[dpdk-dev] PF vlan filter can not work in x710

2018-02-10 Thread ychen 
hi,
when I use X710 PF in dpdk mode, i found that vlan filter function does not 
work. when I only add vlan 102, but I can receive packets with  vlan 
tag100,200,300 etc.


I can reproduce this phenomenon following the step:
1. set iommu=pt intel_iommu=on in file /etc/default/grub
2. dpdk-devbind -b vfio-pci eth0
driver: i40e
version: 2.3.6
firmware-version: 5.04 0x8000250b 17.5.10
expansion-rom-version: 
bus-info: :05:00.0
supports-statistics: yes
supports-test: yes
supports-eeprom-access: yes
supports-register-dump: yes
supports-priv-flags: yes


3.use dpdk version 17.08 and ovs version 2.8.0
4.in ovs code, add vlan filter in function dpdk_eth_dev_init():
   a. set conf.rxmode.hw_vlan_filter =1 before use function 
rte_eth_dev_configure() 
   b. call function rte_eth_dev_vlan_filter(dev->port_id, 102,1)
   c. call function rte_eth_dev_start

[dpdk-dev] why all the other threads except lcore-slave pinned to master lcore?

Hi, I am a freshman learning DPDK, when I followed the document INSTALL.DPDK.md 
to launch openvswitch with dpdk inited, I found that all the threads are pinned 
to master lcore except lcore-slave and vfio-sync, but I can not find any code 
to set the affinity for these threads. 
Here is my question:
1. why vfio-sync is pinned to a core which is not included in the slave lcore 
nor master lcore?
2. why all other threads pinned to master lcore? is anything I am setting wrong?


Here is some logs:
