Hello Vidya Sagar,
As I answered in the case 00101328.
I suspect you didn't enable "DPA Offloading Drivers" driver in Linux Kernel or you didn't rebuild Linux kernel image with appropriate procedure.
Please make sure the following configuration is enabled in Kernel configuration(CONFIG_FSL_DPA_OFFLOAD=y).
Device Drivers
[*]Staging Drivers
<*> Freescale Datapath Offloading Driver
Please refer to the following procedure to rebuild Linux Kernel if you use Yocto Linux SDK.
1. $ bitbake virtual/kernel -c cleansstate
2. $ bitbake virtual/kernel -c configure
3. Go to Linux Kernel build folder
cd ~/test/QorIQ-SDK-V2.0-20160527-yocto/build_t2080rdb/tmp/work/t2080rdb-fsl-linux/linux-qoriq/4.1-r0/build/
4. $make ARCH=powerpc menuconfig
Enable the following configuration
Device Drivers
[*]Staging Drivers
<*> Freescale Datapath Offloading Driver
5. Rebuild Linux Kernel and get images in build_t2080rdb/tmp/deploy/images/t2080rdb/.
$ bitbake virtual/kernel
I have verified the above procedure to build the attached images and verified them on T2080RDB board. After the system sets up, /dev/dpa_classifier and /dev/dpa_stats are created.
Have a great day,
Yiping
