Message-Id: <1328922274-23993-1-git-send-email-greearb@candelatech.com> Date: Fri, 10 Feb 2012 17:04:18 -0800 From: greearb@...delatech.com To: netdev@...r.kernel.org Cc: Ben Greear <greearb@...delatech.com> Subject: [PATCH v3 00/16] Low-level Ethernet debugging features. From: Ben Greear <greearb@...delatech.com> This patch series enables some features designed to make testing ethernet devices and debugging link-level errors easier. First, support is added for receiving the Ethernet FCS. This allows stock wireshark to show you the actual Ethernet FCS. Second, allow sending packets with user-specified Ethernet FCS. The user can specify bad FCS in order to test network equipments' handling of FCS errors, or, in strange cases, users might want to implement their own FCS scheme. Third, allow configuring a NIC to receive errored (and possibly other types of packets not normally passed up the stack). This allows sniffers to show packets with bad FCS, for instance. Changes from V2: * Fix e100 to properly not count the FCS in the rx-bytes counter. * Add rx-fcs and rx-all support for e1000 driver (tested with bad FCS pkts). * Add realtek 8139too and r8169 support for rx-all and rx-fcs features. It appears these drivers cannot do per-packet FCS tx config, so I have no plans to implement the 'send custom fcs' logic in them.
