IFF_HASH feature indicates that the tun supports
TUNSETHASHPOPULATION ioctl and can propagate the hash
data to the virtio-net packet.

The module never creates the bpf program with bpf_prog_create
so it shouldn't free it with bpf_prog_destroy.
The program is obtained by bpf_prog_get and should be freed
by bpf_prog_put. For BPF_PROG_TYPE_SOCKET_FILTER both
methods do the same but for other program types they don't.

According to the virtio specification if VIRTIO_NET_F_HASH_REPORT
feature acked the virtio-net header is extended to hold the hash
value and hash report type.

This program type can set skb hash value. It will be useful
when the tun will support hash reporting feature if virtio-net.

If the BPF program populated the hash in the skb the tun
propagates the hash value and hash report type to the
respective fields of virtio-net header.

User mode program calls this ioctl before loading of
BPF program to inform the tun that the BPF program has
extended functionality, i.e. sets hash value and returns
the virtqueue number in the lower 16 bits and the type
of the hash report in the upper 16 bits.

Existing TUN module is able to use provided "steering eBPF" to
calculate per-packet hash and derive the destination queue to
place the packet to. The eBPF uses mapped configuration data
containing a key for hash calculation and indirection table
with array of queues' indices.
