Using macros does not let the compiler verifying about the type we are
providing, which usually give an error easier to understand.
Also, this will let the compiler deciding how to actually optimize
(inline or not) the code.

Disable IPv6 DAD and ND for IP address test as there is
no need to do neighbor discovery in the test. We also
would like to see network interface debugging and use
dummy L2 driver instead of ethernet one.

The earlier Kconfig entries for IPv6 DAD and ND were confusing.
This commit will clarify this so DAD is activated by
CONFIG_NET_IPV6_DAD and ND is activated by CONFIG_NET_IPV6_ND.
These are settings are enabled by default.
