Hi, Eric && David

When ping from a PC to a board (MIPS 32 core), because of socket limit,
ping echo will fail. But ICMP_MIB_OUTERRORS counter is not incremented.
In this case, "netstat -s" can not report these errors.

This patch will fix this problem. Now it is in the attachment. Please 
check it.

Best Regards!
