Subject: [BUG] mv88e6xxx: tx regression in v5.3
Date: Wed, 11 Dec 2019 11:48:57 +0200	[thread overview]
Message-ID: <87tv67tcom.fsf@tarshish> (raw)

Hi Andrew, Vivien,

Since kernel v5.3 (tested v5.3.15), the 88E6141 switch on SolidRun
Clearfog GT-8K stopped transmitting packets on switch connected
ports. Kernel v5.2 works fine (tested v5.2.21).

Here are the relevant kernel v5.3 log lines:

The Tx count on the lan1 interface increments, but the ARP packets don't
show on the network.

Do you have any idea?

Thanks,
baruch
