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.
