    _______________________________________________________

Details:

Added validity check in lwIP stack ICMPv6 NDP implementation.

According to RFC 4861 (chapter 7.1.1) a neighbor solicitation message
which has its source IPv6 address set to the 'unspecified address'
(0::0) and has the ICMPv6 option 'Source Link-Layer Address' set must
be silently discarded.
