The current code performed this per batch and did this on copied packet data. Make it simpler and faster by validating it at once and on the umem packet data thus skipping the copy and the memory allocation for the temprary buffer. The optional packet dump feature is also simplified in the same manner. Memory allocation and copying is removed and the dump is performed directly on the umem data.

The idea is that a test generates one or more packet specifications and provides it/them to both Tx and Rx. The Tx thread will generate from this specification and Rx will validate that it receives what is in the specification. The specification can be the same on both ends, meaning that everything that was sent should be received, or different which means that Rx will only receive part of the sent packets. Currently, the packet specification is the same for both Rx and Tx and the same for each test. This will change in later patches as features and tests are added. The data path functions are also renamed to better reflect what actions they are performing after introducing this feature.
