11. BNXT Poll Mode Driver
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.
11.1. BNXT PMD Features
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
11.2. 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.
11.2.1. 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.
11.2.2. 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.
