Subject: Re: Marvell switch port shows LOWERLAYERDOWN, ping fails
Date: Fri, 6 Aug 2021 16:46:08 -0700	[thread overview]

Andrew,

Using 5.13.8 resolves the LOWERLAYERDOWN issue I observed when bringing 
up a slave interface on 5.4.114. The interface comes up after a 
15-second delay, with the Marvell PHY driver reporting a downshift event:

Unfortunately, the single-port DSA configuration showcase example (from 
Documentation/networking/dsa/configuration.rst) still does not pass ICMP 
via the lan1 port:

root@dali:~# ping 192.0.2.2

Running tcpdump indicates ARP packets are sent to eth0, but the lan1 
link peer does not reply:

root@dali:~# tcpdump -i eth0

Finally, here's the DSA info printed during boot:
