Dear developers! I have some troubles with VDMQ configuring.
Goal: I want to split physical port to 2 virtual depend on vlan. I need
rss (32 queues on each virtual port, and 32 queues for untagged packets)
and keep LLDP, LACP/LAG functionality.
so i need 3 Rss group, each 32 queues (Untagged, Vlan A, Vlan B)
hardware and OS:
Xeon E5 2695 v4, X710 4X10Gb (firmware 6.8), Ubunti server 18.04 LTS,
dpdk 19.02
I am trying to configure VMDQ with rss.
DPDK config changes:
CONFIG_RTE_LIBRTE_I40E_QUEUE_NUM_PER_PF=32
CONFIG_RTE_LIBRTE_I40E_QUEUE_NUM_PER_VM=32
Then i configured 8 pools and all queues( queues, that i am not going to
use i configured with pool, that i am not going to use (to save some
memory))
Then i filled rte_eth_vmdq_rx_conf strcut. It has field "rx_mode", where
i set 0 ( so i set nither ETH_VMDQ_ACCEPT_UNTAG not
ETH_VMDQ_ACCEPT_BROADCAST );
I expect, that i will have packets with vlan Tag A on queues 32-63,
with Tag B qeueus 64-95 and UNTAG traffic on queues 0-31 with RSS.
It works, but some packets appear on each pool , like ( Ether(dst=
"ff:ff:ff:ff:ff:ff:ff")/IP(dst="255.255.255.255")).
I looked in i40e driver code, and found, that driver ignore field
"rx_mode".
Questions
1. Is it bug? If Yes, when it will be fixed?
2. Has this case workaround ? (maby i can do it with vlan mirroring? )
If Yes, can you help me with configuration? ( I will be glad to have
simple example with mirroring)
3. Maby i can fix it by myself? (so i need few words about, what should
i do?
