| Subject: sh_eth: R8A7740 supports packet shecksumming |
| |
| 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... |
