Though LRO support has been removed and GRO added, the module parameter
lro_disable is still available (though using it does nothing other than
print an error message indicating that the module option is deprecated).
This will allow the module to still load for users who are updating to
the newer kernel and still have the option configured in
/etc/modprobe.conf or other locations.
The driver update has been verified by Cisco. I tested both the driver
update and module option change and found no issues either.
This will resolve RHBZ 568111.
