Implemented RFC7527 Enhanced DAD.
IPv6 duplicate address detection can fail if there is some temporary
loopback of Ethernet frames. RFC7527 solves this by including a random
nonce in the NS messages used for DAD, and if an NS is received with
the
same nonce it is assumed to be a looped back DAD probe and is ignored.
RFC7527 is enabled by default. Can be disabled by setting both of
conf/{all,interface}/enhanced_dad to zero.

fixes
This doesn't apply to net-next, please respin.
Also, please format your signoffs correctly, there must be a space
between your name and the <> enclosed email address.
I always wonder why people elide spaces when formatting text, is
there a global shortage of space characters that I am unaware of?
