====================
ip: fix creation flags reported in RTM_NEWROUTE events

Netlink messages sent to user-space upon RTM_NEWROUTE events have their
nlmsg_flags field inconsistently set. While the NLM_F_REPLACE and
NLM_F_APPEND bits are correctly handled, NLM_F_CREATE and NLM_F_EXCL
are always 0.

This series sets the NLM_F_CREATE and NLM_F_EXCL bits when applicable,
for IPv4 and IPv6.

Since IPv6 ignores the NLM_F_APPEND flags in requests, this flag isn't
reported in RTM_NEWROUTE IPv6 events. This keeps IPv6 internal
consistency (same flag semantic for user requests and kernel events) at
the cost of bringing different flag interpretation for IPv4 and IPv6.
