[U-Boot] [RFC PATCH v3 0/7] Initial IPv6 support

[Chris Packham]

From: Chris Packham <chris.packham at alliedtelesis.co.nz>

Now we have something functional. With this you can do something like
'setenv ipaddr6 3ffe::2' and 'ping6 3ffe::1' should work.

I seem to have a problem that when you send a ping6 for a non-existent
address that ends up stuck and the next non-ipv6 net operation tries to
resolve it. I suspect this is because the pending neighbor discovery
information isn't cleaned up properly.

I'm sending this out now because I'll be away at a conference next week
so probably won't have any time to work on this but I did want to say
"hey ping6 works". When I get back I'll start tackling tftp over ipv6.

Changes in v3:
 -Fix a what should have been a glaringly obvious omission that cause
  all addresses to be interpreted as 0. Made even stricter so
  that v6 addresses that start with numbers aren't accepted.
 -return -1 with the input string is null.

Changes in v2:
- use __be16/__be32
- add ipv6_addr_v4mapped and ipv6_addr_is_isatap inline functions
Changes in v3
- Add reviewed-by from Kim Phillips to "Initial net6.h"
- Add support for printing mapped and ISATAP addresses
