Does F-stack support ENA on AWS?

[zcuder]

hi fstack experts,
currently I am setting up f-stack on aws, while it is using Elastic Network Adapter（ENA） on AWS.
dpdk/usertools/dpdk-devbind.py -s

Network devices using DPDK-compatible driver

0000:00:06.0 'Elastic Network Adapter (ENA) ec20' drv=igb_uio unused=ena

I am trying to setup the demo program. but it fails saying not support promiscuous mode
./dpdk/build/app/dpdk-testpmd

Not sure if this error is relating to F-stack supporting ENA issue, or might be something else misconfigured.
Any help would be appreciated
