#
# 7.1.1. Validation of Neighbor Solicitations
#
#
# A node MUST silently discard any received Neighbor Solicitation
# messages that do not satisfy all of the following validity checks:
#
#
# - The IP Hop Limit field has a value of 255, i.e., the packet
# could not possibly have been forwarded by a router.
#
#
# - If the message includes an IP Authentication Header, the message
# authenticates correctly.
#
#
# - ICMP Checksum is valid.
#
#
# - ICMP Code is 0.
#
#
# - ICMP length (derived from the IP length) is 24 or more octets.
#
#
# - Target Address is not a multicast address.
#
#
# - All included options have a length that is greater than zero.
#
#
# - If the IP source address is the unspecified address, the IP
# destination address is a solicited-node multicast address.
#
#
# - If the IP source address is the unspecified address, there is no
# source link-layer address option in the message.
