Subject: [net-next v2 08/16] i40e: move i40e_reset_vf
Date: Fri, 20 Dec 2013 08:45:57 -0800	[thread overview]
Message-ID: <1387557965-13241-9-git-send-email-jeffrey.t.kirsher@intel.com> (raw)
In-Reply-To: <1387557965-13241-1-git-send-email-jeffrey.t.kirsher@intel.com>

From: Mitch Williams <mitch.a.williams@intel.com>

The VF reset code will be refactored in future patches. Part of that
refactor required it to call i40e_alloc_vf_res and i40e_free_vf_res, so
the function must be moved. In order to make the future patches more
readable, we perform the function move here, with no other changes.
