These variables must be set before loading the driver, either via
loader.conf(5)
or through the use of
kenv(1).
These are provided by the
iflib(4)
framework, and might be better documented there.
|
| dev.bnxt.X.iflib.override_nrxds
|
| |
Override the number of RX descriptors for each queue.
The value is a comma separated list of three positive integers: the size of the
completion ring,
the size of the receive ring, and the size of the aggregation ring respectively.
The completion ring should be at least the size of the aggregation ring plus
four times the size of the receive ring.
These numbers must be powers of two, and zero means to use the default.
Defaults to 0,0,0.
|
| dev.bnxt.X.iflib.override_ntxds
|
| |
Override the number of TX descriptors for each queue.
The value is a comma separated list of two positive integers: the size of the
completion ring, and the size of the transmit ring respectively.
The completion ring should be at least twice the size of the transmit ring.
These numbers must be powers of two, and zero means to use the default.
Defaults to 0,0.
|
| dev.bnxt.X.iflib.override_qs_enable
|
| |
When set, allows the number of transmit and receive queues to be different.
If not set, the lower of the number of TX or RX queues will be used for both.
|
| dev.bnxt.X.iflib.override_nrxqs
|
| |
Set the number of RX queues.
If zero, the number of RX queues is derived from the number of cores on the
socket connected to the controller.
Defaults to 0.
|
| dev.bnxt.X.iflib.override_ntxqs
|
| |
Set the number of TX queues.
If zero, the number of TX queues is derived from the number of cores on the
socket connected to the controller.
|
|
These
sysctl(8)
variables can be changed at any time:
| dev.bnxt.X.vlan_only
|
| |
Require that incoming frames must have a VLAN tag on them that matches one that
is configured for the NIC.
Normally, both frames that have a matching VLAN tag and frames that have no
VLAN tag are accepted.
Defaults to 0.
|
| dev.bnxt.X.vlan_strip
|
| |
When non-zero the NIC strips VLAN tags on receive.
Defaults to 0.
|
| dev.bnxt.X.rx_stall
|
| |
Enable buffering rather than dropping frames when there are no available host
RX buffers for DMA.
Defaults to 0.
|
| dev.bnxt.X.rss_type
|
| |
Comma-separated list of RSS hash types to support.
Default is all types.
Defaults to ipv4,tcp_ipv4,udp_ipv4,ipv6,tcp_ipv6,udp_ipv6.
|
| dev.bnxt.X.rss_key
|
| |
Current RSS key.
Defaults to a randomly generated value which is generated for each device
during attach.
|
| dev.bnxt.X.ver.hwrm_min_ver
|
| |
Minimum HWRM (HardWare Resource Manager) firmware API to support.
If the firmware implements an older version, a warning will be printed, and the
firmware should be upgraded.
Defaults to 1.2.2.
|
|
These
sysctl(8)
variables are read-only:
| dev.bnxt.X.if_name
|
| |
Current interface name of the device.
This will normally be
bnxtX,
but this can be changed using
ifconfig name.
This sysctl allows correlating an interface with a child of
dev.bnxt.
|
| dev.bnxt.X.nvram.*
|
| |
Information about the NVRAM device which contains the device firmware.
|
| dev.bnxt.X.ver.*
|
| |
Version-related information about the device and firmware:
|
| dev.bnxt.X.ver.hwrm_if
|
| |
Supported HWRM API version of the currently running firmware.
|
| dev.bnxt.X.ver.driver_hwrm_if
|
| |
HWRM API version the driver was built to support.
|
| dev.bnxt.X.hwstats.*
|
| |
Per-queue statistics tracked by the hardware.
|
| dev.bnxt.X.hwstats.port_stats.*
|
| |
Per-port statistics tracked by the hardware.
|
| dev.bnxt.X.hwstats.rxq0.drop_pkts
|
| |
Number of packets dropped by hardware on queue zero.
This number might seem high, but the count includes packets dropped due to
incorrect destination MAC, unsubscribed multicast address, and other normal
reasons to ignore Ethernet frames.
|
| dev.bnxt.X.hwstats.rxq0.tpa_*
|
| |
statistics related to HW LRO.
|
| dev.bnxt.X.hw_lro.*
|
| |
Enable / Disable HW LRO feature. Defaults to disable.
Enabling HW LRO could cause issues when forwarding is enabled on host.
|
| dev.bnxt.X.fc
|
| |
Enable / Disable Flow Control feature. Defaults to Enable
|
|
