Bug ID: 577
Summary: x540-AT2: Can Flow Director filter fragmented packet ?
Product: DPDK
Version: 17.05
Hardware: x86
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: Normal
Component: other
Assignee: dev@dpdk.org

Target Milestone: ---
Hi all,
I'm trying to use flow-director to split data traffic to a VF in NIC X540-AT2
and I have successfully experimented this solution with packet ( MTU < 1500 ) .
But with packet that bigger than MTU 1500 ( IP fragmentation breaks packets
into smaller fragments ) , Flow Director doesn't work !!!!!
- As a guide:
https://doc.dpdk.org/guides-17.05/howto/flow_bifurcation.html
- Create VFs :
#echo 1 > /sys/class/net/p7p2/device/sriov_numvfs
- Config Flow Director ( for queue_id 0 of VF 1 ) :
#ethool --config-ntuple p7p2 flow-type udp4 dst-ip 192.168.1.5 dst-port 2152
action 4294967296 (action = vf_id * 2^32 + queue_id ) .
Can i ask a question : Can Flow Director filter fragmented packet ?
Brgs,
