Title:
  kernel arp neighbor limits should be adjusted by l3 agent

Status in neutron:
  Expired

Bug description:
  The default neighbor limits can be quite low (1024) for a kernel that
  the l3 agent is running on. If the agent is serving hundreds of
  tenants, it can quite easily blow past this limit, causing contention
  for a spot in the ARP table (or neighbor table in IPv6) and network
  instability.

  The l3 agent should set a higher default to match the expectations of
  a node with an l3 agent on it.
