> 
> Added eBPF arm64 JIT support to improve the eBPF program performance
> on arm64.
> 
> dpdk.org/examples/bpf/t1.c application shows around 50% improvement
> on OCTEON TX2 platform in JIT vs interpreter mode.
> 
> Verified the implementation using existing bpf_autotest application.
> 
> # echo "bpf_autotest" | sudo ./build/app/test -c 0x3
