====================
ethtool-netlink bug fixes

This series contains a few bug fixes for ethtool-netlink. These bugs are
specific for the netlink interface, and the legacy ioctl interface is
not affected. These patches aim to have the same behavior in
ethtool-netlink as in the legacy ethtool.

Please also see the sibling series for the userspace tool.
