Hi All,
I am trying to build a multi-RX-queue dpdk program, using RSS to split the
incoming traffic into RX queues on a single port. Mellanox ConnectX-5 and
DPDK Version 19.11 is used for this purpose. It works fine when I use IP
over Ethernet packets as input. However when the packet contains IP over
MPLS over Ethernet, RSS does not seem to work. As a result, all packets
belonging to various flows (with different src & dst IPs, ports over MPLS)
are all sent into the same RX queue.
My queries are
1. Is there any parameter/techniques in DPDK to distribute MPLS packets to
multiple RX queues?
2. Is there any way to strip off MPLS tags (between Eth and IP) in
hardware, something like hw_vlan_strip?
My Port configuration is
const struct rte_eth_conf default_port_conf = {
.rxmode = {
.hw_vlan_strip = 0, /* VLAN strip enabled. */
.header_split = 0, /* Header Split disabled. */
.hw_ip_checksum = 0, /* IP checksum offload disabled. */
.hw_strip_crc = 0, /* CRC stripping by hardware disabled.
*/
},
.rx_adv_conf = {
.rss_conf = {
.rss_key = NULL,
.rss_key_len = 0,
.rss_hf = ETH_RSS_IP,
},
} };
