virtio: use current_data as l2_hdr_offset
Type: fix virtio transmit node uses header offsets to set the appropriate metadata for packet with offloads. But l2_hdr_offset is not correctly set by previous node(s). This patch makes use of curren_data field as l2_hdr_offset. Signed-off-by: Mohsin Kazmi <sykazmi@cisco.com> Change-Id: Id2f41a7650be45c9cc1ebacc7bec298be79bf218
