Try to set the MTU of the parent Ethernet interface to match the
requested PPP MTU and MRU. This allows the negotiation of a PPP MTU
and MRU greater than 1492.
We switched to user-mode PPPoE client to work around a bug in kernel
PPPoE code that caused pppd not to be notified when the connection was
terminated with a PADT before the LCP Termination Request.
The kernel bug has now been fixed upstream with commit 287f3a943fef
"pppoe: Use workqueue to die properly when a PADT is received", queued
for v4.1.
Since the issue affected only very particular scenarios and could
somehow be solved with the right configuration (see bugzilla entry),
we can safely revert the patch and restore the use of kernel mode
PPPoE.
This reverts commit 7955806a02.

When a connection had static IP addresses, an early event
from plaform would clear them from priv->con_ip4_config.
Fix that, by don't initializing priv->con_ip4_config
before we commit the first time.

We'd be able to do so for already existing devices, but not for devices that
are added afterwards, since gudev is hardwired not to listen for events from
kernel.
Mount a private sysfs instance. Otherwise gudev sees the devices from the
parent netns as opposed to our netns.
We do, however need a writable /sys/devices subtree for testing the bridge
code. There doesn't seem to be any other way to get a writable subtree of a
read-only filesystem than remounting it with no parameters after the initial
mount. We use this to get a writable sysfs instance and then bindmount it so
that it fits properly in the sysfs hierarchy.

It could be that the device was removed and the default route manager holds the
last reference:

NM always prepends the list of DNS domains received through DHCP to
the search list in /etc/resolv.conf, overriding the DHCP-supplied DNS
domain search order. This behavior is not entirely correct since it
changes the search order provided by system administrators.
We cannot simply avoid adding the DNS domain list to the search list
because this would break some configurations that rely on the 'domain'
option to deliver the search list.
This patch modifies the behavior of DNS manager to:
- insert the DHCP-provided 'domain' at the end of 'searches' option
so that 'searches' is always preferred
- ignore 'domain' if 'searches' option exists and 'domain' is a
single domain

Instead of hacky stuff in the Manager, let plugins themselves indicate
which links should be ignored (because they are really child links that
are controlled by a different device that the plugin handles).
Ethernet, WiFi, and VLAN used the same implementation for initial address.
Ethernet and WiFi used the same implementation (and duplicated code) for
permanent MAC address, plus they both used ethtool in what should be
generic code, which is better done in the platform.
Instead of having a bunch of logic in the Manager for determining the
VLAN and Infiniband virtual interface names, move the type-specific
logic into the plugins themselves.
Instead of looping over all plugins and asking each plugin whether it
can handle a link or a connection, have them advertise the link and
connection types they support, and use that when creating new devices.
For existing devices, depending on the order that netlink sends interfaces to
us, the parent may be found after the VLAN interface and not be available when
the VLAN interface is constructed. Instead of failing construction, when a
NMDeviceVlan has no parent keep it unavailable for activation. Then have
the Manager notify existing devices when a new device is found, and let
NMDeviceVlan find the parent later and become available via that mechanism.
This doesn't apply to VLANs created by NM itself, because the kernel requires
a parent ifindex when creating a VLAN device. Thus this fix only applies to
VLANs created outside NetworkManager, or existing when NM starts up.
beb18050 made this code run for all devices instead of just ethernet
devices, which means any kind of connection gets compared to any
device. But only compatible connections should be considered.
