Hello,
I am having an issue getting the DCB feature to work with an Intel
X710 Quad SFP+ NIC.
Here’s my setup:
1. DPDK 18.08 built with the following I40E configs:
CONFIG_RTE_LIBRTE_I40E_PMD=y
CONFIG_RTE_LIBRTE_I40E_DEBUG_RX=n
CONFIG_RTE_LIBRTE_I40E_DEBUG_TX=n
CONFIG_RTE_LIBRTE_I40E_DEBUG_TX_FREE=n
CONFIG_RTE_LIBRTE_I40E_RX_ALLOW_BULK_ALLOC=y
CONFIG_RTE_LIBRTE_I40E_INC_VECTOR=y
CONFIG_RTE_LIBRTE_I40E_16BYTE_RX_DESC=n
CONFIG_RTE_LIBRTE_I40E_QUEUE_NUM_PER_PF=64
CONFIG_RTE_LIBRTE_I40E_QUEUE_NUM_PER_VM=8
2. /opt/dpdk-18.08/usertools/dpdk-devbind.py --status-dev net

3. We have a custom FPGA board connected to port 1 of the X710 NIC that’s
broadcasting
a packet tagged with VLAN 1 and PCP 2.
4. I use the vmdq_dcb example app and configure the card with 16 pools/8
queue each
as follows:
sudo ./vmdq_dcb_app -l 1 -- -p3 --nb-pools 16 --nb-tcs 8 -p 3
The apps starts up fine and successfully probes the card as shown below:
sudo ./vmdq_dcb_app -l 1 -- -p3 --nb-pools 16 --nb-tcs 8 -p 3

However, when I issue the SIGHUP I see that the packets
are being put into the first queue of Pool 1 as follows:
Pool 0: 0 0 0 0 0 0 0 0

Finished handling signal 1
Since the packets are being tagged with PCP 2 they should be getting
mapped to 3rd queue of Pool 1, right?
As a sanity check, I tried the same test using an 82599ES 2 port 10GB NIC and
the packets show up in the expected queue. (Note, to get it to work I had
to modify the vmdq_dcb app to set the vmdq pool MACs to all FF’s)
Here’s that setup:
