The fix should work fine. It is technically a workaround for the way checksums work in virtualised systems, and the unfortunate fact that some DHCP clients check checksums on packets where the hardware has checksum offload enabled. (This doesn't work due to an optimisation in the way QEMU treats packet checksums. You'll see the problem if your machine is running the VM on the same host as its DHCP server and the VM has a vulnerable client.)
Is that specific to DHCP clients, or does this issue affect UDP traffic in general?
