Hello Bruce,

I don't know to be honest. I didn't know the reasoning behind not 
including crypto code for Intel for example. I thought it was due to 
licensing and code control rather than export compliance.

Maybe someone from the DPDK community will know what are the constraints 
related to including crypto algorithms to DPDK.

Kind regards
