Subject: Re: [PATCH] net: phy: phy_ethtool_ksettings_set: Allow any supported speed
Date: Mon, 2 Dec 2024 14:20:17 +0500	[thread overview]
Message-ID: <73ca1492-d97b-4120-b662-cc80fc787ffd@cogentembedded.com> (raw)

Hello.

> What's your use-case to need >1G fixed-settings link ?

My hardware is Renesas VC4 board (based on Renesas S4 SoC), network driver is rswitch, PHY in question 
is Marvell 88Q3344 (2.5G Base-T1).

To get two such PHYs talk to each other, one of the two has to be manually configured as slave.
(e.g. ethtool -s tsn0 master-slave forced-slave).

This gets handled via driver's ethtool set_link_ksettings method, which is currently set to
phy_ethtool_ksettings_set().

Writing a custom set_link_ksettings method just to not error out when speed is 2500 looks ugly.
