 -------------
 
-This section demonstrates how to launch **testpmd** with Amazon ENA
-devices managed by librte_pmd_ena.
-
-#. Load the kernel modules:
-
-   .. code-block:: console
-
-      modprobe uio
-      insmod ./x86_64-native-linuxapp-gcc/kmod/igb_uio.ko
-
-   .. note::
-
-      Currently Amazon ENA PMD driver depends on igb_uio user space I/O kernel module
-
-#. Mount and request huge pages:
-
-   .. code-block:: console
-
-      mount -t hugetlbfs nodev /mnt/hugepages
-      echo 1024 > /sys/kernel/mm/hugepages/hugepages-2048kB/nr_hugepages
-
-#. Bind UIO driver to ENA device (using provided by DPDK binding tool):
-
-   .. code-block:: console
-
-      ./usertools/dpdk-devbind.py --bind=igb_uio 0000:02:00.1
-
-#. Start testpmd with basic parameters:
-
-   .. code-block:: console
-
-      ./x86_64-native-linuxapp-gcc/app/testpmd -l 0-3 -n 4 -- -i
-
-   Example output:
-
-   .. code-block:: console
-
