[PATCH 4.9 232/310] stmmac: fix ptp header for GMAC3 hw timestamp
4.9-stable review patch. If anyone has any objections, please let me know. -- From: Mario Molitor[ Upstream commit fd6720aefde06eacf17404eed2cad65c6ec103e1 ] According the CYCLON V documention only the bit 16 of snaptypesel should set.
