Subject: [net-next 02/13] ixgbe: remove redundant if clause from PTP work
Date: Mon, 31 Mar 2014 16:34:48 -0700	[thread overview]
Message-ID: <1396308899-20926-3-git-send-email-jeffrey.t.kirsher@intel.com> (raw)
In-Reply-To: <1396308899-20926-1-git-send-email-jeffrey.t.kirsher@intel.com>

From: Jakub Kicinski <kubakici@wp.pl>

ptp_tx_skb is always set before work is scheduled,
work is cancelled before ptp_tx_skb is set to NULL.
PTP work cannot ever see ptp_tx_skb set to NULL.
