Subject: [dpdk-dev] [RFC PATCH 0/2] using scapy to generate packet templates
Date: Thu, 19 Oct 2017 22:06:47 +0800 [thread overview]
Message-ID: <20171019140649.26668-1-xuemingl@mellanox.com> (raw)
The target is to make testpmd flexible to generate all kinds of packet
in just one line. Examples:
# send UDP packet to port 0 queue 0
testpmd> scapy 0 Ether()/IP()/UDP()/"hello_world"
# send 4 L3 VXLAN packets with inner UDP dport 1-4 to port 1 queue 1-4, one packet per queue
testpmd> scapy 1 Ether()/IP()/UDP()/VXLAN()/IPv6()/UDP(dport=(1,4))/"cool"
# Random
testpmd> scapy 2 Ether(src=RandMAC())/IP(dst=RandIP())/TCP(sport=RandShort(),dport=0x1234)
This patch introduce scapy - a python tool to generate static packet templates.
Txonly forwarding mode is modified to support template if available.
Two new configuration:
CONFIG_RTE_TEST_PMD_SCAPY=y
CONFIG_RTE_PYTHON=python2.7
Scapy quick demo: http://www.secdev.org/projects/scapy/demo.html
There are 2 other potential solution to support more fancy sending in the future:
1. Invoke scapy and expose mbuf hugepage pointers to python
This should allow more flexible and dynamic processing
2. Scapy uses wrapped DPDK port as regular port
Make scapy capable to send high speed streams.
