ip6-nd: support dump/details for IPv6 RA
Type: improvement With this change, add support for dumping IPv6 Router Advertisements details on a per-interface basis (or all). Also, cover that with a test. Signed-off-by: Alexander Chernavin <achernavin@netgate.com> Change-Id: I89fa93439d33cc36252377f27187b18b3d30a1d4
