2018-01-24linux-generic: pktio: add null pktio supportJuha-Matti Tilli
Sometimes, you may wish to run an application by using a dummy interface that never receives any packets and that discards transmitted packets. This is possible with non-looping pcap pktio with no input and output pcaps. So, the pktio would be just "pcap:". However, you cannot have two pktios named "pcap:" because there is code to check if the pktio is already opened. Also, the pcap pktio requires that ODP is compiled with the pcap library, which it may not be. Also, pcap is always single-queue and therefore not suitable for modern multi-queue applications. Also, recently a patch was provided to ODP to allow interruptible sleep when receiving packets. This, however, does not work with mixed pcap and socket/netmap pktio types. To fix these issues, a new "null" pktio is introduced. It is used by specifying the interface name to be "null:0", "null:1", or similar. All packets sent to the null pktio are discarded and no packets are received. The null pktio fully supports the interruptible sleep infrastructure, meaning applications can have 0% idle CPU load when one interface is a null interface and another interface is socket or netmap.

2018-01-17linux-generic: pktio: genuinely sleep in timeout receiveJuha-Matti Tilli
ODP has two functions, odp_pktin_recv_tmo and odp_pktin_recv_mq_tmo that allow sleeping for a certain time. However, the sleep was not a genuine interruptible sleep (select/poll/epoll) but rather a busy loop. This resulted in high CPU use when this call was used. This functionality adds to three pktio mechanisms a way to allow sleeping using select() system call. The way is used if all used pktio mechanisms support it.
