 Step 1: Select the DPDK environment to build
----------------------------------------------------------
[1] i686-native-linuxapp-gcc
[2] i686-native-linuxapp-icc
[3] x86_64-ivshmem-linuxapp-gcc
[4] x86_64-ivshmem-linuxapp-icc
[5] x86_64-native-bsdapp-gcc
[6] x86_64-native-linuxapp-gcc
[7] x86_64-native-linuxapp-icc

----------------------------------------------------------
 Step 2: Setup linuxapp environment
----------------------------------------------------------
[8] Insert IGB UIO module
[9] Insert VFIO module
[10] Insert KNI module
[11] Setup hugepage mappings for non-NUMA systems
[12] Setup hugepage mappings for NUMA systems
[13] Display current Ethernet device settings
[14] Bind Ethernet device to IGB UIO module
[15] Bind Ethernet device to VFIO module
[16] Setup VFIO permissions

----------------------------------------------------------
 Step 3: Run test application for linuxapp environment
----------------------------------------------------------
[17] Run test application ($RTE_TARGET/app/test)
[18] Run testpmd application in interactive mode ($RTE_TARGET/app/testpmd)

----------------------------------------------------------
 Step 4: Other tools
----------------------------------------------------------
[19] List hugepage info from /proc/meminfo

----------------------------------------------------------
 Step 5: Uninstall and system cleanup
----------------------------------------------------------
[20] Uninstall all targets
[21] Unbind NICs from IGB UIO driver
[22] Remove IGB UIO module
[23] Remove VFIO module
[24] Remove KNI module
[25] Remove hugepage mappings

[26] Exit Script

Option: 12

Removing currently reserved hugepages
Unmounting /mnt/huge and removing directory

  Input the number of 2MB pages for each node
  Example: to have 128MB of hugepages available per node,
  enter '64' to reserve 64 * 2MB pages on each node
Number of pages for node0: 64
