Details:

A number of ICMPv6 Router Advertisement (RA) fields and option subfields are
neither 8-bits nor byte arrays. As a consequence, these values require the
appropriate ntohs or ntohl functions to properly interpret the values.

Failure to do so can result in DHCP client failures on IPv6-carrying networks
with routers issuing RAs with the MTU option field and an MTU of 1500 which is
otherwise interpretted as 3691315200.
