ixv -- Intel 10 Gigabit Ethernet virtual function
ixv* at pci? dev ? function ?
The ixv driver supports Intel 10 Gigabit Ethernet virtual function that 82599 and newer chips support. It can be used on a NetBSD guest that the host supports SR-IOV.
The ixv driver doesn't use the common MCLGET(9) interface and use the driver specific cluster allocation mechanism. If it's exhausted, the evcnt(9) counter "ixgX qY Rx no jumbo mbuf" is incremented. If this is observed, the number can be changed by the following config parameter: IXGBE_JCLNUM_MULTI The number of RX jumbo buffers (clusters) per queue is calculated by IXGBE_JCLNUM_MULTI * (num- ber of rx descriptors). The total number of clus- ters per queue is available with the hw.ixgN.num_jcl_per_queue sysctl(7).
