Subject: [PATCH net-next 0/3] bridge: neigh msg proxy and flood suppression support

From: Roopa Prabhu <roopa@...ulusnetworks.com>

This series implements arp and nd suppression in the bridge
driver for ethernet vpns. It implements rfc7432, section 10
https://tools.ietf.org/html/rfc7432#section-10
for ethernet VPN deployments. It is similar to the existing
BR_ARP_PROXY flag but has a few semantic differences to conform
to EVPN standard. In case of EVPN, it is mainly used to avoid flooding to
tunnel ports like vxlan/mpls. Unlike the existing flags it suppresses flood
of all neigh discovery packets (arp, nd) to tunnel ports.

Roopa Prabhu (3):
  bridge: add new BR_NEIGH_SUPPRESS port flag to suppress arp and nd
    flood
  neigh arp suppress first
  bridge: suppress nd messages from going to BR_NEIGH_SUPPRESS ports
