Subject: [net-next v2 03/14] i40e: assign correct vector to VF
Date: Tue, 22 Oct 2013 07:22:26 -0700 [thread overview]
Message-ID: <1382451757-9817-4-git-send-email-jeffrey.t.kirsher@intel.com> (raw)
In-Reply-To: <1382451757-9817-1-git-send-email-jeffrey.t.kirsher@intel.com>
From: Mitch Williams <mitch.a.williams@intel.com>
Correct math error when assigning MSI-X vectors to VFs. The vectors-per-vf
value reported by the hardware already conveniently reports one less than the
actual value.
