Subject: [net-next 13/15] i40e/i40evf: use logical operators, not bitwise
Date: Wed, 17 Feb 2016 19:38:55 -0800 [thread overview]
Message-ID: <1455766737-11911-14-git-send-email-jeffrey.t.kirsher@intel.com> (raw)
In-Reply-To: <1455766737-11911-1-git-send-email-jeffrey.t.kirsher@intel.com>
From: Mitch Williams <mitch.a.williams@intel.com>
Mr. Spock would certainly raise an eyebrow to see us using bitwise
operators, when we should clearly be relying on logic. Fascinating.
