now be removed from DPDK.

 Deprecation Notices
 -------------------
 
-* build: The ``enable_kmods`` option is deprecated and will be removed in a future release.
-  Setting/clearing the option has no impact on the build.
-  Instead, kernel modules will be always built for OS's where out-of-tree kernel modules
-  are required for DPDK operation.
-  Currently, this means that modules will only be built for FreeBSD.
-  No modules are shipped with DPDK for either Linux or Windows.
-
 * kvargs: The function ``rte_kvargs_process`` will get a new parameter
   for returning key match count. It will ease handling of no-match case.
