I think you should not use prefix `spp` without if it defines a 
behaviour of SPP itself. This function is more essential to attach device.

For `spp_eth_dev_attach`, You might think similar name from original 
`rte_eth_dev_attach`, but I think we do not keep the name of deprecated 
APIs. More simply, how about `dev_attach_by_devargs` instead of?

For `spp_eth_dev_detach`, I think `dev_detach_by_port_id` is more 
prefer. Other than the name of the function, I am curious why it takes 
second argument `name` because it is not used in the function.

By the way, I am not clear what is the difference between your functions 
and `rte_eth_dev_attach` defined in 
`dpdk/lib/librte_ethdev/rte_ethdev.c` exactly. Could you explain about 
the difference shortly for helping my understanding?

Thanks
