Oops, just saw that bug #38153 was a duplicate to this one, but it included a patch...

Anyway, this one should be fixed now.

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.
