The NIC I use is "Marvell Technology Group Ltd. 88E8056 PCI-E Gigabit
Ethernet Controller", not Intel, with sky2 driver.

No, since everything was working fine (before I decided to test PCI
passthrough).

Not sure. Will check

It is packaged by openWRT Builroot. Just have to set the kernel version
I want to use.
Will try a vanilla kernel as soon as possible.

OK, will try it as well.
