TI CPSW 2nd ethernet port is not working

Hi,

There are two things to consider: The two Ethernet ports must be connected to different network segments and the second port must be brought up manually. See http://processors.wiki.ti.com/index.php/Linux_Core_CPSW_User's_Guide#Dual_Standalone_EMAC_mode for details.

I am attaching the kernel log .
