I know the rest of the file does not document the functions
prototypes, but I think it could be helpful to add doxygen-style
comments for new functions.

I'm not sure the .map should be modified like this, instead I
would have added a new DPDK_2.1 section, like I did for this
commit (reviewed by Neil):
http://dpdk.org/browse/dpdk/commit/?id=bbd778248985e542175e9b4ce560f2d379e78c4e

By the way, the following link is a good documentation about the
.map files:
