Subject: Re: [dpdk-users] OVS-DPDK -  af_packet vdev configuration - Error
Date: Mon, 19 Jun 2017 12:08:38 +0000	[thread overview]
Message-ID: <B84047ECBD981D4B93EAE5A6245AA361013C1F5A@FRAEML521-MBX.china.huawei.com> (raw)

OK - solved
The problem was with the  device MTU which is set in the af_packet to 1518, 
In my port creation I set its MTU to 9000
I've changed the MTU in the af_packet driver to 9000
