Dave Jiang a792f1de88 ntb: Fix calculation ntb_transport_tx_free_entry() ... commit 5a7693e6bb upstream. ntb_transport_tx_free_entry() never returns 0 with the current calculation. If head == tail, then it would return qp->tx_max_entry. Change compare to tail >= head and when they are equal, a 0 would be returned.
