2019-12-17ip: Protocol Independent IP NeighborsNeale Ranns1-2/+2
Type: feature - ip-neighbour: generic neighbour handling; APIs, DBs, event handling, aging - arp: ARP protocol implementation - ip6-nd; IPv6 neighbor discovery implementation; separate ND, MLD, RA - ip6-link; manage link-local addresses - l2-arp-term; events separated from IP neighbours, since they are not the same. vnet retains just enough education to perform ND/ARP packet construction. arp and ip6-nd to be moved to plugins soon.

2019-11-05misc: Fix python scripts shebang lineRenato Botelho do Couto1-1/+1
Type: fix Since CentOS 8, RPM build script doesn't accept '#!/usr/bin/env python' as a valid shebang line. It requires scripts to explicitly chose between python2 or python3. Change all to use python3 as suggested by Paul Vinciguerra.

2016-12-23make test: improve handling of packet capturesKlement Sekera1-10/+7
Perform accounting of expected packets based on created packet infos. Use this accounting info to automatically expect (and verify) the correct number of packets to be captured. Automatically retry the read of the capture file if scapy raises an exception while doing so to handle rare cases when capture file is read while only partially written during busy wait. Don't fail assert_nothing_captured if only junk packets arrived. Change-Id: I16ec2e9410ef510d313ec16b7e13c57d0b2a63f5 Signed-off-by: Klement Sekera <ksekera@cisco.com>
