This is a note to let you know that I have just added a patch titled sfc: Rate-limit log message for PTP packets without a matching to the linux-3.11.y-queue branch of the 3.11.y.z extended stable tree which can be found at: http://kernel.ubuntu.com/git?p=ubuntu/linux.git;a=shortlog;h=refs/heads/linux-3.11.y-queue If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.11.y.z tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Luis ------ From 249304fb0293effae8f03466728ddd1a41480ad6 Mon Sep 17 00:00:00 2001 From: Ben Hutchings <bhutchings@solarflare.com> Date: Fri, 6 Dec 2013 22:10:46 +0000 Subject: sfc: Rate-limit log message for PTP packets without a matching timestamp event commit 35f9a7a380728a94d417e5824a866f969423ac83 upstream. In case of a flood of PTP packets, the timestamp peripheral and MC firmware on the SFN[56]322F boards may not be able to provide timestamp events for all packets. Don't complain too much about this.
