Bug ID: 352
Summary: Bifurcated Driver X710 for ipv6 flow rule addition not
working
Product: DPDK
Version: unspecified
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: major
Priority: Normal
Component: examples
Assignee: dev@dpdk.org
Reporter: muthurajan.jayaku...@intel.com
Target Milestone: ---
We received X710 cards and were able to obtain connectivity! Thank you!
We were trying to setup flow bifurcation on the card for DPDK
(https://doc.dpdk.org/guides/howto/flow_bifurcation.html#using-flow-bifurcation-on-i40e-in-linux),
but it seems I cannot get an ip6 or tcp6 flow rule to be accepted via the i40e
driver. I keep getting “Cannot insert RX class rule: Invalid argument”

The README of i40e driver (version 2.9.21) still says that “NOTE: The Linux
i40e driver supports the following flow types: IPv4, TCPv4, and UDPv4.”
Would the XL710 card support IPv6 (TCPv6) flow types via some other mechanism?
