Re: Strange setting helps - need to know why?
1. edit the modprobe.conf and replace bnx2 with tg3
2. ifdown eth2
3. lsmod |grep tg3 (to confirm if tg3 is loaded.
4. ifup eth2
5. ethtool -i eth2 (to verify if driver is loaded.
Thanks
Mike.

Re: Strange setting helps - need to know why?
After running "ifdown eth2", the bnx2 driver module remains loaded. To unload it, you should use "modprobe -r bnx2" or "rmmod bnx2". If other NICs on your system use the bnx2 driver, the module won't unload unless all of them have been shut down.
Likewise, since eth2 was already claimed by the bnx2 driver, if you have other NICs that use the tg3 driver, you may have to shutdown all those NICs and then unload & reload the tg3 driver to make it notice that eth2 is now available for it too.
The alias entries in the modprobe.conf file only decide which driver module the OS attempts to load for each NIC; when a driver module is loaded, it will look for unclaimed hardware that is recognized by the driver code. With PCI/PCI-X/PCIe hardware, this recognition is usually done using the PCI hardware identifiers, but the driver module may implement extra checks.
