Subject: [patch net-next RFC 0/6] Add support for offloading packet-sampling
Date: Wed, 12 Oct 2016 14:41:03 +0200 [thread overview]
Message-ID: <1476276069-5315-1-git-send-email-jiri@resnulli.us> (raw)
From: Jiri Pirko <jiri@mellanox.com>
Add the sample tc action, which allows to sample packet matching
a classifier. The sample action peeks randomly packets, duplicates them,
truncates them and adds informative metadata on the packet, for example,
the input interface and the original packet length. The sampled packets
are marked to allow matching them and redirecting them to a specific
collector device.
The sampled packets metadata is packed using ife encapsulation. To do
that, this patch-set extracts ife logics from the tc_ife action into an
independent ife module, and uses that functionality to pack the metadata.
To include all the needed metadata, this patch-set introduces some new
IFE_META tlv types.
In addition, Add the support for offloading the matchall-sample tc command
in the Mellanox mlxsw driver, for ingress qdiscs.
Yotam Gigi (6):
Introduce ife encapsulation module
act_ife: Change to use ife module
ife: Introduce new metadata tlv types
Introduce sample tc action
mlxsw: reg: add the Monitoring Packet Sampling Configuration Register
mlxsw: packet sample: Add packet sample offloading support
