From 10ed1e0bd144b5c3a92ca0c8fd06eb80b80649e5 Mon Sep 17 00:00:00 2001 From: Jarod Wilson Date: Tue, 26 Jul 2016 14:25:35 -0400 Subject: e1000e: fix PTP on e1000_pch_lpt variants I've got reports that the Intel I-218V NIC in Intel NUC5i5RYH systems used as a PTP slave experiences random ~10 hour clock jumps, which are resolved if the same workaround for the 82574 and 82583 is employed, so set the appropriate flag2 in e1000_pch_lpt_info too.
