283. Flexible RXd Test Suites¶
283.1. Description¶
The test suite will cover the flexible RX descriptor on Intel E810 network interface card.
283.2. Prerequisites¶
Copy correct ice.pkg into /lib/firmware/updates/intel/ice/ddp/, For the test cases, comms package is expected.
Prepare test toplogoy, in the test case, it requires
- 1 Intel E810 interface
- 1 network interface for sending test packet, which could be connect to the E810 interface
- Directly connect the 2 interfaces
Patch testpmd for dumping flexible fields from RXD:

Bind Intel E810 interface to igb_uio driver, (e.g. 0000:18:00.0)
./usertools/dpdk-devbind.py -b igb_uio 18:00.0
283.3. Test Case 01: Check single VLAN fields in RXD (802.1Q)¶
Launch testpmd by:
./x86_64-native-linux-gcc/app/dpdk-testpmd -l 6-9 -n 4 -a 18:00.0,proto_xtr=vlan -- -i --rxq=32 --txq=32 --portmask=0x1 --nb-cores=2
testpmd>set verbose 1
testpmd>set fwd io
testpmd>start
Please change the core setting (-l option) and port’s PCI (-a option) by your DUT environment
Send a packet with VLAN tag from test network interface:
scapy #launch scapy in shell
#In scapy interactive UI
p = Ether(src="3c:fd:fe:c0:e1:8c", dst="00:00:00:00:01:02", type=0x8100)/Dot1Q(prio=1,vlan=23)/IP()/UDP()/DNS()
sendp(p, iface='enp175s0f0', count=1)
Please notice
- Change ethernet source address with your test network interface’s address
- Make sure the ethernet destination address is NOT your real E810 interface’s address
Check the output in testpmd, ctag=1:0:23 is expected, which is consistent with VLAN tag set in test packet:

283.13. Test Case 11: Check effect of replacing pkg from RXID #22 to RXID #16¶
Put the ice.pkg with RXID #16(ice-1.3.7.0.pkg and more) to /lib/firmware/updates/intel/ice/ddp/ice.pkg, then reload ice driver:
rmmod ice
modprobe ice
Make sure the new ice.pkg is different with the original one. Take ‘dmesg’ command to get ice.pkg version:
dmesg | grep package
Start the testpmd:
./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -c 0xff -n 4 -- -i --rxq=64 --txq=64
Check the testpmd started failed. Failed info output:
Port (0) - Rx queue (0) is set with RXDID : 16

ice_dev_start(): fail to start Rx queue 0
Fail to start port 0
Please stop the ports first
Port (0) - Rx queue (0) is set with RXDID : 16
Replace correct ice.pkg to /lib/firmware/updates/intel/ice/ddp/ice.pkg,then reload ice driver:
rmmod ice
modprobe ice.ko
