Support of Whitelist Features by Poll Mode Drivers
==================================================
Support igb_uio and vfio driver, if used vfio, kernel need 3.6+ and enable vt-d in bios.
When used vfio , used "modprobe vfio" and "modprobe vfio-pci" insmod vfiod driver, then used
"./tools/dpdk_nic_bind.py --bind=vfio-pci device_bus_id" to bind vfio driver to test driver.
The support of Whitelist offload features by Poll Mode Drivers consists in:
Prerequisites
=============
Assuming that at least a port is connected to a traffic generator,
launch the ``testpmd`` with the following arguments::
./x86_64-default-linuxapp-gcc/build/app/test-pmd/testpmd -c 0xc3 -n 3 -- -i \
--burst=1 --rxpt=0 --rxht=0 --rxwt=0 --txpt=36 --txht=0 --txwt=0 \
--txfreet=32 --rxfreet=64 --mbcache=250 --portmask=0x3
The -n command is used to select the number of memory channels. It should match the number of memory channels on that setup.
Set the verbose level to 1 to display informations for each received packet::
testpmd> set verbose 1
Show port infos for port 0 and store the default MAC address and the maximum
number of MAC addresses::
testpmd> show port info 0
********************* Infos for port 0 *********************
MAC address: 00:1B:21:4D:D2:24
Link status: up
Link speed: 10000 Mbps
Link duplex: full-duplex
Promiscuous mode: enabled
Allmulticast mode: disabled
Maximum number of MAC addresses: 127
Test Case: add/remove mac addresses
===================================
Initialise first port without ``promiscuous mode``::
testpmd> set promisc 0 off
Read the stats for port 0 before sending the packet::
testpmd> show port stats 8
######################## NIC statistics for port 8 ########################
RX-packets: 0 RX-errors: 0 RX-bytes: 64
TX-packets: 0 TX-errors: 0 TX-bytes: 0
############################################################################
Send a packet with default destination MAC address for port 0::
testpmd> show port stats 0
######################## NIC statistics for port 8 ########################
RX-packets: 1 RX-errors: 0 RX-bytes: 128
TX-packets: 0 TX-errors: 0 TX-bytes: 0
############################################################################
Verify that the packet was received (RX-packets incremented).
Send a packet with destination MAC address different than the port 0 address,
let's call it A.::
testpmd> show port stats 0
######################## NIC statistics for port 8 ########################
RX-packets: 1 RX-errors: 0 RX-bytes: 128
TX-packets: 0 TX-errors: 0 TX-bytes: 0
############################################################################
Verify that the packet was not received (RX-packets not incremented).
Add the MAC address A to the port 0::
testpmd> mac_addr add 0
testpmd> show port stats 0
######################## NIC statistics for port 8 ########################
RX-packets: 2 RX-errors: 0 RX-bytes: 192
TX-packets: 0 TX-errors: 0 TX-bytes: 0
############################################################################
Verify that the packet was received (RX-packets incremented).
Remove the MAC address A to the port 0::
testpmd> mac_addr remove 0
testpmd> show port stats 0
######################## NIC statistics for port 8 ########################
RX-packets: 2 RX-errors: 0 RX-bytes: 192
TX-packets: 0 TX-errors: 0 TX-bytes: 0
############################################################################
Verify that the packet was not received (RX-packets not incremented).
Test Case: invalid addresses test
=================================
Add a MAC address of all zeroes to the port 0::
testpmd> mac_addr add 0 00:00:00:00:00:00
Verify that the response is "Invalid argument" (-EINVAL)
Remove the default MAC address::
testpmd> mac_addr remove 0
Verify that the response is "Address already in use" (-EADDRINUSE)
Add two times the same address::
testpmd> mac_addr add 0
testpmd> mac_addr add 0
Verify that there is no error
Add as many different addresses as maximum MAC addresses (n)::
testpmd> mac_addr add 0
... n-times
testpmd> mac_addr add 0
Add one more different address::
testpmd> mac_addr add 0
Verify that the response is "No space left on device" (-ENOSPC)
