if_tun: add TUNSETVNETLE/TUNGETVNETLE
ifreq flags field is only 16 bit wide, so setting IFF_VNET_LE there has no effect: doesn't fit in two bytes. The tests passed apparently because they have an even number of bugs, all cancelling out. Luckily we didn't release a kernel with this flag, so it's not too late to fix this. Add TUNSETVNETLE/TUNGETVNETLE to really achieve the purpose of IFF_VNET_LE. This has an added benefit that if we ever want a BE flag, we won't have to deal with weird configurations like setting both LE and BE at the same time. IFF_VNET_LE will be dropped in a follow-up patch. Reported-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Michael S. Tsirkin <mst@redhat.com> Signed-off-by: David S.
