Hi, 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 and ETHTOOL_MSG_PREEMPT_SET.
