gre: Multipoint GRE fixes
Type: fix - the CLI was broken when a nh-table-id was present, since it overwrote the next-hop address - bouncing interface state stacked the adjacencies on the tunnel's destination (which is all zeros) - don't crash in the switch path if the interface has no hw-address Signed-off-by: Neale Ranns <neale@graphiant.com> Change-Id: I1ba9fdc9b2185899b753a2d40f23afa847a3ef4f
