A bug about we use flag NR_REG_ONE_NIC in nm_open() #7

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
In file: netmap_user.h:
line: 511.

508        } else if (nr_flags == NR_REG_ONE_NIC) {
509     /* XXX check validity */
510     d->first_tx_ring = d->last_tx_ring =
511     d->first_rx_ring = d->last_rx_ring = nr_ringid;
512 } else { /* pipes */

If we use NETMAP_NO_TX_POLL or/and NETMAP_DO_RX_POLL on nr_ringid, there is an 
error.So, the ring way is:

508        } else if (nr_flags == NR_REG_ONE_NIC) {
509     /* XXX check validity */
510     d->first_tx_ring = d->last_tx_ring =
511     d->first_rx_ring = d->last_rx_ring = (nr_ringid & NETMAP_RING_MASK);
512 } else { /* pipes */

PS: I have sent an email to  rizzo##iet.unipi.it, but there is no any response 
to me. Please reply an email to me(dubingo201##hotmail.com). Thank you.
