The purpose of commit703eec1b24("virtio_net: fixing XDP for fully checksummed packets handling") is to record the flags in advance, as their value may be overwritten in the XDP case. However, the flags recorded under big mode are incorrect, because in big mode, the passed buf does not point to the rx buffer, but rather to the page of the submitted buffer. This commit fixes this issue. For the small mode, the commitc11a49d58a("virtio_net: Fix mismatched buf address when unmapping for small packets") fixed it.
