net: ccwgroup: forward port changes from baselayout-1
Quite a bit of work happened in baselayout-1 on the ccwgroup module, but seems it didn't make it into openrc. So forward port all the existing code so we can work with more than just qeth and layer2 options. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
