Has the definition of an IPv6 address and IPv6 header. It may make sense
to separate the v4 support from net.h (or to include this in net.h).

Signed-off-by: Chris Packham <chris.packham@alliedtelesis.co.nz>

Changes in v2:
 -use __be16/__be32
 -add ipv6_addr_v4mapped and ipv6_addr_is_isatap inline functions
