ping6 error

[Takashi Hibi <hibi665@xxxxxxx>]

Hi all,

There are IPv6 addresses for which ping6 doesn't work.
The host has a global IPv6 address.

$ ping6 ff05::1    (site-local multicast address)
connect: Cannot assign requested address
$ ping6 fec0::1    (site-local address)
connect: Cannot assign requested address

Usagi kernel doesn't have this problem.
Is this an expected behavior? And why this happens?

Regards,
Takashi Hibi
