BNXT Poll Mode Driver
|
||||
=====================
|
||||
|
||||
The bnxt poll mode library (**librte_pmd_bnxt**) implements support for:
|

The BNXT PMD (**librte_pmd_bnxt**) implements support for adapters based on
|
||||
Ethernet controllers and SoCs belonging to the **Broadcom BCM5730X NetXtreme-C®
|
||||
Family of Ethernet Network Controllers**, the **Broadcom BCM574XX/BCM575XX
|
||||
NetXtreme-E® Family of Ethernet Network Controllers**, the **Broadcom BCM588XX
|
||||
Stingray Family of SmartNIC Adapters**, and the **Broadcom StrataGX® BCM5871X
|
||||
Series of Communications Processors**. A complete list with links to reference
|
||||
material is included below.
|
||||
|
||||
* **Broadcom NetXtreme-C®/NetXtreme-E®/NetXtreme-S®
|
||||
BCM5730X / BCM574XX / BCM58000 / BCM575XX family of Ethernet Network Controllers**
|
||||
|
||||
Adapters based on this family of controllers support standards-compliant Ethernet
|
||||
operation with link speeds of 10/25/50/100/200Gbps.
|
||||
BNXT PMD Features
|
||||
-----------------
|
||||
|
||||
Information about the NetXtreme family of adapters can be found in the
|
||||
`NetXtreme® Brand section
|
||||
<https://www.broadcom.com/products/ethernet-connectivity/controllers/>`_
|
||||
The BNXT PMD includes support for the following features:
|
||||
|
||||
* Multiple transmit and receive queues
|
||||
* Queue start/stop
|
||||
* RSS hash
|
||||
* RSS key configuration
|
||||
* RSS reta configuration
|
||||
* VMDq
|
||||
* Packet type parsing
|
||||
* Configurable RX CRC stripping
|
||||
* L3/L4 checksum offload
|
||||
* LRO offload
|
||||
* TSO offload
|
||||
* VLAN offload
|
||||
* SR-IOV VF
|
||||
* Basic and extended port statistics
|
||||
* Link state reporting
|
||||
* Flow control
|
||||
* Ethertype filtering
|
||||
* N-tuple filtering
|
||||
* Promiscuous mode
|
||||
* Unicast and multicast MAC filtering
|
||||
* Scatter/gather transmit and receive
|
||||
* Jumbo frames
|
||||
* Vector PMD
|
||||
|
||||
BNXT Vector PMD
|
||||
---------------
|
||||
|
||||
The BNXT PMD includes support for SSE vector mode on x86 platforms. Vector
|
||||
provides significantly improved performance over the base implementation,
|
||||
however it does not support all of the features that are supported by the
|
||||
base (non-vector) implementation. Vector mode will be selected and enabled
|
||||
automatically when the port is started if allowed by the current configuration.
|
||||
|
||||
RX Requirements for Vector Mode
|
||||
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
||||
|
||||
Vector mode receive will be enabled if the following constrainsts are met:
|
||||
* Packets must fit within a single mbuf (no scatter RX).
|
||||
* LRO offload must be disabled.
|
||||
|
||||
TX Requirements for Vector Mode
|
||||
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
||||
|
||||
Vector mode transmit will be enabled if the following constrainsts are met:
|
||||
* Packets must be contained within a single mbuf (no gather TX).
|
||||
* All transmit offloads other than VLAN insertion must be disabled.
|
||||
|
||||

Limitations
|
||||
-----------
|
||||
|
||||
With the current driver, allocated mbufs must be large enough to hold
|
||||
the entire received frame. If the mbufs are not large enough, the
|
||||
packets will be dropped. This is most limiting when jumbo frames are
|
||||
used.
