I think that's just a confusing error message. The real cause of the problem is 
that in the kernel used to test OFED 1.5.4.1, netif_set_real_num_tx_queues 
used to be a void function, but since receive/xmit packet steering was 
implemented, this function has turned into an int function.

Since the OFED code expects a void function, it's not going to do anything with 
the return value, so I think it's fair to say that changing the header to make 
it 
consistent with the kernel (and the implementation of the function) is going 
to do little harm, so I'd simply change the OFED header's "void" to "int" for 
the return type of the function.
