The goal of commit 7987d2be5a8b ("virtio-net: Copy received header to buffer") was to remove the need to patch the (const) input buffer with a recomputed UDP checksum by copying headers to a RW region and inject the checksum there. The patch computed the checksum only from the header fields (missing the rest of the payload) producing an invalid one and making guests fail to acquire a DHCP lease.Fix the issue by copying the entire packet instead of only copying the headers.
