-Subject: [PATCH] configure: Eliminate the hard-coded libnl-3 include path
-
-See also commit 3dde41998625fe0e24119a2e1f4509ba3ba2fd9a.
-
-(cherry picked from commit 852dcd644cfe4cfc7177649eaec163d6221f2be1)
-
-Original commit included modifications to configure script.
-Do not keep these modifications, since they caused lots of conflicts, and
-configure script is meant to be automatically generated.
