I test the qemu build like this,
qemu-system-m68k -M q800 -m 512M -serial none -serial mon:stdio -g 800x600x4
-net nic,model=dp83932,addr=00:00:00:01:02:03
-net bridge,helper=/opt/qemu/libexec/qemu-bridge-helper,br=br0
-append "fbcon=font:ProFont6x11 console=tty0 console=ttyS0 ignore_loglevel"
-kernel vmlinux-4.14.157-mac-backport+
-initrd /mnt/loop/install/cdrom/initrd.gz
You can obtain this kernel binary from the linux-mac68k project on
sourceforge. (I usually use a mainline Linux build but it makes no
difference.)
I normally use a disk image with Debian/m68k SID rootfs but in this
example I've used the initrd that you can find on the Debian/m68k
installer ISO.
Once the guest starts, switch to a different virtual console and bring up
the SONIC:
<ctrl>-<a> <ctrl>-<a> <2>
# ip addr add dev eth0 192.168.65.2/24
# ip link set dev eth0 up
On the host, send a ping flood (with preload) to the guest:
# ifconfig br0 192.168.65.1/24
# ping 192.168.65.2 -f -l 20
The packet reception ("deaf sonic") issue is reproduced immediately.
This has been observed in both qemu-m68k and mainline qemu. See also,
