+Ability to use external memory test plan
+=========================================
+
+Description:
+------------
+Provide an abstraction for DPDK hugepage allocation, to have a "default" memory
+allocator that will allocate hugepages, but also have custom allocator support for
+external memory.
+
+Test case 1: IGB_UIO and anonymous memory allocation
+-----------------------------------------------------
+Bind the ports to IGB_UIO driver
+
+Start testpmd with --mp-alloc=xmem flag::
+
+ ./x86_64-native-linuxapp-gcc/app/testpmd -c 0xf -n 4 -- --mp-alloc=xmem -i
+
+Start forward in testpmd
+
+Start send traffic from outside to test the forward function
+
+
+Test case 2: IGB_UIO and anonymous hugepage memory allocation
+--------------------------------------------------------------
+
+Bind the ports to IGB_UIO driver
+
+Start testpmd with --mp-alloc=xmemhuge flag::
+
+ ./x86_64-native-linuxapp-gcc/app/testpmd -c 0xf -n 4 -- --mp-alloc=xmemhuge -i
+
+Start forward in testpmd
+
+Start send traffic from outside to test the forward function
+
+
+Test case 3: VFIO and anonymous memory allocation
+--------------------------------------------------
+Bind the ports to vfio-pci driver
+
+Start testpmd with --mp-alloc=xmem flag::
+
+ ./x86_64-native-linuxapp-gcc/app/testpmd -c 0xf -n 4 -- --mp-alloc=xmem -i
+
+Start forward in testpmd
+
+Start send traffic from outside to test the forward function
+
+
+Test case 4: VFIO and anonymous hugepage memory allocation
+-----------------------------------------------------------
+Bind the ports to vfio-pci driver
+
+Start testpmd with --mp-alloc=xmemhuge flag::
+
+ ./x86_64-native-linuxapp-gcc/app/testpmd -c 0xf -n 4 -- --mp-alloc=xmemhuge -i
+
+Start forward in testpmd
+
+Start send traffic from outside to test the forward function
