While fuzzing virtio-net I found that attempting to send a zero-size packet leads to an assertion failure, when resetting the device. These patches add an assertion to net/net.c to ensure that virtual devices do not try to send zero-size packets and change virtio-net to check that packets have non-zero size, prior to sending.
