Subject: [net-next 10/13] i40evf: fix off-by-one
Date: Fri, 20 Jun 2014 00:49:45 -0700	[thread overview]
Message-ID: <1403250588-14356-11-git-send-email-jeffrey.t.kirsher@intel.com> (raw)
In-Reply-To: <1403250588-14356-1-git-send-email-jeffrey.t.kirsher@intel.com>

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

The loop in i40evf_get_rxfh_indir was only reading fifteen registers,
not all sixteen. Change the matching loop in i40evf_set_rxfh_indir at
the same time to make the code more consistent.
