description = """The host system is running DHCP via dnsmasq 2.88. QEMU 9.1 works properly and completes DHCP handshake. QEMU 9.2 fails the DHCP handshake after DHCPOFFER with "eth0: checksum failure from 10.2.83.1".

I found by bisecting that the issue was introduced by commit 7987d2be5a8bc3a502f89ba8cf3ac3e09f64d1ce "virtio-net: Copy received header to buffer". Reverting that commit on 9.2.0 corrects the issue."""
