Subject: [net-next 08/15] i40e: Use consistent type for vf_id
Date: Sun, 1 May 2016 17:06:14 -0700 [thread overview]
Message-ID: <1462147581-135254-9-git-send-email-jeffrey.t.kirsher@intel.com> (raw)
In-Reply-To: <1462147581-135254-1-git-send-email-jeffrey.t.kirsher@intel.com>
From: Jesse Brandeburg <jesse.brandeburg@intel.com>
The driver was all over the place using signed or unsigned types
for vf_id, when it should always be signed.
This fixes warnings of type unsafe comparisons from gcc with W=2.
