Subject: [PATCH net] r8169: always autoneg on resume
Date: Sat, 29 Sep 2018 21:18:41 -0400
Message-ID: <1538270023.zutwcuc82n.astroid@alex-desktop.none> (raw)

This affects at least versions 25 and 33, so assume all cards are broken
and just renegotiate by default.

Fixes: a2965f12fde6 ("r8169: remove rtl8169_set_speed_xmii")
