antoine Tenart
Date: Tue Dec 11 2018 - 11:33:11 EST


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")
