Subject: Rss hash on mellanox 100G card
Date: Sun, 9 Jan 2022 12:20:37 +0000	[thread overview]
Message-ID: <AM9PR09MB4995C12F3B37F0357CF12E57A14F9@AM9PR09MB4995.eurprd09.prod.outlook.com> (raw)

I am using Mellanox Technologies MT27800 Family [ConnectX-5], using dpdk 19 with multi rx queue with rss port_conf.rx_adv_conf.rss_conf.rss_hf=(ETH_RSS_IP | ETH_RSS_UDP | ETH_RSS_TCP)

I analyze traffic and need all packet of same session to arrive to the same process ( session for now can be ip+port)

So Packet that have the same ip + port arrive to the same queue.

But If some packet are ip fragmented, packet arrive to different process. It is a problem!

How can i calculate the hash value in the c++ code, like it is done in the card, so i can reassemble packets and send them to the same process like the non fragmented packets?
