Re: [dpdk-users] flow_filtering failed on mlx5

[Ori Kam <orika@mellanox.com>]

Just verified by running the code at least in Mellanox there is no difference.

Best,

The example code used to allow a VLAN tag, but with this patch it seems like it will not anymore. I'm on a connectx-5. Should we set the mask to NULL to achieve the same functionality as before?

Thanks

Glad to help,

That’s depends on the NIC but normally it should just be ETH / IPV4 traffic.

Thanks Ori! I'll test out the patch today. Just to make sure, by removing the vlan item, does that not allow vlan tags anymore, or is it just ignoring one if present?
