Hi Banu,

Not wishing to "muddy the waters" but I would like to point out that
the latest Broadcom Tigon3 driver upstream, in the Linux kernel
(kernel.org), is version 3.137

I am typing this reply from a RHEL-6 system that is using the ELRepo
Project's kernel-lt package. As the hardware requires the tg3 driver I
thought you might like to see the relevant output from an lshw -c
network command --

[code]
$ sudo lshw -c network

For good measure, here is the output from modinfo --
