3.11.10.4 -stable review patch. If anyone has any objections, please let me know. ------------------ From: Ben Hutchings <bhutchings@xxxxxxxxxxxxxx> 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.
