Subject: [PATCH 4.3 106/157] dwc_eth_qos: Fix dma address for multi-fragment skbs
4.3-stable review patch. If anyone has any objections, please let me know.
------------------
From: Lars Persson <lars.persson@...s.com>
[ 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")
