The goal of this\ntest suite is to align with the existing dts test plan for scattered\npackets within DTS.\n\nSigned-off-by: Jeremy Spewock <jspewock@iol.unh.edu>\n---\n dts/tests/TestSuite_pmd_buffer_scatter.py | 105 ++++++++++++++++++++++\n 1 file changed, 105 insertions(+)\n create mode 100644 dts/tests/TestSuite_pmd_buffer_scatter.py", "diff": "diff --git a/dts/tests/TestSuite_pmd_buffer_scatter.py b/dts/tests/TestSuite_pmd_buffer_scatter.py\nnew file mode 100644\nindex 0000000000..8e2a32a1aa\n--- /dev/null\n+++ b/dts/tests/TestSuite_pmd_buffer_scatter.py\n@@ -0,0 +1,105 @@\n+# SPDX-License-Identifier: BSD-3-Clause\n+# Copyright(c) 2023 University of New Hampshire\n+\n+\"\"\"Multi-segment packet scattering testing suite.\n+\n+Configure the Rx queues to have mbuf data buffers whose sizes are smaller than the maximum packet\n+size (currently set to 2048 to fit a full 1512-byte ethernet frame) and send a total of 5 packets\n+with lengths less than, equal to, and greater than the mbuf size (CRC included).\n+\"\"\"\n+import struct\n+\n+from scapy.layers.inet import IP # type: ignore[import]\n+from scapy.layers.l2 import Ether # type: ignore[import]\n+from scapy.packet import Raw # type: ignore[import]\n+from scapy.utils import hexstr # type: ignore[import]\n+\n+from framework.remote_session.remote.testpmd_shell import (\n+ TestPmdForwardingModes,\n+ TestPmdShell,\n+)\n+from framework.test_suite import TestSuite\n+\n+\n+class PmdBufferScatter(TestSuite):\n+ \"\"\"DPDK packet scattering test suite.\n+\n+ Attributes:\n+ mbsize: The size to se the mbuf to be.\n+ \"\"\"\n+\n+ mbsize: int\n+\n+ def set_up_suite(self) -> None:\n+ self.verify(\n+ len(self._port_links) > 1,\n+ \"Must have at least two port links to run scatter\",\n+ )\n+\n+ self.tg_node.main_session.configure_port_mtu(9000, self._tg_port_egress)\n+ self.tg_node.main_session.configure_port_mtu(9000, self._tg_port_ingress)\n+\n+ def scatter_pktgen_send_packet(self, pktsize: int) -> str:\n+ \"\"\"Generate and send packet to the SUT.\n+\n+ Functional test for scatter packets.\n+\n+ Args:\n+ pktsize: Size of the packet to generate and send.\n+ \"\"\"\n+ packet = Ether() / IP() / Raw()\n+ packet.getlayer(2).load = \"\"\n+ payload_len = pktsize - len(packet) - 4\n+ payload = [\"58\"] * payload_len\n+ # pack the payload\n+ for X_in_hex in payload:\n+ packet.load += struct.pack(\"=B\", int(\"%s%s\" % (X_in_hex[0], X_in_hex[1]), 16))\n+ load = hexstr(packet.getlayer(2), onlyhex=1)\n+ received_packets = self.send_packet_and_capture(packet)\n+ self.verify(len(received_packets) > 0, \"Did not receive any packets.\")\n+ load = hexstr(received_packets[0].getlayer(2), onlyhex=1)\n+\n+ return load\n+\n+ def pmd_scatter(self) -> None:\n+ \"\"\"Testpmd support of receiving and sending scattered multi-segment packets.\n+\n+ Support for scattered packets is shown by sending 5 packets of differing length\n+ where the length of the packet is calculated by taking mbuf-size + an offset.
