[PATCH 3.16 180/370] sh_eth: enable RX descriptor word 0 shift on SH7734

[Ben Hutchings]

3.16.42-rc1 review patch.  If anyone has any objections, please let me know.

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

From: Sergei Shtylyov <sergei.shtylyov@xxxxxxxxxxxxxxxxxx>

commit 71eae1ca77fd6be218d8a952d97bba827e56516d upstream.

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...

Fixes: f0e81fecd4f8 ("net: sh_eth: Add support SH7734")
