rtnetlink_send() is similar to rtnl_notify(), there is no need for two 
functions to do the same thing. we can remove rtnetlink_send() and 
modify rtnl_notify() to adapt more case.

Patch1: remove rtnetlink_send() modify rtnl_notify() to adapt 
more case in rtnetlink.
Path2,Patch3: Adjustment parameters in rtnl_notify().
Path4: rtnetlink_send() already removed, use rtnl_notify() instead 
of rtnetlink_send().

You can't break compilation in between patches. Each step of the series
(each patch) must be self-contained, build, and work correctly.
Otherwise bisection becomes a nightmare.

Please also post series as a thread (patches in reply to the cover
letter), it seems that patchwork did not group the patches correctly
here.
