dhclient initqueue hook fix
setup_net is scheduled in initqueue, sometimes it does not get chance to run
So the default route will not be set properly
Add a check in initqueue/finished to resolve this issue.

We do not support renaming in the kernel namespace anymore (as udev does
that not anymore). So, if a user wants to use ifname, he has to rename
to a custom namespace. "eth[0-9]+" is not allowed anymore.
The patch, acfab373 - Handle upper case MAC addresses in ifname
option,takes care of only the MAC conversion to lower case in the
interface name. But the same has to be taken care for BOOTIF also.
This patch takes care of changing the BOOTIF to lower case.
Note that sed has been used in the patch instead of tr, as it is not
compulsion to install tr by dracut in the initramfs and may not be
available always.

Subject: [PATCH] Fixed BOOTIF for converting mac addr to lowercase
This patch adds support of vlan tagged bonding, for example,
bond0.2. In case of regression, I also tested bond0 and eth0.2,
all work fine.

"brd +" is not valid for ipv6. This causes the 'ip addr add' command to
fail with the message "Broadcast can be set only for IPv4 addresses".
So: don't use "brd +" for ipv6.
Don't try to be smarter than the admin configuring the machine.
Does also conflict with other methods trying to setup the interfaces,
like cmsifup.sh from the cms module.
A bridge device with only one underlying ethernet device is almost
useless, for sure we want to support a bridge with multiple
underlying devices.
This patch adds the support by extending <ethname> in the original
bridge= cmdline to a comma-separated list of ethernet interfaces.

Anaconda used arguments of the form:
ip=<ip> gateway=<gw> netmask=<nm>
for static IP configuration. So if we get a value for "ip" that's an IP
address, look for gateway= and netmask= and related args to fill in the
ip config vars.
rd.neednet could be removed, as we can check /tmp/net.ifaces.
After this patch, kdump can bring up the NIC without
rd.neednet.

ifenslave is an old tool, and could be dropped,
we can use the /sys interface.

Relax the rules for kdump, we don't specify netroot in kdump.

This patch adds basic vlan support in network module.
The cmdline syntax for vlan is:
vlan=<vlanname>:<phydevice>
for an example:
vlan=eth0.2:eth0
or
vlan=vlan2:eth0
See also patch 2/8.

This is obviously wrong, ifenslave instead of brctl is needed for bonding.

Another solution could be searching in directories found at
/etc/ld.so.conf.d/*.conf or adding a new parameter. Here is a patch
which adds a new --libdirs parameter, and also a new inst_libdir_file
function which will try to expand metacharacters on each lib
directory:
inst_libdir_file "libdevmapper-event-lvm*.so"
For NetworkManager to properly take over a NFS-root system, we need to
have the interface name(s) in /tmp/net.ifaces and save the dhclient
lease. This lets the ifcfg module do its magic.
save_netinfo should properly write out /tmp/net.ifaces when needed, and
copies the dhclient files into place.
This makes sure the network is active and ready to use during the
initqueue/online hook.
It also makes it so you can run setup_net repeatedly without causing
error messages.
The "online" hook runs whenever a network interface comes online (that
is, once it's actually up and configured).
The initqueue --env argument is used to set "$netif" to the name of the
newly-online network interface.
Add new functions: all_ifaces_up, get_netroot_ip, ip_is_local, ifdown,
setup_net, set_ifname, ibft_to_cmdline
Use them in netroot.sh and parse-ip-opts.sh.
There's also a couple little unrelated cleanups.
net-lib.sh is a library of useful functions for network stuff.
More things may get added/moved here in the future.

Current dracut network only will be setup when netroot is used. But there are
some cases we need network even without netroot. For example kdump will need
copy vmcore to remote machine via scp or nfs mount. OTOH, if we use dracut as
a recovery system the network is helpful even root is not a network device.
This implementation is based on the manually bring up method. Here add a kernel
cmdline argument rd.neednet. If rd.neednet is set dracut will bring up network
with ifup $INTERFACE -m. If netroot is used we still keep original behavior.

For kdump we need scp vmcore to remote machine, the nic to be used is
not limited to netroot one. we need a feature for manually bringing up
network interface. Also it is useful for emergency shell with
ssh-client for recovery or test purpose
I implement this by adding one argument to ifup script, user can use
`/sbin/ifup eth0 -m` to bring up eth0, note ifup will regard it a
manual operation for the nic specified in 1st argument if there's
the 2nd argument.
If same nic is used for netroot the 2nd argument will be ignored,
in this case we will leave netroot bring up it automatically to
avoid side effect. And in this case hooks such as kdump will need to
execute after netroot mounted.
`ifup eth0 -m` will create /tmp/net.eth0.manualup stamp file,
later dhclient-script can check this and pass $2 to netroot,
then netroot script will bring eth0 up
