[PATCH] net: ipconfgi: add declaration for ic_addrservaddr

[Ben Dooks]

The symbol ic_addrservaddr is not static, but has no declaration
to match. Since the similar variables are all exported, add this
one to the header file as well.

This fixes the following warning:

net/ipv4/ipconfig.c:130:8: warning: symbol 'ic_addrservaddr' was not declared. Should it be static?

Well, how about making it actually static if it's only used
from ipconfig.c ?

The only reason is that I thought someone might want to
use it in the future. I have no particular insight though.

Usual policy is that if such thing is required, then it can be
exported along with the code that is making use of it from elsewhere.

Thanks,

Right.
