3.6.11.1 stable review patch. If anyone has any objections, please let me know. ------------------ From: Marcelo Ricardo Leitner [ Upstream commit bd30e947207e2ea0ff2c08f5b4a03025ddce48d3 ] They will be created at output, if ever needed. This avoids creating empty neighbor entries when TPROXYing/Forwarding packets for addresses that are not even directly reachable. Note that IPv4 already handles it this way. No neighbor entries are created for local input. Tested by myself and customer. Signed-off-by: Jiri Pirko Signed-off-by: Marcelo Ricardo Leitner Signed-off-by: David S.
