commit: https://git.buildroot.net/buildroot/commit/?id=84d997d6890f1d045c4d6084148fd9b2d674a6c7
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master
Allow automatic network configuration via systemd-networkd if selected.
If systemd-networkd is enabled and $BR2_SYSTEM_DHCP is set, then create
a .network file to configure the selected network interface via DHCP.

[Thomas:
- merge the two patches from Eric into just one
- instead of generating the dhcp.network file completely from the .mk
file, use a template file, and "sed" it with the right network
interface]

Sorry, forgot to "git add" it. I even did a test build before pushing
to make sure it was all building fine... but forgot to git add. I've
fixed that in a follow-up commit. Thanks for noticing!
