There is a long term goal to remove rte_memcpy(). It exists only as workaround for
cases where older compilers do not produce optimium code. 

When rte_memcpy() is used the checks done by fortify, gcc, coverity etc are
less and there is higher probability of bugs going undetected.

My current recommendation is to only use rte_memcpy() in the data path and for
variable size data items.
