From 0ede4a606af1778b24b84b7feed3c0bed2751a34 Mon Sep 17 00:00:00 2001 From: Jacob Keller Date: Tue, 22 May 2012 06:08:32 +0000 Subject: [PATCH] ixgbe: ptp code cleanup This patch fixes two minor nits from Richard Cochran. The first is a case of ambitious line wrapping that wasn't necessary. The second is to re-order the flag checks for PPS support. Previously, the hardware test was done first, and the interrupt flag test was done second. Now, test the interrupt flag and use the unlikely macro.
