Subject: [dpdk-dev] AF_PACKET poll mode driver
Date: Tue, 12 Apr 2016 10:56:34 +0000	[thread overview]
Message-ID: <BY2PR0301MB1542037F2D4C1E51447529F3B7950@BY2PR0301MB1542.namprd03.prod.outlook.com> (raw)

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:
