3.13.11-ckt33 -stable review patch. If anyone has any objections, please let me know.
---8<------------------------------------------------------------
From: Sergei Shtylyov <sergei.shtylyov@xxxxxxxxxxxxxxxxxx>
commit 3e2309937f1e5d538ff13da5fb8de41196927c61 upstream.
For the little-endian SH771x kernels the driver has to byte-swap the RX/TX
buffers, however yet unset physcial address from the TX descriptor is used
to call sh_eth_soft_swap(). Use 'skb->data' instead...
Fixes: 31fcb99d9958 ("net: sh_eth: remove __flush_purge_region")
