Message-Id: <1390398820-5355-8-git-send-email-nikolay@redhat.com>

Subject: [PATCH net-next v2 07/25] bonding: convert fail_over_mac to use the new option API
This patch adds the necessary changes so fail_over_mac would use
the new bonding option API. Also fixes a trivial copy/paste error in
bond_check_params where the wrong variable was used for the error msg.
