Hi All, I would like to know your opinion regarding adding support for driver private ioctl's in ethtool.
Background: Synopsys Ethernet IP's have a certain number of features which can be reconfigured at runtime. Giving you two examples: One of the most recent one is the safety features, which can be enabled/disabled and forced at runtime. Another one is a Flexible RX Parser which can route specific packets to specific RX DMA channels. Given that these are features specific to our IP's it would not be useful to add an uniform API for this because the users would only be one or two drivers ... This new feature would change the help usage for ethtool so that each driver private option would be shown, and then each driver specific file would have a structure with all the available options. Finally, each driver would have to handle the private IOCTL's. We already have this working locally and now I would like to know your opinion about upstreaming this ... Do you think this can be useful for anyone else? Or should we change direction to use, for example, debugfs/configfs? Thanks and Best Regards, Jose Miguel Abreu
