4 years agoapp/testpmd: fix RSS key for flow API RSS rule
Lijun Ou [Wed, 21 Oct 2020 10:07:10 +0000 (18:07 +0800)]
app/testpmd: fix RSS key for flow API RSS rule

When a flow API RSS rule is issued in testpmd, device RSS key is changed
unexpectedly, device RSS key is changed to the testpmd default RSS key.

Consider the following usage with testpmd:
1. first, startup testpmd:
 testpmd> show port 0 rss-hash key
 RSS functions: all ipv4-frag ipv4-other ipv6-frag ipv6-other ip
 RSS key: 6D5A56DA255B0EC24167253D43A38FB0D0CA2BCBAE7B30B477CB2DA38030F
          20C6A42B73BBEAC01FA
2. create a rss rule
 testpmd> flow create 0 ingress pattern eth / ipv4 / udp / end \
          actions rss types ipv4-udp end queues end / end

3. show rss-hash key
 testpmd> show port 0 rss-hash key
 RSS functions: all ipv4-udp udp
 RSS key: 74657374706D6427732064656661756C74205253532068617368206B65792
          C206F76657272696465

This is because testpmd always sends a key with the RSS rule,
if user provides a key as part of the rule that key is used, if user
doesn't provide a key, testpmd default key is sent to the PMDs, which is
causing device programmed RSS key to be changed.

There was a previous attempt to fix the same issue [1], but it has been
reverted back [2] because of the crash when 'key_len' is provided
without 'key'.

This patch follows the same approach with the initial fix [1] but also
addresses the crash.

After change, testpmd RSS key is 'NULL' by default, if user provides a
key as part of rule it is used, if not no key is sent to the PMDs at all

MPRQ (Multi-Packet Rx Queue) processes one packet at a time using
simple scalar instructions. MPRQ works by posting a single large buffer
(consisted of multiple fixed-size strides) in order to receive multiple
packets at once on this buffer. A Rx packet is then copied to a
user-provided mbuf or PMD attaches the Rx packet to the mbuf by the
pointer to an external buffer.

There is an opportunity to speed up the packet receiving by processing
4 packets simultaneously using SIMD (single instruction, multiple data)
extensions. Allocate mbufs in batches for every MPRQ buffer and process
the packets in groups of 4 until all the strides are exhausted. Then
switch to another MPRQ buffer and repeat the process over again.

The vectorized MPRQ burst routine is engaged automatically in case
the mprq_en=1 devarg is specified and the vectorization is not disabled
