+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 cases:
+-----------
+
+Test case 1: IGB_UIO and anonymous memory allocation
+steps:
+1. bind the ports to IGB_UIO driver;
+2. start testpmd with --mp-alloc=xmem flag:
+# ./x86_64-native-linuxapp-gcc/app/testpmd -c 0xf -n 4 -- --mp-alloc=xmem -i
+3. start forward in testpmd;
+4. start send traffic from outside to test the forward function;
+
+Test case 2: IGB_UIO and anonymous hugepage memory allocation
+steps:
+1. bind the ports to IGB_UIO driver;
+2. start testpmd with --mp-alloc=xmemhuge flag:
+# ./x86_64-native-linuxapp-gcc/app/testpmd -c 0xf -n 4 -- --mp-alloc=xmemhuge -i
+3. start forward in testpmd;
+4. start send traffic from outside to test the forward function;
+
+Test case 3: VFIO and anonymous memory allocation
+steps:
+1. bind the ports to vfio-pci driver;
+2. start testpmd with --mp-alloc=xmem flag:
+# ./x86_64-native-linuxapp-gcc/app/testpmd -c 0xf -n 4 -- --mp-alloc=xmem -i
+3. start forward in testpmd;
+4. start send traffic from outside to test the forward function;
+
+Test case 4: VFIO and anonymous hugepage memory allocation
+steps:
+1. bind the ports to vfio-pci driver;
+2. start testpmd with --mp-alloc=xmemhuge flag:
+# ./x86_64-native-linuxapp-gcc/app/testpmd -c 0xf -n 4 -- --mp-alloc=xmemhuge -i
+3. start forward in testpmd;
+4. start send traffic from outside to test the forward function;
