Subject[PATCH 3.18 83/92] sh_eth: R8A7740 supports packet shecksumming
Date
3.18-stable review patch.  If anyone has any objections, please let me know.

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

From: Sergei Shtylyov <sergei.shtylyov@cogentembedded.com>


[ Upstream commit 0f1f9cbc04dbb3cc310f70a11cba0cf1f2109d9c ]

The R8A7740 GEther controller supports the packet checksum offloading
but the 'hw_crc' (bad name, I'll fix it) flag isn't set in the R8A7740
data, thus CSMR isn't cleared...
