Subject: [ethtool RFC 0/3] ethtool: Add support for frame preemption


This is the userspace side of the series proposing an interface via
ethtool for configuring frame preemption, defined in IEEE 802.1Q-2018
(previously IEEE 802.1Qbu) and 802.3br.

Patch 1 of this RFC is only to help testing, and should not be considered.

Patch 2, adds support for the ETHTOOL_GFP and ETHTOOL_SFP commands.

Patch 2, adds support for the netlink messages ETHTOOL_MSG_PREEMPT_GET
