- icmp_responder: responds to ICMPv4 and ARP requests - loopback: connects two interfaces and sends a verification packet from master memif to slave memif where it is looped back - loopback (reverse path): reverses direction of packet in loopback application (slave memif to master memif) Type: refactor Signed-off-by: Jakub Grajciar <jgrajcia@cisco.com> Change-Id: Ie90aaa3367269408efb6c5d538ad5aa827432238 Signed-off-by: Dave Wallace <dwallacelf@gmail.com>
