[ Upstream commit 006791772084383de779ef29f2e06f3a6e111e7d ]
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.
