Reset the stored ping IP address before entering a netloop with different protocol to ensure that it won't be interrupted by the received correct ICMP_ECHO_REPLY packet.
Signed-off-by: Marek Szyprowski m.szyprowski@samsung.com --- v2: - Moved the net_ping_ip reset to the beginning of the net_loop() if the protocol is not equal to PING. This is required, because the netretry feature of the network framework relies on the fact that the internal state of the commands is preserved between net_loop() calls.
