+                                               "native, anon or xmem\n",

Should xmemhuge be added to above line?


Yes :)

Thanks, will fix.

The following checkpatch warnings is testpmd.c should probably be fixed.

These should be ignored (and they indeed are ignored by DPDK's own 
checkpatch script). Strings are allowed to go over 80 characters so as 
to not make it hard to grep for them.
