Subject: Re: [dts] [PATCH V4] stop port before csum set
Date: Tue, 30 Jan 2018 02:27:42 +0000 [thread overview]

Hi Marvin,
In this case ,we don't need set csum related offload when start testpmd.
When we run command "csum set ip/udp/tcp/sctp hw $port_id", dpdk will set csum offload.
And we run command "csum set ip/udp/tcp/sctp sw $port_id", dpdk will remove csum offload.

Gang,
You forgot to add tx offloads in this patch.
+ "--port-topology=loop --tx-offloads=0x1e", socket=self.ports_socket)
