Description of problem:
I can't create more than one ethernet bonding interface.

It seems that the init scripts are written to handle the configuration of more
than one channel bonding interface. When i try to bring up the second bonding
interface, i get this error:

[root@vlxq01md net]# ifup bond1
bonding device bond1 does not seem to be present, delaying initialization.
[root@vlxq01md net]#

Here is my config:

/etc/modprobe.conf
alias eth2 bnx2
alias eth3 bnx2
alias eth0 e1000
alias eth1 e1000
alias scsi_hostadapter aacraid
alias scsi_hostadapter1 qla2xxx
alias bond0 bonding
alias bond1 bonding

/etc/sysconfig/network-scripts/ifcfg-bond0

/etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
ONBOOT=yes
BOOTPROTO=none
MASTER=bond0
SLAVE=yes
USERCTL=no

/etc/sysconfig/network-scripts/ifcfg-eth1
DEVICE=eth1
ONBOOT=yes
BOOTPROTO=none
MASTER=bond0
SLAVE=yes
USERCTL=no

/etc/sysconfig/network-scripts/ifcfg-eth2
DEVICE=eth2
ONBOOT=yes
BOOTPROTO=none
MASTER=bond1
SLAVE=yes
USERCTL=no

/etc/sysconfig/network-scripts/ifcfg-eth3
DEVICE=eth3
ONBOOT=yes
BOOTPROTO=none
MASTER=bond1
SLAVE=yes
USERCTL=no

If i'm configuring multiple channel bonding incorrectly, please advise.

Version-Release number of selected component (if applicable):
RHEL5
initscripts-8.45.14.EL-1

How reproducible:
Every reboot or interface initialization

Steps to Reproduce:
1. Copy above config
2. boot up server or do shell>ifup bond0; ifup bond1

  
Actual results:
the bond that is initialized first will work, the second one will not. The
bonding driver will only create a bonding interface if the device is present in
/sys/class/net/bonding_masters. The ifup-eth script will only add a single
device to /sys/class/net/bonding_masters. 

Expected results:
both bond0 and bond1 initialized

Additional info:
The workaround is to apply this patch to
/etc/sysconfig/network-scripts/network-functions
