net: ethernet: Add helper for set_pauseparam for Asym Pause
ethtool can be used to enable/disable pause. Add a helper to configure the PHY when asym pause is supported. Signed-off-by: Andrew Lunn <andrew@lunn.ch> Reviewed-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
