Subject: [PATCH net-next v3 6/6] net: phy: c45: change genphy_c45_ethtool_[get|set]_eee to use EEE linkmode bitmaps
Date: Fri, 26 Jan 2024 23:17:44 +0100	[thread overview]
Message-ID: <6a7bb313-ebd3-4acf-91be-bca1f3ba50aa@gmail.com> (raw)
In-Reply-To: <c28077f6-74e2-42fc-b57e-9545816cc813@gmail.com>

Change genphy_c45_ethtool_[get|set]_eee to use EEE linkmode bitmaps.
This is a prerequisite for adding support for EEE modes beyond bit 31.
