Can you please describe the problem more.
Without this patch rx->fd == tx->fd, with this patch rx and tx has
different file descriptors.

What was the wrong with rx and tx having same fd?

As far as I can see, rte_eth_rx_queue_setup() won't close tx->fd, that
function will do nothing if rx or tx has valid fd.
