Send 64 bytes of zeroes packet with source XXXXXXXX:YYYYYYYYYYYY/0455 to
00000000:FFFFFFFFFFFF/0455 [sipx_type=0x14]. All machines which respond
and are not routers should be verified. And if broadcast storm does not
cease to exist in few seconds, it is time to visit your routers and
switches and hit poweroff button... And then ban all machines which
participated as senders of these frames...

Can't we use skb_unshare()?
