4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Lars Persson <lars.persson@xxxxxxxx>
[ Upstream commit d461873272169a3fc3a8d155d7b1c92e9d97b419 ]
The offset inside the fragment was not used for the dma address and
silent data corruption resulted because TSO makes the checksum match.
Fixes: 077742dac2c7 ("dwc_eth_qos: Add support for Synopsys DWC Ethernet QoS")
