Subject: Re: [PATCH net-next v5] net: ethernet: fec: Replace interrupt driven MDIO with polled IO
Date: Sat, 15 Aug 2020 18:55:56 +0200 [thread overview]
Message-ID: <20200815165556.GA503896@workstation.tuxnet> (raw)
In-Reply-To: <20200502152504.154401-1-andrew@lunn.ch>
Hi,
this patch / commit f166f890c8 ("net: ethernet: fec: Replace interrupt
driven MDIO with polled IO") broke networking on i.MX6Q boards with
Marvell 88E1510 PHYs (Copper / 1000Base-T).
Reverting said commit fixes the problem.
We also reverted 7cdaa4cc4b ("net: ethernet: fec: prevent tx starvation
under high rx load") but that was just for the revert of the problematic
commit to apply cleanly on top of 5.8 / 5.8.1.
Best regards,
Clemens
