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 ?
