Subject: [PATCH net-next 1/5] net: mii: convert mii_lpa_to_ethtool_lpa_x() to linkmode variant
Date: Wed, 11 Mar 2020 12:07:20 +0000	[thread overview]
Message-ID: <E1jC08u-0001cD-I6@rmk-PC.armlinux.org.uk> (raw)
In-Reply-To: <20200311120643.GN25745@shell.armlinux.org.uk>

Add a LPA to linkmode decoder for 1000BASE-X protocols; this decoder
only provides the modify semantics similar to other such decoders.
This replaces the unused mii_lpa_to_ethtool_lpa_x() helper.
