Instance Method Details

#defer_hard_irqs ⇒ Integer

The number of consecutive empty polls before IRQ deferral ends and hardware IRQs are re-enabled.

Returns:

  • (Integer)

# File 'nl-linux/generated/nl/linux/netdev.rb', line 2305

def defer_hard_irqs; attributes[:"defer_hard_irqs"]&.value; end

#gro_flush_timeout ⇒ Integer

The timeout, in nanoseconds, of when to trigger the NAPI watchdog timer which schedules NAPI processing. Additionally, a non-zero value will also prevent GRO from flushing recent super-frames at the end of a NAPI cycle. This may add receive latency in exchange for reducing the number of frames processed by the network stack.

Returns:

  • (Integer)

# File 'nl-linux/generated/nl/linux/netdev.rb', line 2310

def gro_flush_timeout; attributes[:"gro_flush_timeout"]&.value; end

#id ⇒ Integer

ID of the NAPI instance.

Returns:

  • (Integer)

See Also:

# File 'nl-linux/generated/nl/linux/netdev.rb', line 2290

def id; attributes[:"id"]&.value; end

#ifindex ⇒ Integer

ifindex of the netdevice to which NAPI instance belongs.

Returns:

  • (Integer)

See Also:



2285
 
# File 'nl-linux/generated/nl/linux/netdev.rb', line 2285

def ifindex; attributes[:"ifindex"]&.value; end

#irq ⇒ Integer

The associated interrupt vector number for the napi

Returns:

  • (Integer)

See Also:



2295
 
# File 'nl-linux/generated/nl/linux/netdev.rb', line 2295

def irq; attributes[:"irq"]&.value; end

#irq_suspend_timeout ⇒ Integer

The timeout, in nanoseconds, of how long to suspend irq processing, if event polling finds events

Returns:

  • (Integer)

See Also:



2315
 
# File 'nl-linux/generated/nl/linux/netdev.rb', line 2315

def irq_suspend_timeout; attributes[:"irq_suspend_timeout"]&.value; end

#pid ⇒ Integer

PID of the napi thread, if NAPI is configured to operate in threaded mode. If NAPI is not in threaded mode (i.e. uses normal softirq context), the attribute will be absent.

Returns:

  • (Integer)

See Also:



2300
 
# File 'nl-linux/generated/nl/linux/netdev.rb', line 2300

def pid; attributes[:"pid"]&.value; end

#threaded ⇒ Integer

Whether the NAPI is configured to operate in threaded polling mode. If this is set to enabled then the NAPI context operates in threaded polling mode. If this is set to busy-poll, then the threaded polling mode also busy polls.

Known enum values are defined in Enums::NapiThreaded.

Returns:

  • (Integer)

# File 'nl-linux/generated/nl/linux/netdev.rb', line 2322

def threaded; attributes[:"threaded"]&.value; end
