bnx2fc doesn't _actually_ need fcoemon, so fipvlan is sufficient
to start the FCoE connection.
And, in fact, fcoemon is started for every interface, causing
subsequent invocations to fail with
fcoemon[1157]: error 98 address already in use
and fcoemon tearing down the connection.

fcoemon is well capable of figuring out whether a vlan should
be used, so there's no need to disable the AUTO_VLAN feature.

FCoE can run in Fabric (ie FCF) or VN2VN mode, so we should allowing
to set this parameter from the commandline, too.

If the installation already has a FCoE configuration we should
not attempt to overwrite it but rather use the pre-defined
configuration.

Check first if we're running off an bnx2x device and start FCoE on it
via fipvlan, then go the normal/Intel way of starting DCB.
Also the SUSE version of fcoemon needs the yes parameter for the
--syslog option

bnx2x can take no longer than 3 seconds to initialize the link in some setups
which can cause fipvlan to fail and thus the fcoe interface(s) won't be
created.
Add another 10 seconds to give the link enough time to initialize.

lldpad is a system-wide process, which must be started only once.
So we should be separate it from fcoe-up, as it might be called
several times.

DCB & fipvlan can only be called on real devices, not VLAN
ones. So skip any VLAN devices which might been added to the
list of network interfaces.

To start bnx2fc, we need to run fipvlan only and not dcbtool. DCBX is run
automatically in the hardware, but VLAN discovery needs to be started by
fipvlan.

We want all "/var/run" information to live in /dev/.run, until the real
root is mounted.
Therefore we mount a tmpfs on /dev/.run, which can/will be bind/move mounted
on /var/run later on.
Note that there are still some patches queued upstream for fcoe-utils to
enable it to work with the new lldpad and to add support to fipvlan to
bring up FCoE connections without requiring fcoemon to run.
The invocations of the various tools as in this patch should be final though,
see the discussion in:
http://bugzilla.redhat.com/show_bug.cgi?id=563794
This is the second revision of this patch, which no longer adds /etc/fcoe
to the initrd as that is not needed.
Supported cmdline formats:
fcoe=<networkdevice>:<dcb|nodcb>
fcoe=<macaddress>:<dcb|nodcb>
Note currently only nodcb is supported, the dcb option is reserved for
future use.
Note letters in the macaddress must be lowercase!
Examples:
fcoe=eth0:nodcb
fcoe=4A:3F:4C:04:F8:D7:nodcb
