When testing latest linux-next on the ZII DTU I face the issue that no
traffic is flowing over the switch ports, even though in dmesg
everything looks good. Also PHY properly establishes the link.
With 4.20.10 I don't have the issue and with 5.0-rc6 also not.
However on 5.0-rc6 I got the following, also number of network
interrupts seems to be very high (few minutes after boot).
Any idea what's going on?
Andrew, IIRC you recently fixed some interrupt-related issue:
7ae710f9f8b2 ("gpio: vf610: Mask all GPIO interrupts")
But the description doesn't seem to match this trace.
