[PATCH 4.4 85/91] sh_eth: enable RX descriptor word 0 shift on SH7734

From: Greg Kroah-Hartman
Date: Fri Aug 04 2017 - 19:39:27 EST


4.4-stable review patch. If anyone has any objections, please let me know.

[ Upstream commit 71eae1ca77fd6be218d8a952d97bba827e56516d ]

The RX descriptor word 0 on SH7734 has the RFS[9:0] field in bits 16-25
(bits 0-15 usually used for that are occupied by the packet checksum).
Thus we need to set the 'shift_rd0' field in the SH7734 SoC data...
