Subject: [PATCH net-next 0/3] Minor managed neighbor follow-ups

Minor follow-up series to address prior feedback from David and Jakub.
Patch 1 adds a build time assertion to prevent overflows when shifting
in extended flags, patch 2 is a cleanup to use NLA_POLICY_MASK instead
of open-coding invalid flags rejection and patch 3 rejects creating new
neighbors with NUD_PERMANENT & NTF_MANAGED. For details, see individual
patches. Will push out iproute2 series after that. Thanks!

Daniel Borkmann (3):
  net, neigh: Add build-time assertion to avoid neigh->flags overflow
  net, neigh: Use NLA_POLICY_MASK helper for NDA_FLAGS_EXT attribute
  net, neigh: Reject creating NUD_PERMANENT with NTF_MANAGED entries
