like dev->tbusy flag, but I preferred new variable, because
the semantics is different. One day, when hard_start_xmit
will be multithreaded we will have to use skb->encapsulation.

so that I had to set ARPHRD_IPGRE to a random value.
I have an impression, that Cisco could make something similar,
but this feature is apparently missing in IOS<=11.2(8).

I set up 10.66.66/24 and fec0:6666:6666::0/96 as virtual networks
with broadcast 224.66.66.66. If you have access to mbone, play with me :-)
