VMWARE vmxnet3 device driver plugin
##Overview This plugin provides native PCI driver support for VMWare vmxnet3.
##Prerequisites
-
This code is tested with vfio-pci driver installed with Ubuntu 18.04 which has kernel version 4.15.0-33-generic.
-
This code is tested with ESXi vSwitch version 6.0, release build 3620759.
-
Driver requires MSI-X interrupt support, which is not supported by uio_pci_generic driver, so vfio-pci needs to be used. On systems without IOMMU vfio driver can still be used with recent kernels which support no-iommu mode.
##Known issues
- VLAN filter
Usage
System setup
- load VFIO driver
sudo modprobe vfio-pci
- (systems without IOMMU only) enable unsafe NOIOMMU mode
echo Y | sudo tee /sys/module/vfio/parameters/enable_unsafe_noiommu_mode
- Bind interface to vfio-pci
sudo dpdk-devbind.py --bind vfio-pci 0b:00.0
Interface Creation
Interface can be dynamically created with following CLI:
create interface vmxnet3 0000:0b:00.0
set int state vmxnet3-0/b/0/0 up
Interface Deletion
Interface can be deleted with following CLI:
delete interface vmxnet3 <if-name>
Interface Statistics
Interface statistics can be displayed with show hardware-interface <if-name>
command.
Show Interface CLI
Interface and ring information can be obtained with
show vmxnet3 [if-name] [desc]
