Subject: [PATCH 2/2] ethdev: introduce the mhpsdp hwport field in Tx queue API
Date: Sat, 28 Jan 2023 15:08:57 +0200 [thread overview]
Message-ID: <20230128130857.17399-3-jiaweiw@nvidia.com> (raw)
In-Reply-To: <20230128130857.17399-1-jiaweiw@nvidia.com>
For the multiple hardware ports connect to a single DPDK port (mhpsdp),
the previous patch introduces the new rte flow item to match the
hardware port of the received packets.
This patch adds the tx_mhpsdp_hwport setting in Tx queue API, the hwport
value reflects packets be sent to which hardware port.
0 is no port assigned and traffic will be routed between different hardware
ports, if 0 is disabled then try to match on MHPSDP_HW_PORT with 0 will
result in an error.
Adds the new tx_mhpsdp_hwport field into the padding hole of rte_eth_txconf
structure, the size of rte_eth_txconf keeps the same. Adds a suppress
type for structure change in the ABI check file.
This patch adds the testpmd command line:
testpmd> port config (port_id) txq (queue_id) mhpsdp_hwport (value)
For example, there're two hardware ports 0 and 1 connected to
a single DPDK port (port id 0), and mhpsdp_hwport 1 stood for
hardware port 0 and mhpsdp_hwport 2 stood for hardware port 1,
used the below command to config tx mhpsdp_hwport for per Tx Queue:
port config 0 txq 0 mhpsdp_hwport 1
port config 0 txq 1 mhpsdp_hwport 1
port config 0 txq 2 mhpsdp_hwport 2
port config 0 txq 3 mhpsdp_hwport 2
These commands config the TxQ index 0 and TxQ index 1 with mhpsdp_hwport 1,
uses TxQ 0 or TxQ 1 send packets, these packets will be sent from the
hardware port 0, and similar with hardware port 1 if sending packets
with TxQ 2 or TxQ 3.
