[dpdk-users] Assigning queues according to MAC or VLAN

[tom.barbette]

Hi all,

I'm trying to dispatch packets to queue according to VLAN or MAC address with Intel 82599 cards. But the question remains general.

I tried MAC-VLAN flow director mode but it seems unsupported by those cards and Intel XL710 ones also (With testpmd, 82599 refuse to initialize and I get operation not supported for XL710). Is it really an hardware limitation or should support be coming soon?

With VMDq, I could create pools with MAC/VLAN filters but the problem is that MAC and VLAN assignation are static, at initialization time. I'd prefer a dynamic solution where I can change filtering parameters while running.

Last resort seems to use VFs, but it's a bit overkill and I'm not sure about the performance penalty. Is it my only option?

Thanks,

Tom

Hi,

I face a similar problem with Tom, could you please shed some light on this
issue? Dynamicity and performance are my two concerns as well.

Thanks,
Georgios
