-Subject: [PATCH] Avoid assertion failure when unsolicited ARP response
- received
-
-We probably want a more explicit handling of the case where we get an
-ARP response to a request that we did not send (system's own, or another
-Nmap scan running at the same time). In any case, this ought to solve
-the crashes reported as #1797 and #1764.
