Subject[PATCH 4.9 232/310] stmmac: fix ptp header for GMAC3 hw timestamp
Date
4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Mario Molitor <mario_molitor@web.de>


[ Upstream commit fd6720aefde06eacf17404eed2cad65c6ec103e1 ]

According the CYCLON V documention only the bit 16 of snaptypesel should
set.
(more information see Table 17-20 (cv_5v4.pdf) :
Timestamp Snapshot Dependency on Register Bits)
