Hi,


I have an X722 adapter using the i40e driver deployed with DPDK 17.11.4 on Red Hat 7.5 Linux system.



System is set up to bond two interfaces and then two VLANs on the bond for client and server traffic.



This works with DPDK 17.11.4 except that failover of interfaces within the bond does not work correctly. Change of status on an interface is not detected.



Driver version is 2.9.21 and firmware 4.00 0x8000183f 1.1937.0


# ethtool -i eno2

driver: i40e

version: 2.9.21

firmware-version: 4.00 0x8000183f 1.1937.0

expansion-rom-version:

bus-info: 0000:09:00.1

supports-statistics: yes

supports-test: yes

supports-eeprom-access: yes

supports-register-dump: yes

supports-priv-flags: yes



# lspci | grep -i ether

09:00.0 Ethernet controller: Intel Corporation Ethernet Connection X722 for 10GbE backplane (rev 09)

09:00.1 Ethernet controller: Intel Corporation Ethernet Connection X722 for 10GbE backplane (rev 09)

09:00.2 Ethernet controller: Intel Corporation Ethernet Connection X722 for 10GbE backplane (rev 09)

09:00.3 Ethernet controller: Intel Corporation Ethernet Connection X722 for 10GbE backplane (rev 09)

Is there any reason why failover would not work in this case within DPDK?

Thanks
