+ICE DCF DISABLE ACL engine
+==========================
+
+Description
+===========
+
+Support disabling DCF ACL engine via `devarg` "acl=off" in cmdline, aiming to shorten the DCF startup time.
+After disabling the ACL engine, some of the rules supported by the ACL engine will be created by the Switch engine and others will failed to be created,
+as shown in the following table.

+
+    dut_port_1 <---> tester_port_1
+
+Hardware
+--------
+
+    Supportted NICs: columbiaville_25g/columbiaville_100g
+
+Software
+--------
+
+    dpdk: http://dpdk.org/git/dpdk
+
+    scapy: http://www.secdev.org/projects/scapy/
+
+General set up
+--------------
+
+1. Compile DPDK::
+
+    CC=gcc meson -Denable_kmods=True -Dlibdir=lib  --default-library=static x86_64-native-linuxapp-gcc
+    ninja -C x86_64-native-linuxapp-gcc
+
+2. Get the pci device id of DUT, for example::
+
+    ./usertools/dpdk-devbind.py -s
+
+    0000:17:00.0 'Ethernet Controller E810-C for QSFP 1592' if=ens9 drv=ice unused=vfio-pci
+
+3. Generate 2 VFs on PF0::
+
+    echo 2 > /sys/bus/pci/devices/0000:17:00.0/sriov_numvfs
+
+    ./usertools/dpdk-devbind.py -s
+    0000:17:01.0 'Ethernet Adaptive Virtual Function 1889' drv=vfio-pci unused=iavf
+    0000:17:01.1 'Ethernet Adaptive Virtual Function 1889' drv=vfio-pci unused=iavf
+
+4. Set VF0 as trust and set VF1 mac adress::
+
+    ip link set ens9 vf 0 trust on
+    ip link set enp9 vf 1 mac 00:01:23:45:67:89
+
+5. Bind VFs to dpdk driver::
+
+    modprobe vfio-pci
+    ./usertools/dpdk-devbind.py -b vfio-pci 0000:17:01.0 0000:17:01.1
+
+6. Start testpmd on VF0, VF0 request DCF mode and add parameter "acl=off" to disable the ACL engine::
+
+    ./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -c 0xf -n 4 -a 0000:17:01.0,cap=dcf,acl=off --file-prefix=vf0 --log-level="ice,7" -- -i
+
+    Check that when starting testpmd, the application prints "ice_flow_init():Engine 4 disabled"
+
+    Quit testpmd::
+
+    testpmd> quit
+
+    Check that when quitting testpmd, the application prints "ice_flow_uninit():Engine 4 disabled skip it"
+
+Test Case
+=========
+
+Test Case 1:  Compare start-up time
+-----------------------------------
+
+It takes too much time to enable the ACL engine when starting testpmd, so the startup time should be shortened after disabling ACL.
+
+test steps
+~~~~~~~~~~
+
+1. Disable ACL, execute command and record the time "start_time_disable_acl"::
+
+    echo quit | time ./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -c 0xf -n 4 -a 0000:17:01.0,cap=dcf,acl=off --file-prefix=vf0 --log-level="ice,7" -- -i
+
+2. Enable ACL, execute command and record the time "start_time_enable_acl"::
+
+    echo quit | time ./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -c 0xf -n 4 -a 0000:17:01.0,cap=dcf --file-prefix=vf1 --log-level="ice,7" -- -i
+
+3. Repeat step 1~2 for at least 6 times to get the average time of "start_time_disable_acl" and "start_time_enable_acl".
+
+
+expected result
+~~~~~~~~~~~~~~~
+
+    Check that the average start-up time with "acl=off" is shorter than that without "acl=off".
+
+Test Case 2: disable ACL engine
+-------------------------------
+
+Add "--log-level='ice,7'" when launching testpmd, it will print the detailed information when creating one rule.
+"Succeeded to create (4) flow" means the rule was created by the ACL engine, "Succeeded to create (2) flow" means it was created by the Switch engine.
+Therefore, when creating ACL rules after disabling the ACL engine, the ACL engine will fail to create any of these rules,
+but some of them can be successfully created by the switch engine.
+
+test steps
+~~~~~~~~~~
+
+1. Start testpmd::
+
+    ./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -c 0xf -n 4 -a 0000:17:01.0,cap=dcf,acl=off -a 17:01.1 --file-prefix=vf0 --log-level="ice,7" -- -i
+
+2. Create ACL rules on port 0::
+
+    Switch supported rules::
+
+    ipv4:
+        flow create 0 ingress pattern eth dst spec 00:11:22:33:44:55 dst mask ff:ff:ff:ff:ff:ff / ipv4 / end actions drop / end
