kay.sievers@vrfy.org 5d24c6ca36 [PATCH] cleanup netif handling and netif-dev.d/ events
Here we supress the dev.d/ execution if we didn't change a network
interface's name with a rule. This should solve the issue of two
running dhclients for the same interface, cause the
/etc/dev.d/net/hotplug.dev script that fakes the hotplug event runs
with every udevstart for every interface and fakes a second identical
hotplug event on bootup.

With this patch netif interfaces are no longer stored in the udevdb.
It is not needed, cause we don't have permissions or symlinks :) and
all information is available in sysfs.

This patch also moves the dev_d execution calls out of the
udev_add/udev_remove. As with the former api-cleanup-patch we have
all processed data in one udev struct and can place the execution
calls where needed.
