multiple VLAN IDs for SR-IOV ports

multiple VLAN IDs for SR-IOV ports

[James Yu]

Any one know what commands to use on the KVM host to add multiple VLAN IDs
to a SR-IOV port ?

I could only add one VLAN ID using

ip link set ethN vf NUM vlan VLANID

Also do I have to call any routine on the DPDK side to add those VIDs ?

What do you mean by "multiple VLAN IDs" ?  ethN and vf NUM here let's you
add more than one vlan id.

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

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
