Hello,
Is there a way to filter packets which received by dpdk kernel or libpcap
according to ip mask and port ? I need to support fragmented ip packets and
fragmented tcp packets.
Can I use *Packet Classification* for this purpose*? *
Thank you, Keren

Hi,
The pcap PMD for DPDK is a SW only driver and does not support any
packet classification options in itself. If you can use a native HW
driver for your NIC it may be possible to have the hardware do packet
classification and filtering for you.
