Test system.
kernel is 2.6.0-test1-bk (Fri, July 25), talking to a 2.4.21 kernel
with IPSec backport. IPSec is tunnel mode, ESP and AH with AES and MD5
for phase 1 and phase 2. PFS is off. default lifetimes. no modules
loaded on 2.6 kernel.
Starting tetheral (intf going into promiscuous mode ?) triggers this
bug.
