Hi, I would like to implement a scenario like the following:
- Some NICs are bound to the igb_uio driver - A DPDK application is started and it sends/receives packet to/from those NICs. - Another set of NICs are bound to the igb_uio driver. - The same DPDK application continues processing packets from the old NICs and starts processing packets from the new NICs as well. I have done some tests and the DPDK application sees the new NICs after a call to rte_eal_pci_probe(). Though I'm having some question: - Can I call rte_eal_pci_probe() whenever I want? Will it interfere with existing NICs' operations? (the documentation doesn't say much about that) - Will it work with DPDK 1.7 and DPDK 1.8? I'm asking because I've noticed that in DPDK 1.7 rte_eal_pci_probe() checks if a NIC is already registered, while in DPDK 1.8 this check has been removed. I've seen that there's some work towards proper hotplug support, but I was hoping to get the above (just adding, no removals) working with current DPDK releases. Thanks, Daniele Di Proietto
