[dpdk-dev] multiple VLAN IDs for SR-IOV ports

[Patel, Rashmin N]

I haven't checked it with ip tool. But I just verified from the Niantic specs, and I see PFVLVF[64] and PFVLVFB[128] - 32 bit register arrays to configure VLAN-Pool/VF mapping.
PFVLVF[i] holds a vlan_id need to be mapped
PFVLVFB[2i] and PFVLVFB[2i+1] holds bitmap for max possible pools (64 bits) to map any of those pools to the PFVLVF[i].vlan_id

So technically you should be able to map it, the only thing I'm not sure if it's supported with ip tool or not.
If you quickly want to check it out, you can just write those registers through PCI bar.

Thanks,
Rashmin

Patel,

I can use the following command to add one VLAN with VID of 3 to VF 0 of
eth6

ip link set eth6 vf 0 vlan 3

Could you show me an example of adding 2 VLAN IDs such as VID of 3 and 13 to the same VF 0 ? I want VF 0 to pass traffic from VLAN 3 and 13. How do I do that ?
>From the man page of ip, I do not see it describes about adding more than one VLAN IDs to the same VF port.
Can I use this ?
ip link set eth6 vf0 vlan 3,13


Thanks

James
