Subject: [dpdk-users] Use custom rss hash field for gtp-u detunneling
Date: Thu, 10 Oct 2019 09:45:08 +0900	[thread overview]
Message-ID: <CAJzQz-G53YaSoOqhcyyNnBM3WApi66C+8Jvkb-ACSpa=2NO9Fw@mail.gmail.com> (raw)

I'm implementing gtp-u detunneling software.
  1. input traffic is 40g, so distribute with RSS into 4/8 cores.
  2. some input is ip-fragmented, so use ip_reassembly lib.
  3. gtp-u header deletion is straightforward.

Problem is distribution : outer-ip is not varied, and udp port is all 2152.
I think instead of 5-tuple, src_ip/dst_ip/IP_IDENTIFICATION would do the job.
because ip_identification is well distributed, and is same for all
fragmented ip packet.

Is it possible wth dpdk and x710 or x722 or any other nic?
