Description
Started Haiku in QEMU with this configuration:
qemu-system-x86_64 -hda haiku-nightly-anyboot.iso -cpu host -accel kvm -m 4G -machine q35 -usbdevice tablet
The thread if_config_tqg_0 from the kernel team uses 100% CPU and network switches to "no link"
Removing the "-machine q35" avoids the problem.

Yes, confirmed. With q35 the network controller is 8086:10D3. With "-nic model=e1000" it switches to 8086:100E and the problem disappears.

for help on using tickets.
Please check whether this produces an "e1000" or "e1000e" class device. If the latter, please use the appropriate flags (probably
-nic e1000) to see if switching to an "e1000" device fixes the problem.
