net - Support ping reply when processing net-loop
Add ICMP_ECHO_REQUEST packet support by responding with a ICMP_ECHO_REPLY. This permits the ping command to test the phy interface when the phy is put in loopback mode (typically by setting register 0 bit 14). It also allows the port to respond to an external ping when u-boot is processing some other net command (such as tftp). This is useful when tftp appears to hang.
