+Subject: Revert "rtnetlink: Reject negative ifindexes in RTM_NEWLINK"
+
+From: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
+
+This reverts commit 69197b2b2a7bcf92b209490639316af5dc751cc0 which is
+commit 30188bd7838c16a98a520db1fe9df01ffc6ed368 upstream.
+
+It was improperly backported to 4.14.y, and applied to the wrong
+function, which obviously causes problems.  A fixed version will be
+applied as a separate commit later.
