Hi, I've been trying to test SR-IOV on -CURRENT and 11.0-RELEASE. Physical NIC is an X552. The ixgbe PF has to be limited to 1-4 queues in order to create VFs or you will get ENOSPC from iovctl. Either letting ixv try to attach on the host, or creating a passthrough and allowing pfsense 2.4.0 beta to try to attach yields this failure to attach: m 0xc0104000-0xc0107fff,0xc0108000-0xc010bfff at device 7.0 on pci0 ixv0: Using MSIX interrupts with 2 vectors ixv0: ixgbe_reset_hw() failed with error -10 device_attach: ixv0 attach returned 5 Another issue, the PF is unable to pass traffic after creating a VF. 'iovctl -D -d ix0; service netif restart; service routing restart' will restore connectivity. Regards, Kevin
