Hi,
We are facing a problem in DPDK - AF_PACKET poll mode driver.
We are able to create RAW socket and receive RTP-Signaling packets successfully
and our application is running fine.
But if we try doing scp to the same interface we are facing a crash.
The stack trace:

Please help us out regarding this issue.
