NetRxPkt: Account buffer with ETH header in IOV length
In case of VLAN stripping ETH header is stored in a separate chunk and length of IOV should take this into account. This patch fixes checksum validation for RX packets with VLAN header. Devices affected by this problem: e1000e and vmxnet3. Cc: qemu-stable@nongnu.org Signed-off-by: Dmitry Fleytman <dmitry@daynix.com> Signed-off-by: Jason Wang <jasowang@redhat.com>
