Since ethtool is provided to assist users migrating from kernel ethtool/net_device_op based design to user-space DPDK device management. The ethtool API's are created to closely maintain its original interface, therefore this library depends on <linux/ethool.h>. To avoid pollute the existing ethdev interface, a new library is created. To minimize code replication and maintain closely 1:1 API definition with kernel space API, this interface is designed based upon available ethdev APIs and add additional dev_ops if it's necessary. >- There is no obvious interest (how is it supposed to be used?) There are already two acknowledge on this release. Earlier comment on this patch has that " ... The API's for ethtool like things are valuable ..." >- There is no update in the doc/ directory Need more guidance on that. >Other comments: >- the patches are not versioned There is version file. Not sure what do you mean "the patches are not versioned" >- the copyright starts in 2010 Will fix that. >I'm curious to understand how renaming rte_eth_dev_set_mtu() to >rte_ethtool_net_change_mtu() will help anyone. As described, this interface is designed to provide API closely to kernel space ethtool ops and net_device_op.
