Miller" <davem@davemloft.net> Cc: linux-renesas-soc@vger.kernel.org, linux-sh@vger.kernel.org Subject: [PATCH 2/7] sh_eth: RX checksum offload support Date: Sun, 27 Jan 2019 17:37:33 +0000 [thread overview] Message-ID: <29cb4d33-37c3-43c0-3bce-fa01737c0fa4@cogentembedded.com> (raw) In-Reply-To: <fc43bfa2-4312-b52b-a749-e3e43e242a95@cogentembedded.com> Add support for the RX checksum offload. This is enabled by default and may be disabled and re-enabled using 'ethtool': # ethtool -K eth0 rx {on|off} Some Ether MACs provide a simple checksumming scheme which appears to be completely compatible with CHECKSUM_COMPLETE: sum of all packet data after the L2 header is appended to packet data; this may be trivially read by the driver and used to update the skb accordingly. The same checksumming scheme is implemented in the EtherAVB MACs and now supported by tha 'ravb' driver. In terms of performance, throughput is close to gigabit line rate with the RX checksum offload both enabled and disabled. The 'perf' output, however, appears to indicate that significantly less time is spent in do_csum() -- this is as expected.
