[dpdk-users] examples/ip_reassembly - lcore per port

[Saar Tarnopolsky <saart@mellanox.com>]

Hi,

I am using the dpdk ip_reassambly code to reassemble fragmented packets sent to my Mellanox ConnectX-5.
While running the code I noticed that I can only run with one lcore per port. After reviewing the ip_reassembly code I saw that the code is built to initialize only lcore per port.
Is this a bug in the code?
Is there any way to run the ip_reassembly with more than one lcore per port? Or do I need to make my own modifications to the code to be able to tun it this way?

I run this command: ./build/ip_reassembly -l 0-3 -w 03:00.0 -- -p 0x1

And I get the following messages:
