For the record, netlink interface for pause parameters which is based on
existing ioctl and ethtool_ops is in mainline but not in v5.6. If there
is a consensus that it should be rethought, it might still be possible
to drop these two request types and come with a better API later (i.e.
in 5.8 or 5.9 cycle).
