-ICE 1PPS Signal Test Plan
-=========================
-
-Description
-===========
-The Intel® Ethernet 800 Series supports a total of four single-ended GPIO signals(SPD[20:23])plus
-one different GPIO signal (CLK_OUT_P/N), which is configured by default 1PPS(out). The SPD[20:23]
-is mapping to pin_id[0:3]. This test plan is designed to check the value of related registers,
-which make up the 1PPS signal. The registers address depends on some hardware config.
-The test cases only give the example of E810-XXVDA4 and E810-CQ.
-
-
-Prerequisites
-=============
-
-Topology
---------
-DUT port 0 <----> Tester port 0
-
-Hardware
---------
-Supported NICs: Intel® Ethernet 800 Series E810-XXVDA4/E810-CQ
-
-Software
---------
-dpdk: http://dpdk.org/git/dpdk
-scapy: http://www.secdev.org/projects/scapy/
-
-General set up
---------------
-1. Compile DPDK::
-
-    # CC=gcc meson --werror -Denable_kmods=True -Dlibdir=lib --default-library=static <dpdk build dir>
-    # ninja -C <dpdk build dir> -j 110
-
-2. Get the pci device id and interface of DUT and tester.
-   For example, 0000:18:00.0 and 0000:18:00.1 is pci device id,
-   ens785f0 and ens785f1 is interface::
-
-    <dpdk dir># ./usertools/dpdk-devbind.py -s
-
-    0000:18:00.0 'Device 159b' if=ens785f0 drv=ice unused=vfio-pci
-    0000:18:00.1 'Device 159b' if=ens785f1 drv=ice unused=vfio-pci
-
-3. Bind the DUT port to dpdk::
-
-    <dpdk dir># ./usertools/dpdk-devbind.py -b vfio-pci <DUT port pci device id>
-
-
