Hi Roy,
That sounds great! There is only the problem, i am unable to compile dhcpcd. I've tried to emerge the 9999-ebuild with Gentoo.
It fails with:

/usr/bin/x86_64-pc-linux-gnu-gcc  -o dhcpcd common.o control.o dhcpcd.o duid.o eloop.o if.o if-options.o script.o dhcp-common.o dhcpcd-embedded.o if-linux.o if-linux-wireless.o arp.o dhcp.o ipv4.o ipv4ll.o ipv6.o ipv6nd.o dhcp6.o auth.o compat/arc4random.o compat/closefrom.o compat/strlcpy.o hmac_md5.o md5.o
if-linux.o: In function `link_netlink':
