Some interfaces require that the DHCPOFFER message is sent via broadcast if they can't receive unicast messages before they've been configured with an IP address. E.g., s390 ccwgroup network interfaces operating in layer3 mode face this limitation. This can prevent the interfaces from receiving an IP address via DHCP, if the have been configured for layer3. To allow DHCP over such interfaces, we're introducing a new device property ID_NET_DHCP_BROADCAST which can be set for those. The networkd DHCP client will check whether this property is set for an interface, and if so will set the broadcast flag, unless the network configuration for the interface has an explicit RequestBroadcast setting. Besides that, we're adding a udev rule to set this device property for ccwgroup devices operating in layer3 mode, which is the case if the ID_NET_DRIVER property is qeth_l3. Supercedes #18829 |

Files in this directory contain configuration for systemd-udev.service, a daemon that manages symlinks to device nodes, permissions of devices nodes, emits device events for userspace, and renames network interfaces. See man:udev(7) for an overview of the configuration file format, and man:systemd-udevd.service(8) for a description of service itself. Use 'systemd-analyze cat-config udev/rules.d' to display the effective config.
