Subject: realtek PHY commit bbc4d71d63549 causes regression
Date: Sat, 17 Oct 2020 16:20:36 +0200
Message-ID: <CAMj1kXEEF_Un-4NTaD5iUN0NoZYaJQn-rPediX0S6oRiuVuW-A@mail.gmail.com> (raw)

Hello all,

I just upgraded my arm64 SynQuacer box to 5.8.16 and lost all network
connectivity. This box has a on-SoC socionext 'netsec' network
controller wired to a Realtek 80211e PHY, and this was working without
problems until the following commit was merged

commit bbc4d71d63549bcd003a430de18a72a742d8c91e
Author: Willy Liu <willy.liu@realtek.com>
Date:   Tue Sep 29 10:10:49 2020 +0800

net: phy: realtek: fix rtl8211e rx/tx delay config

It was backported to v5.8 as b9f0dcfbfc07719be7cc732cda4e609280704605

The commit log in question is a bit vague, as it does not explain what
is wrong with the commit it aims to fix, or what the changes are meant
to achieve.

Since it breaks h/w in the field, can we please revert it? (and
backport the revert?)

Regards,
Ard.
