no ethernet hotplug on Raspberry Pi 3B with current raspios

[jrfromfl]

Describe the bug
after booting the newest version of raspios (May 7th,2021) with a Pi3B without ethernet connection I can't connect to a local network via ETH anymore. Plugging in the ethernet cable will leave the LEDs on the plug dark, /sys/class/net/$interface/carrier=0.
Booting the same sd-card with a Pi4B works fine.

To reproduce
copy iso to sd card and boot with a Pi3B without plugged ethernet cable, than connect cable (switch/dhcp srv)

Expected behaviour
LEDs on eth plug start blinking, ip addr show lists a ip addr on ethernet interface, link is UP

Actual behaviour
LEDs stay dark, ip link show lists ethernet interface as DOWN, no ip addr

Additional context
I made the same test with the raspios version of Dec 10,2020 and it worked just fine.

[shawaj]

Possibly related to #4341

[morrisrob]

I am experiencing the same issue on our custom 3b boards after updating to the 5.10 kernel and have been looking for a solution. A couple of observations that I've made while troubleshooting this:

• I only experience the issue when plugged into some network switches. When connected to one my switches, it consistently works fine but when connected to a couple other switches, I experience this issue. With the switches where I am experiencing the issue, if I downgrade back to our previous 4.19 kernel that we were using, everything works fine, so this rules out an issue with the switches / cabling (I have tried multiple other ethernet cables). I have replicated this same test a number of times.

• When it is in this state, if I run 'ifconfig eth0 down', and then 'ifconfig eth0 up', I get back to a working state.

[jrfromfl]

I can confirm, that it works with some switches and with others it does not.
I did tests with a Netgear switch and a FritzBox router and plugging in the ethernet cable after boot didn't work.
I also tested with a D-Link switch and it worked fine.

I can also confirm, that 'ip link set eth0 down' followed by 'ip link set eth0 up' reactivates the network connection to the Netgear switch and also to the FritzBox router.

For us this is a critical issue, because headless systems, that are remotely controlled via network may not be connected to the network after a powerfail, when the switch or router needs more time to activate the network ports than the rpi needs to boot.

[pelwell]

I think I've got at least a workaround for this. It seems that link detection can take more than the allowed 640ms, but if the PHY driver is allowed to wait 1500ms then the link comes back up.

Can anyone here test this patch? I've had success on a 3B and a 2B with it (and not without it):

See #4598.

Can anyone here test this patch? I've had success on a 3B and a 2B with it (and not without it):

@pelwell Yes, this does look to resolve the issue on the custom 3b that I'm using. I have not been able to reproduce the issue after applying this patch. Thank you for your help with this.

[pelwell]

Thanks for the feedback. The patch will be in future releases.

Yesterday's firmware release (available via rpi-update) includes this fix.
