L3 layer encrypted packets drop in dpdk

I am using dpdk for encrypting IP Packet (IP payload) in L1046ardb Kit. At the receive side , the dpaa driver is dropping the encrypted packet (Not sure whether due to length corruption or checksum corruption as both are encrypted).

How do i disable dpaa not to drop any packets??

I tried the solution mentioned in this thread 

https://community.nxp.com/t5/Layerscape/checksum-disabling-in-dpaa-driver-in-dpdk/m-p/1283323#M8096

but am still not able to receive the packet at the application layer.

There are two methods for received L4 checksum error packet from Fman ports,
1. Disable Fman L3/L4 checksum. Unset "DEV_RX_OFFLOAD_CHECKSUM" of "port_conf.rxmode.offloads" to disable L3/L4 checksum for Fman when compile l3fwd application.


2. Receive the checksum error packets to error FQ with the attached patch.
