Subject: [PATCH] inet.xml: fix invalid IPv4-mapped-address examples

* IPv6 address FFFF::192.168.42.2 is an invalid form as an IPv4-mapped address.
  This should be fixed as ::FFFF:192.168.42.2.
  The assigned address block is ::ffff:0:0/96.
  See RFC6890 Table 20 in the Section 2.2.2 for the further details.

And for this IPv4-mapped address use *only*,
  the 32bit LSB of the IPv6 address can be written
  with the respective IPv4 address.
  See RFC4291 Section 2.2 Form 3 for the further details.
