Ethernet interface. This patch just increase the retries
to 20 times, to make it work for InfiniBand as well.

dhcp-all-interfaces

Autodetect network interfaces during boot and configure them for DHCP

The rationale for this is that we are likely to require multiple network interfaces for use cases such as baremetal and there is no way to know ahead of time which one is which, so we will simply run a DHCP client on all interfaces with real MAC addresses (except lo) that are visible on the first boot.

The script /usr/local/sbin/dhcp-all-interfaces.sh will be called early in each boot and will scan available network interfaces and ensure they are configured properly before networking services are started.
