commit 7347391 ('network-legacy: split off from network module')
splitted network function to network-legacy and removed check() function
of 40network. This caused 40network to be included even if network is
not needed.

If the network module obtained a lease using dhclient, NetworkManager
must be configured to use it too, otherwise it would obtain a different
lease (and could potentially break a connection to the network volume).
In kdump, if dump-target is ssh on ipv6, we need to sync until ipv6 addr
is ready. Currently ip=auto6/dhcp6 provides such function. But in 1st kernel,
it is hard to know whether the ipv6 addr is got by dhcpv6 or SLAAC.
E.g ifcfg-eth* contains DHCPV6C=yes direction, but there is no dhcpv6
server in the network, and then after the system is up, the user
echo 1 > /proc/sys/net/ipv6/conf/eth0/autoconf && accept_ra by manual
to obtain a ipv6 addr. Or vice.
So this patch suggests to make dhcpv6 as auto6 fallback

If no network related params are specific, but rd.neednet=1 is set,
the default initqueue action is to wait until one of the network
interfaces is marked as setup properly.
This also help with initqueue's race condition when the network interface
shows up late

The MTU is only being set on the slave devices and the MTU of the
bonding master is not being updated. This updates the bonding master and
also changes the MTU on the slaves as expected.
Signed-Off-By: Robert LeBlanc <robert@leblancnet.us>
Prior to this commit, the MTU setting was applied to a bond slave
interface. In older versions of the Linux kernel, this setting
propagated to the bond master and the other bond slaves associated with
the master. In recent versions of the kernel (observed in Linux 4.12),
increasing the MTU of a slave does not automatically increase the MTU of
the master. This allows for more flexibility but requires the MTU of
the master to be changed manually.
Ideally, the MTU setting should be applied to the bond master and the
setting will propagate to the bond slaves, since the slaves are required
to have a MTU that is greater than or equal to the bond master.
The dracut network module is only supposed to be used for wired interfaces
but if driver modules for wireless devices are wrongly copied, these will
be loaded and the available interfaces brought up.
If the rd.neednet=1 command line parameter is used, dhclient will attempt
to request an IP address for the interfaces and these requests will fail.
But other dracut modules that depend on the network to be settled, will
have to wait for the DHCP requests to timeout. Which can be a lot of time
since the dhclient default timeout value is 60 seconds.
Instead of trying to blacklist all possible kernel modules for wireless
devices, only bring up network interfaces if these are for wired devices.

We tell dhclient to name 121 option "classless-routes",
but in dhclient-script we parse classless_static_routes.
So either have to change the configuration or the script.
And since dhclient uses by default classless_static_routes,
let's change the configuration
Previously our dhclient-script expected that $new_classless_static_routes
will have all values separated by a whitespace. But at least on F25
dhclient will put there the destination descriptor in the same format
as it is used by ISC dhcp-server.
For example:
new_classless_static_routes=32.10.198.122.47 192.168.78.4
while our current code expects
new_classless_static_routes=32 10 198 122 47 192 168 78 4
So let's just accept both of these formats by adding "." to IFS.

"Classless Route Option Format"
removed copy&paste artifact "modify_routes add"
there is no modify_routes() function, and we simply want the output
of the parse function.

Commit cf376023e6 moved writing .resolv.conf and .override
after dhcp_do, because dhcp_do was overwriting .resolv.conf. But .override does not have
such problem and on the contrary dhcp_do reads .override file if it is present. So let\'s
move it back.
