Subject: [PATCH v6 1/2] ethdev: add Tx queue mapping of aggregated ports
Date: Fri, 17 Feb 2023 12:50:25 +0200	[thread overview]
Message-ID: <20230217105026.12927-2-jiaweiw@nvidia.com> (raw)
In-Reply-To: <20230217105026.12927-1-jiaweiw@nvidia.com>

When multiple ports are aggregated into a single DPDK port,
(example: Linux bonding, DPDK bonding, failsafe, etc.),
we want to know which port use for Tx via a queue.

This patch introduces the new ethdev API
rte_eth_dev_map_aggr_tx_affinity(), it's used to map a Tx queue
with an aggregated port of the DPDK port (specified with port_id),
The affinity is the number of the aggregated port.
Value 0 means no affinity and traffic could be routed to any
aggregated port, this is the default current behavior.

The maximum number of affinity is given by rte_eth_dev_count_aggr_ports().

Add the trace point for ethdev rte_eth_dev_count_aggr_ports()
and rte_eth_dev_map_aggr_tx_affinity() functions.

Add the testpmd command line:
testpmd> port config (port_id) txq (queue_id) affinity (value)

For example, there're two physical ports connected to
a single DPDK port (port id 0), and affinity 1 stood for
the first physical port and affinity 2 stood for the second
physical port.
Use the below commands to config tx phy affinity for per Tx Queue:
        port config 0 txq 0 affinity 1
        port config 0 txq 1 affinity 1
        port config 0 txq 2 affinity 2
        port config 0 txq 3 affinity 2

These commands config the Tx Queue index 0 and Tx Queue index 1 with
phy affinity 1, uses Tx Queue 0 or Tx Queue 1 send packets,
these packets will be sent from the first physical port, and similar
with the second physical port if sending packets with Tx Queue 2
or Tx Queue 3.
