doc/3RDPARTY (apply patch)
Update to dhcpcd-8.1.7 which fixes the following issues:
* Decode interface complex interface names eth0.100:2 eth0i100:2.
This allows us to ignore some virtual interfaces by default
* ARP: Report L2 header address on conflict for more clarity
* DHCP: Support jumbo frames (untested)
* DHCP6: Clean up old lease on failure to confirm/rebind, etc
* RA: Prefer older routers - fixes PR bin/54997
* INET6: Obscure prefixes are now calculated correctly
* macro logerr commands to allow an alternative logger
