[U-Boot] [RFC PATCH v2 1/5] Initial net6.h

Chris Packham
2013-01-18T01:35:28Z

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

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
