Can't install tg3-driver for Broadcom NIC

[Guest]

Sorry, but i need support installing a Broadcom NIC.
I've downloaded the newest driver at
www broadcom.com/support/ethernet_nic/netxtreme_desktop.php

Endian V2.3 Community (fresh installed)
lspci says "...Broadcom Corporation Unknown device 1690 (rev 01)"
Now i have a tg3-3.110g-1.src.rpm in my /tmp folder.
I extract the files to
/usr/src/endian/SOURCES
/usr/src/endian/SPECS
with
rpm -ivh tg3-3.110g-1.src.rpm

Now when i try to

rpm -bb tg3-spec

I get "Unknown Option -bb"
Which options do i need?

I don't know what to do now. I will be lucky about help.
