 For example, if your EAL coremask is 0xff0, the master core will usually be the first core in the coremask (0x10); this is what you have to supply to taskset::
 
-   taskset 0x10 ./l2fwd -c 0xff0 -n 2
+   taskset 0x10 ./l2fwd -l 4-11 -n 2

+.. Note: Instead of '-c 0xff0' use the '-l 4-11' as a cleaner way to define lcores.
 
 In this way, the hugepages have a greater chance of being allocated to the correct socket.
 Additionally, a ``--socket-mem`` option could be used to ensure the availability of memory for each socket, so that if hugepages were allocated on
