[PATCH 3.16 191/370] sh_eth: R8A7740 supports packet shecksumming

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

commit 0f1f9cbc04dbb3cc310f70a11cba0cf1f2109d9c upstream.

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...
