Is it possible for two processes to share the same mbuf_pool in SR-IOV with single rx/tx queue?
rte_pktmbuf_pool_create(mbuf_pool_name, NB_MBUFS,
MBUF_CACHE_SIZE, 0, RTE_MBUF_DEFAULT_BUF_SIZE,
rte_socket_id());
We have seen that it does not work. However, with PCI passthrough of whole NIC, we can easily share same mbuf_pool with many processes.
What are the limitations with SR-IOV?
The device is question is as follows:
06:00.0 Ethernet controller: Intel Corporation 82599ES 10-Gigabit SFI/SFP+ Network Connection (rev 01)
06:00.1 Ethernet controller: Intel Corporation 82599ES 10-Gigabit SFI/SFP+ Network Connection (rev 01)
06:10.0 Ethernet controller: Intel Corporation 82599 Ethernet Controller Virtual Function (rev 01)
06:10.1 Ethernet controller: Intel Corporation 82599 Ethernet Controller Virtual Function (rev 01)
06:10.2 Ethernet controller: Intel Corporation 82599 Ethernet Controller Virtual Function (rev 01)
06:10.3 Ethernet controller: Intel Corporation 82599 Ethernet Controller Virtual Function (rev 01)
