from the long list of affected OS, Windows is the only one which is
still vulnerable to the RA autoconfig flood. And this is an old attack.
The new attack is flooding with many route options. and to this Linux
could be vulnerable too, however it does not seem so. Here all OS
(excluding Windows, including Linux) have a maximum size for routing
entries (1024). Why *BSD etc. is then affected but not Linux I don't know.
(flood_router26 by default does both attacks at once, because the former
is more devasting for Windows)
