discussion mlx5e vlan forwarding

[Tonghao Zhang]

Hi Saeed and maintainers

In one case, I want to push vlan and forward the packets to one VF. Tc
command shown as below
$ tc filter add dev $PF0_REP0 parent ffff: protocol ip prio 1 chain 0 \
    flower src_mac 0a:47:da:d6:40:04 dst_mac 00:11:22:33:44:66 \
    action vlan push id 200 pipe action mirred egress redirect dev $PF_REP1

dmesg:
mlx5_core 0000:82:00.0: mlx5_cmd_check:756:(pid 10735):
SET_FLOW_TABLE_ENTRY(0x936) op_mod(0x0) failed, status bad
parameter(0x3), syndrome (0xa9c090)

So do we support that forwarding ?

kernel version: 5.6.0-rc7+ [OFED 5.0 has that issue too]
firmware-version: 16.27.1016
NIC: Mellanox Technologies MT27800 Family [ConnectX-5]

Hi Tonghao, 

CC'ing more experts, Or and Roi, they might have more useful info for
you.

but as far as i recall, this can only work on uplink port and not a VF.

Do we have plan to support that function? I guess that this feature is
important for us.
Because I use vlan id as metadata, and that will be matched in future.
