I m using Marvell 8-port ethernet switch in our customized T4240 board. The 4 ports of switch is connected to MAC5 , MAC6 , MAC9 and MAC10 of FMAN0 of T4240 processor.
Ethermet switch is configure to force SGMII link (working fine in u-boot).
Trying to port kernal 4.1-r0 of QorIQ-SDK-V2.0-20160527-yocto to our board, in which sdk_dpaa driver is configured to force SGMII.
fm_mac_adjust_link was get to force SGMII while usnig ifconfig commad
But still port fail to link up.
