Subject: [PATCH v2 4/4] net: kill unused macros from head file
These macros have been defined for several years since v2.6.12-rc2（tracing by git）,
but never be used. So remove them.
Signed-off-by: Shan Wei <shanwei@...fujitsu.com>

I can't find any magic number in net/ipv6/addrconf.c
can be replaced by RETRANS_TIMER.
