Thanks for the reply
The options in each of the physical interfaces seemed to be ok the
settings post 'service network restart' were:

Does your system have Broadcom NICs vs Intel / other?
Is their a way to query the tg3 module to see if those parameters being
passed are valid? Their was no output into /var/log/messages to reflect
any error on the parameters:

Put something similar to this in your
/etc/sysconfig/network-scripts/ifcfg-eth? file(s)
