The second condition needs to check ARP probes only The ACD is not properly implemented as described in RFC5227 ch. 2.1.1 The implementation incorrectly detects an IP conflict, if an ARP request is received for the target IP. The reason is that the current implementation checks for ARP requests instead of ARP probes. Signed-off-by: Andreas Huber <[email protected]> (cherry picked from commit 27d93f8)
