 The CPUfreq govenor "ondemand" sets the CPU depending on the
 current usage. To do this the CPU must have the capability to

+switch the frequency very quickly.  There are a number of sysfs file
+accessible parameters:
+
+sampling_rate: measured in uS (10^-6 seconds), this is how often you
+want the kernel to look at the CPU usage and to make decisions on
+what to do about the frequency.  Typically this is set to values of
+around '10000' or more.
+
+show_sampling_rate_(min|max): the minimum and maximum sampling rates
+available that you may set 'sampling_rate' to.
+
+up_threshold: defines what the average CPU usaged between the samplings
+of 'sampling_rate' needs to be for the kernel to make a decision on
+whether it should increase the frequency.  For example when it is set
+to its default value of '80' it means that between the checking
+intervals the CPU needs to be on average more than 80% in use to then
+decide that the CPU frequency needs to be increased.  
+
+sampling_down_factor: this parameter controls the rate that the CPU
+makes a decision on when to decrease the frequency.  When set to its
+default value of '5' it means that at 1/5 the sampling_rate the kernel
+makes a decision to lower the frequency.  Five "lower rate" decisions
+have to be made in a row before the CPU frequency is actually lower.
+If set to '1' then the frequency decreases as quickly as it increases,
+if set to '2' it decreases at half the rate of the increase.
+
+ignore_nice_load: this parameter takes a value of '0' or '1', when set
+to '0' (its default) then all processes are counted towards towards the
+'cpu utilisation' value.   When set to '1' then processes that are
+run with a 'nice' value will not count (and thus be ignored) in the
+overal usage calculation.  This is useful if you are running a CPU
+intensive calculation on your laptop that you do not care how long it
+takes to complete as you can 'nice' it and prevent it from taking part
+in the deciding process of whether to increase your CPU frequency.
 
 
+2.5 Conservative
+----------------
+
+The CPUfreq governor "conservative", much like the "ondemand"
+governor, sets the CPU depending on the current usage.  It differs in
+behaviour in that it gracefully increases and decreases the CPU speed
+rather than jumping to max speed the moment there is any load on the
+CPU.  This behaviour more suitable in a battery powered environment.
+The governor is tweaked in the same manner as the "ondemand" governor
+through sysfs with the addition of:
+
+freq_step: this describes what percentage steps the cpu freq should be
+increased and decreased smoothly by.  By default the cpu frequency will
+increase in 5% chunks of your maximum cpu frequency.  You can change this
+value to anywhere between 0 and 100 where '0' will effectively lock your
+CPU at a speed regardless of its load whilst '100' will, in theory, make
+it behave identically to the "ondemand" governor.
+
+down_threshold: same as the 'up_threshold' found for the "ondemand"
+governor but for the opposite direction.  For example when set to its
+default value of '20' it means that if the CPU usage needs to be below
+20% between samples to have the frequency decreased.

+The Gianfar Ethernet Driver
+Sysfs File description
+
+Author: Andy Fleming <afleming@freescale.com>
+Updated: 2005-07-28
+
+SYSFS
+
+Several of the features of the gianfar driver are controlled
+through sysfs files.  These are:
+
+bd_stash:
+To stash RX Buffer Descriptors in the L2, echo 'on' or '1' to
+bd_stash, echo 'off' or '0' to disable
+
+rx_stash_len:
+To stash the first n bytes of the packet in L2, echo the number
+of bytes to buf_stash_len.  echo 0 to disable.
+
+WARNING: You could really screw these up if you set them too low or high!
+fifo_threshold:
+To change the number of bytes the controller needs in the
+fifo before it starts transmission, echo the number of bytes to 
+fifo_thresh.  Range should be 0-511.
+
+fifo_starve:
+When the FIFO has less than this many bytes during a transmit, it
+enters starve mode, and increases the priority of TX memory
+transactions.  To change, echo the number of bytes to
+fifo_starve.  Range should be 0-511.
+
+fifo_starve_off:
+Once in starve mode, the FIFO remains there until it has this
+many bytes.  To change, echo the number of bytes to
+fifo_starve_off.  Range should be 0-511.
+
+CHECKSUM OFFLOADING
+
+The eTSEC controller (first included in parts from late 2005 like
+the 8548) has the ability to perform TCP, UDP, and IP checksums
+in hardware.  The Linux kernel only offloads the TCP and UDP
+checksums (and always performs the pseudo header checksums), so
+the driver only supports checksumming for TCP/IP and UDP/IP
+packets.  Use ethtool to enable or disable this feature for RX
+and TX.
+
+VLAN
+
+In order to use VLAN, please consult Linux documentation on
+configuring VLANs.  The gianfar driver supports hardware insertion and
+extraction of VLAN headers, but not filtering.  Filtering will be
+done by the kernel.
+
+MULTICASTING
+
+The gianfar driver supports using the group hash table on the
+TSEC (and the extended hash table on the eTSEC) for multicast
+filtering.  On the eTSEC, the exact-match MAC registers are used
+before the hash tables.  See Linux documentation on how to join
+multicast groups.
+
+PADDING
+
+The gianfar driver supports padding received frames with 2 bytes
+to align the IP header to a 16-byte boundary, when supported by
+hardware.
+
+ETHTOOL
+
+The gianfar driver supports the use of ethtool for many
+configuration options.  You must run ethtool only on currently
+open interfaces.  See ethtool documentation for details.

+
+	Using a very small value, e.g. 1 or 2, for ipfrag_max_dist can
