> Currently in DPDK, any checks for the presence or absense of specific
> CPU flags has to be enclosed in #ifdef blocks, since the flags are
> conditionally defined per architecture as enums. This set attempts to
> improve this situation by allowing the flags to be queried as strings,
> with a CPU architecture type also specified. One new public API is
> provided for this. [Other APIs used by that are internal for now, but
> have an rte_ prefix in case we want to expose them publically later]
> 
> To test out this new functionality the crc code in the net library is
> updated to use this, demonstrating how the code can be simplified and
> the use of #ifdef's reduced.
