From: Anders Berggren Date: Fri, 4 Feb 2011 07:32:32 +0000 (+0000) Subject: igb: fix hw timestamping X-Git-Tag: v2.6.39-rc1~468^2~24^2~1 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=673b8b70cfae2cd0428a8ab5647571521348549a;p=platform%2Fkernel%2Flinux-exynos.git igb: fix hw timestamping Hardware timestamping for Intel 82580 didn't work in either 2.6.36 or 2.6.37. Comparing it to Intel's igb-2.4.12 I found that the timecounter_init clock/counter initialization was done too early.
