No issue for pushing this to next release, but not sure if this API change
effects end user.

"struct rte_eth_rxtx_callback" is private data structure, previously how user
should be using it can be:

a)
void *cb;
cb = rte_eth_add_rx_callback(..);
rte_eth_remove_rx_callback(.., cb);

b)
struct rte_eth_rxtx_callback *cb;
cb = rte_eth_add_rx_callback(..);
rte_eth_remove_rx_callback(.., cb);


And same a) or b) can be used without any side effect with updated API.
