Maciej Żenczykowski 7c62508d6b ipv6: adjust ndisc_is_useropt() to also return true for PIO 
commit 048c796beb6eb4fa3a5a647ee1c81f5c6f0f6a2a upstream.

The upcoming (and nearly finalized):
  https://datatracker.ietf.org/doc/draft-collink-6man-pio-pflag/
will update the IPv6 RA to include a new flag in the PIO field,
which will serve as a hint to perform DHCPv6-PD.

As we don't want DHCPv6 related logic inside the kernel, this piece of
information needs to be exposed to userspace.  The simplest option is to
simply expose the entire PIO through the already existing mechanism.

Even without this new flag, the already existing PIO R (router address)
flag (from RFC6275) cannot AFAICT be handled entirely in kernel,
and provides useful information that should be exposed to userspace
(the router's global address, for use by Mobile IPv6).

Also cc'ing stable@ for inclusion in LTS, as while technically this is
not quite a bugfix, and instead more of a feature, it is absolutely
trivial and the alternative is manually cherrypicking into all Android
Common Kernel trees - and I know Greg will ask for it to be sent in via
LTS instead...
