Message-Id: <E1ifSV8-0000b1-NW@rmk-PC.armlinux.org.uk> Date: Thu, 12 Dec 2019 17:43:46 +0000 From: Russell King <rmk+kernel@...linux.org.uk> To: Andrew Lunn <andrew@...n.ch>, Florian Fainelli <f.fainelli@...il.com>, Heiner Kallweit <hkallweit1@...il.com> Cc: Antoine Tenart <antoine.tenart@...tlin.com>, "David S. Miller" <davem@...emloft.net>, netdev@...r.kernel.org Subject: [PATCH net-next 3/3] net: mvpp2: update mvpp2 validate() implementation Fix up the mvpp2 validate implementation to adopt the same behaviour as mvneta: - only allow the link modes that the specified PHY interface mode supports with the exception of 1000base-X and 2500base-X. - use the basex helper to deal with SFP modules that can be switched between 1000base-X vs 2500base-X. This gives consistent behaviour between mvneta and mvpp2. This commit depends on "net: phylink: extend clause 45 PHY validation workaround" so is not marked for backporting to stable kernels.
