Subject: [PATCH] sh_eth: enable RX descriptor word 0 shift on SH7734
Date: Wed, 04 Jan 2017 23:10:23 +0300	[thread overview]
Message-ID: <1893574.OD9Leu8Ck8@wasted.cogentembedded.com> (raw)

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")
Signed-off-by: Sergei Shtylyov <sergei.shtylyov@cogentembedded.com>

The patch is against DaveM's 'net.git' repo.
