Subject: [dpdk-users] How to configure an Ethernet Driver to ignore the Ethertype
Date: Fri, 21 Feb 2020 11:19:37 -0800	[thread overview]
Message-ID: <CAJC5fi1-Opa9Ux6P=emry0ypoMh95Jj78-=CGXURd4fcVVXsaQ@mail.gmail.com> (raw)

Hi,

I was wondering if there is a way to get the Ethernet driver to ignore the
Ethertype. The problem I am having is that I am dealing with a switch chip
that is redirecting packets to the processor via an offload ethernet
device. Before offload the switch chip adds a header that pushes the DA
into the spot where the EtherType is normally. As a result, the ethertype
is essentially a random value so some packets will look like that have a
snap header and the driver will conclude that the packet is corrupted I
presume. I am working with the IXGBE driver.

Any ideas?

Thanks,

Jim
