This patch fixes some remaining issues in the mvpp2 driver for the 10GB support on port 0. These changes are: - Incorrect PCS configuration - Skip PHY configuration when no PHY is connected - Skip GMAC configurations if 10G SFI mode set Signed-off-by: Stefan Chulski <stefanc@marvell.com> Signed-off-by: Stefan Roese <sr@denx.de> Cc: Kostya Porotchkin <kostap@marvell.com> Cc: Nadav Haklai <nadavh@marvell.com> Cc: Joe Hershberger <joe.hershberger@ni.com> Acked-by: Joe Hershberger <joe.hershberger@ni.com>
