Vlan tagging doesn't work for me

[sv3n-mu3ll3r]

Hello everybody,

I'm using MoonGen with Vmware and a Mellanox ConnectX-5 card. Untagged, I can send traffic though SR-IOV. But because I want other guests use the same card, I need to send the traffic tagged.

I added "buf:setVlan(3006)" to the code and hoped it would send traffic tagged with VlanID 3006. But it doesn't seem to be the case.

Do I miss anything?

Thanks a lot, sVen

while mg.running() do
-- fill packets and set their size
bufs:alloc(packetLen)
for i, buf in ipairs(bufs) do
buf:setVlan(3006)
local pkt = buf:getTcpPacket(ipv4)
--increment IP
if ipv4 then
pkt.ip4.src:set(minIP)
pkt.ip4.src:add(counter)
else
pkt.ip6.src:set(minIP)
pkt.ip6.src:add(counter)
end
counter = incAndWrap(counter, numIPs)

                    -- dump first 3 packets
                    if c < 1 then
                            buf:dump()
                            c = c + 1
                    end
            end
            --offload checksums to NIC
            bufs:offloadTcpChecksums(ipv4)
            queue:send(bufs)
            txStats:update()
    end
