At the LNet layer check sums is done at the LND level if at all. Also when the LND driver do some level of check sum they use different non-standard algorithms from the other LND drivers. Because of this check sums need to be performed at the client, router and server destination. The router level check summing shouldn't be needed.</p> <p>This project aims to create a check summing layer for LNET that is above the LND drivers so it can cover all the network data instead of just bulk data. Secondly this will be handled independent of the LND drivers thus<br/> allowing us to avoid check summing on the routers.</p> LU-6034
