From: Jimmy Assarsson <jimmyassarsson@xxxxxxxxx> This patch series add hardware timestamp support to all devices supported by the kvaser_usb driver. The first patches resolves a known issue; "Hardware timestamps are not set for CAN Tx frames". I can't remember why this wasn't implemented in the first version of the hydra driver. Followed by, hardware timestamp support for leaf and usbcan based devices. The final patches are removing code used for selecting the correct ethtool and netdev ops. Note: This patch series depends on patch "can: kvaser_usb: Explicitly initialize family in leafimx..." [1].
