description:
Import dhcpcd-8.0.5 with the following changes:
* inet6: Fix default route not being installed
* DHCP: If root fs is network mounted, enable last lease extend
* man: Fix lint errors.
* DHCP: Give a better message when packet validation fails
* DHCP: Ensure we have enough data to checksum IP and UDP
The last change fixes a potential DoS attack introduced in dhcpcd-8.0.3 when
the checksuming code was changed to accomodate variable length IP headers.
