Hi Jukka,

thanks for the info, I looked at the YAML files of other platforms
and eventually came across the "-netif:eth" switch. Once I had that
integrated, I had a bit of a fight against the QEMU system
configuration in conjunction with the UART pipe and SLIP drivers used
by the networking tests, I eventually came up with a configuration in
which both the UART console and the UART pipe driver work after
fixing a minor bug in one of the instantiation macros of the Xilinx
UART driver. Also, having the Ethernet controller driver perform
polling reads/writes to a PHY that is non-existent in QEMU doesn't
help the system booting. Fortunately, I had the PHY initialization as
an optional switch in the driver's Kconfig file right from the
start.

I don't have the exact number of tests performed available right now,
but after all those changes, running sanitycheck for the tests/net
branch resulted in a significant number of test cases being executed,
of which only 2 or 3 failed - the actual tests all passed, but the
test cases failed due to assertions. Obviously, more interfaces than
expected are being created, in particular for test cases involving
VLANs. I'll leave that branch as it is for now, as I'm currently
doing my research regarding the two test cases in tests/kernel that
currently fail.

Best regards,
Immo
