class NetTuningPlugin(hotplug.Plugin):
	"""
	`net`::
	
	Configures network driver, hardware and Netfilter settings.
	Dynamic change of the interface speed according to the interface
	utilization is also supported. The dynamic tuning is controlled by
	the [option]`dynamic` and the global [option]`dynamic_tuning`
	option in `tuned-main.conf`.
	+
	The [option]`wake_on_lan` option sets wake-on-lan to the specified
	value as when using the `ethtool` utility.
	+
	.Set Wake-on-LAN for device eth0 on MagicPacket(TM)
	====
	----
	[net]
	devices=eth0
	wake_on_lan=g
	----
	====
	+
	The [option]`coalesce` option allows changing coalescing settings
	for the specified network devices. The syntax is:
	+
	[subs="+quotes,+macros"]
	----
	coalesce=__param1__ __value1__ __param2__ __value2__ ... __paramN__ __valueN__
	----
	Note that not all the coalescing parameters are supported by all
	network cards. For the list of coalescing parameters of your network
	device, use `ethtool -c device`.
	+	
	.Setting coalescing parameters rx/tx-usecs for all network devices
	====
	----
	[net]
	coalesce=rx-usecs 3 tx-usecs 16
	----
	====
	+
	The [option]`features` option allows changing 
	the offload parameters and other features for the specified
	network devices. To query the features of your network device,
	use `ethtool -k device`. The syntax of the option is the same as
	the [option]`coalesce` option.
	+
	.Turn off TX checksumming, generic segmentation and receive offload 
	====
	----
	[net]
	features=tx off gso off gro off
	----
	====
	The [option]`pause` option allows changing the pause parameters for
	the specified network devices. To query the pause parameters of your
	network device, use `ethtool -a device`. The syntax of the option
	is the same as the [option]`coalesce` option.
	+
	.Disable autonegotiation
	====
	----
	[net]
	pause=autoneg off
	----
	====
	+
	The [option]`ring` option allows changing the rx/tx ring parameters
	for the specified network devices. To query the ring parameters of your
	network device, use `ethtool -g device`. The syntax of the option
	is the same as the [option]`coalesce` option.
	+	
	.Change the number of ring entries for the Rx/Tx rings to 1024/512 respectively
	=====
	-----
	[net]
	ring=rx 1024 tx 512
	-----
	=====
	+
	The [option]`channels` option allows changing the numbers of channels
	for the specified network device. A channel is an IRQ and the set
	of queues that can trigger that IRQ. To query the channels parameters of your
	network device, use `ethtool -l device`. The syntax of the option
	is the same as the [option]`coalesce` option.
	+
	.Set the number of multi-purpose channels to 16
	=====
	-----
	[net]
	channels=combined 16
	-----
	=====
	+   
	A network device either supports rx/tx or combined queue
	mode. The [option]`channels` option automatically adjusts the
	parameters based on the mode supported by the device as long as a
	valid configuration is requested.
	+
	The [option]`nf_conntrack_hashsize` option sets the size of the hash
	table which stores lists of conntrack entries by writing to
	`/sys/module/nf_conntrack/parameters/hashsize`.
	+
	.Adjust the size of the conntrack hash table
	====
	----
	[net]
	nf_conntrack_hashsize=131072
	----
	====
	+
	The [option]`txqueuelen` option allows changing txqueuelen (the length
	of the transmit queue). It uses `ip` utility that is in package	iproute
	recommended for TuneD, so the package needs to be installed for its correct
	functionality. To query the txqueuelen parameters of your network device
	use `ip link show` and the current value is shown after the qlen column.
	+
	.Adjust the length of the transmit queue
	====
	----
	[net]
	txqueuelen=5000
	----
	====
	+
	The [option]`mtu` option allows changing MTU (Maximum Transmission Unit).
	It uses `ip` utility that is in package	iproute recommended for TuneD, so
	the package needs to be installed for its correct functionality. To query
	the MTU parameters of your network device use `ip link show` and the
	current value is shown after the MTU column.
	+
	.Adjust the size of the MTU
