Summary: Node discovery fails with Broadcom Ethernet adapter

Initial Comment:
The ramdisk images (i.e. nbfs.x86 and nbfs.x86_64) supplied with xCAT 2.3 causes Node Discovery to fail when target node (x336 in this case) has Broadcom Ethernet adapters. The reason is the kernel module for Broadcom adapters (i.e. tg3.ko) has a dependancy for module libphy.ko that is not included in the ramdisk image.
Proof: Output from console (with "quiet" flag removed) is show below:

Found (tg3) Broadcom Corporationtg3: Unknown symbol phy_ethtool_sset
 NetXtreme BCM57tg3: Unknown symbol phy_mii_ioctl
21 Gigabit Ethertg3: Unknown symbol phy_connect
net PCI Express tg3: Unknown symbol mdiobus_register
(rev 11)
tg3: Unknown symbol phy_start
tg3: Unknown symbol phy_start_aneg
tg3: Unknown symbol mdiobus_unregister
tg3: Unknown symbol phy_ethtool_gset
tg3: Unknown symbol phy_stop
tg3: Unknown symbol phy_disconnect
insmod: cannot insert '/lib/modules/2.6.18-128.el5/kernel/drivers/net/tg3.ko': Unknown symbol in module (-1): No such file or directory
modprobe: failed to load module tg3
ifconfig: SIOCGIFFLAGS: No such device
udhcpc: SIOCGIFINDEX failed: No such device

Output from /var/log/messages i.e. Node discovery hangs at this point:
