David Ahern 4c3493689e iplink_vrf: Save device index from response for return code
A recent commit changed rtnl_talk_* to return the response message in
allocated memory so callers need to free it. The change to name_is_vrf
did not save the device index which is pointing to a struct inside the
now allocated and freed memory resulting in garbage getting returned
in some cases.

Fix by using a stack variable to save the return value and only set
it to ifi->ifi_index after all checks are done and before the answer
buffer is freed.

This is a set of utilities for Linux networking.

How to compile this.
--------------------
1. libdbm

arpd needs to have the berkeleydb development libraries. For Debian
users this is the package with a name like libdbX.X-dev.
DBM_INCLUDE points to the directory with db_185.h which
is the include file used by arpd to get to the old format Berkeley
database routines.  Often this is in the db-devel package.

2. make

The makefile will automatically build a config.mk file which
contains definitions of libraries that may or may not be available
on the system such as: ATM, ELF, MNL, and SELINUX.

3. To make documentation, cd to doc/ directory , then
   look at start of Makefile and set correct values for
   PAGESIZE=a4		, ie: a4 , letter ...	(string)
   PAGESPERPAGE=2	, ie: 1 , 2 ...		(numeric)
   and make there. It assumes, that latex, dvips and psnup
   are in your path.

4. This package includes matching sanitized kernel headers because
   the build environment may not have up to date versions. See Makefile
   if you have special requirements and need to point at different
   kernel include files.
