There are many issues on the lists.dell.com concerning the broadcom
cards. As an example:

http://lists.us.dell.com/pipermail/linux-poweredge/2004-October/thread.html#16951

I just checked all my dell servers (I have many) ... but most seem to have intel gigbit NICs.

"Intel Corporation 82541GI/PI Gigabit Ethernet Controller" on most.

Well ... I have this on one machine and it seems to be working OK:

"Broadcom Corporation NetXtreme BCM5721 Gigabit Ethernet PCI Express"

If you use these search terms on google, you will see many issues with broadcom cards on RHEL:
