Hello,
Is it possible to enable RSS for QinQ traffic for Intel XL710-QDA2?
I'm trying to set following configuration on my NIC Intel XL710-QDA2
I want to:
1. Receive QinQ traffic
2. Steer traffic using RSS on the NIC
3. Extract both vlan tags.
I can receive both tags from the NIC, but RSS hash is always 0, and
there's no RSS steering between queues.
If I disable VLAN strip offloading I see that hash is calculated, but
its value is always the same.
My NIC is Intel XL710-QDA2. Latest fw and driver.
static const struct rte_eth_conf port_conf = {
.rxmode = {
.mq_mode = ETH_MQ_RX_RSS,
.max_rx_pkt_len = ETHER_MAX_LEN,
.split_hdr_size = 0,
.header_split = 0, /**< Header Split disabled */
.hw_ip_checksum = 1, /**< IP checksum offload enabled */
.hw_vlan_filter = 0, /**< VLAN filtering disabled */
.hw_vlan_strip = 1,
.jumbo_frame = 0, /**< Jumbo Frame Support disabled */
.hw_strip_crc = 0, /**< CRC stripped by hardware */
},
.rx_adv_conf = {
.rss_conf = {
.rss_key = NULL,
.rss_hf = ETH_RSS_PROTO_MASK,
},
},
}
Thanks
