[kvm-ppc-devel] guest networking getting close

[Hollis Blanchard]

From this guest boot log (with "ip=dhcp", bridged to the real physical
network), it looks like we actually are receiving packets and delivering
them to the guest properly. I enabled all the NETIF_MSG_* flags in the
8139cp driver, which is where all that eth0 output is coming from.

Unfortunately the guest still doesn't like the packets it's getting
(just times out with DHCP requests), so something's still not happy...
but we're getting closer.
