Subject: [net-next 14/17] fm10k: fix incorrect DIR_NEVATIVE bit in 1588 code
Date: Tue, 16 Jun 2015 06:47:25 -0700 [thread overview]
Message-ID: <1434462448-140563-15-git-send-email-jeffrey.t.kirsher@intel.com> (raw)
In-Reply-To: <1434462448-140563-1-git-send-email-jeffrey.t.kirsher@intel.com>
From: Jacob Keller <jacob.e.keller@intel.com>
The SYSTIME_CFG.Adjust Direction bit is actually supposed to indicate
that the adjustment is positive. Fix the code to align correctly with
hardware and documentation.
