Ethernet Briding broken on APM Mustang on v4.0-rc1

[Christoffer Dall]

Hi,

Configuring bridged networking on the APM Mustang platform doesn't work
on v4.0-rc1.  It works fine on v3.19-rc1.

When adding the interface to the bridge I get this error:

can't add eth0 to bridge br0: Invalid argument

Has anyone else seen this?

Other ARMv8 platforms don't seem to be affected by this.

Thanks,
-Christoffer
