Thanks.  In theory, Smatch is supposed to be able to parse this
correctly but do_setlink() is too complicated for Smatch.

net/core/rtnetlink.c:2824 do_setlink() warn: Function too hairy.  No more merges.

So then the callers think that ifm->ifi_index is not used and they don't
pass that information.  It's hard to know how to fix this...

regards,
dan carpenter
