Daniel Borkmann b08d99c0d0 Add support for NDA_FLAGS_EXT neighboring attribute
This allows to set NTF_EXT_MANAGED neighbor flag for managed neighbor
entries as per kernel commit 7482e3841d52 ("net, neigh: Add NTF_MANAGED
flag for managed neighbor entries"). The flag then indicates to the
kernel that the neighbor entry should be periodically probed for keeping
the entry in NUD_REACHABLE state iff possible.
