[ ignore the WARN_ON()s - some mdb entries notified by the bridge seem
to be leaking ]
instead I am noticing that the internal PHYs of switch d0032004.mdio-mii:11 and
d0032004.mdio-mii:12 are failing in phy_request_interrupt() - request_threaded_irq()
returns -EINVAL.
I haven't studied yet why that is. This happens with arch/arm64/boot/dts/marvell/armada-3720-turris-mox.dts,
which doesn't describe the switch PHY interrupts in the DTS. I don't know more yet.
There's nothing worth mentioning in the boot log prior to my unbind/bind commands.
