Change Details

Add support for those cases where only a subset of the TX rings are opened, and where RX rings are not opened. Rather than checking `IFCAP_NETMAP`, rely on the `netmap_kring_on()` helper, and on the return value of `netmap_tx_irq()`. In the interrupt handler, in particular, there is no need to call `isc_credits_update`.
