+IP: virtual server support
+CONFIG_IP_VS
+  IP Virtual Server support will let you build a high-performance
+  virtual server based on cluster of two or more real servers. This
+  option must be enabled for at least one of the clustered computers
+  that will take care of intercepting incomming connections to a
+  single IP address and scheduling them to real servers.
+
+  Three request dispatching techniques are implemented, they are
+  virtual server via NAT, virtual server via tunneling and virtual
+  server via direct routing. The several scheduling algorithms can
+  be used to choose which server the connection is directed to,
+  thus load balancing can be achieved among the servers.  For more
+  information and its administration program, please visit the
+  following URL:

+
+IPVS connection hash table size (the Nth power of 2)
+CONFIG_IP_VS_TAB_BITS
+  The IPVS connection hash table uses the chaining scheme to handle
+  hash collisions. Using a big IPVS connection hash table will greatly
+  reduce conflicts when there are hundreds of thousands of connections
+  in the hash table.
+
+  Note the table size must be power of 2. The table size will be the
+  value of 2 to the your input number power. The number to choose is
+  from 8 to 20, the default number is 12, which means the table size
+  is 4096. Don't input the number too small, otherwise you will lose
+  performance on it. You can adapt the table size yourself, according
+  to your virtual server application. It is good to set the table size
+  not far less than the number of connections per second multiplying
+  average lasting time of connection in the table.  For example, your
+  virtual server gets 200 connections per second, the connection lasts
+  for 200 seconds in average in the connection table, the table size
+  should be not far less than 200x200, it is good to set the table
+  size 32768 (2**15).
+
+  Another note that each connection occupies 128 bytes effectively and
+  each hash entry uses 8 bytes, so you can estimate how much memory is
+  needed for your box.
+
+IPVS: round-robin scheduling
+CONFIG_IP_VS_RR
+  The robin-robin scheduling algorithm simply directs network
+  connections to different real servers in a round-robin manner.
+
+  If you want to compile it in kernel, say Y. If you want to compile
+  it as a module, say M here and read Documentation/modules.txt. If
+  unsure, say N.
+
+IPVS: weighted round-robin scheduling
+CONFIG_IP_VS_WRR
+  The weighted robin-robin scheduling algorithm directs network
+  connections to different real servers based on server weights
+  in a round-robin manner. Servers with higher weights receive
+  new connections first than those with less weights, and servers
+  with higher weights get more connections than those with less
+  weights and servers with equal weights get equal connections.
+
+  If you want to compile it in kernel, say Y. If you want to compile
+  it as a module, say M here and read Documentation/modules.txt. If
+  unsure, say N.
+
+IPVS: least-connection scheduling
+CONFIG_IP_VS_LC
+  The least-connection scheduling algorithm directs network
+  connections to the server with the least number of active 
+  connections.
+
+  If you want to compile it in kernel, say Y. If you want to compile
+  it as a module, say M here and read Documentation/modules.txt. If
+  unsure, say N.
+
+IPVS: weighted least-connection scheduling
+CONFIG_IP_VS_WLC
+  The weighted least-connection scheduling algorithm directs network
+  connections to the server with the least active connections
+  normalized by the server weight.
+
+  If you want to compile it in kernel, say Y. If you want to compile
+  it as a module, say M here and read Documentation/modules.txt. If
+  unsure, say N.
+
+IPVS: locality-based least-connection scheduling
+CONFIG_IP_VS_LBLC
+  The locality-based least-connection scheduling algorithm is for
+  destination IP load balancing. It is usually used in cache cluster.
+  This algorithm usually directs packet destined for an IP address to
+  its server if the server is alive and under load. If the server is
+  overloaded (its active connection numbers is larger than its weight)
+  and there is a server in its half load, then allocate the weighted
+  least-connection server to this IP address.
+
+  If you want to compile it in kernel, say Y. If you want to compile
+  it as a module, say M here and read Documentation/modules.txt. If
+  unsure, say N.
+
+IPVS: locality-based least-connection with replication scheduling
+CONFIG_IP_VS_LBLCR
+  The locality-based least-connection with replication scheduling
+  algorithm is also for destination IP load balancing. It is 
+  usually used in cache cluster. It differs from the LBLC scheduling
+  as follows: the load balancer maintains mappings from a target
+  to a set of server nodes that can serve the target. Requests for
+  a target are assigned to the least-connection node in the target's
+  server set. If all the node in the server set are over loaded,
+  it picks up a least-connection node in the cluster and adds it
+  in the sever set for the target. If the server set has not been
+  modified for the specified time, the most loaded node is removed
+  from the server set, in order to avoid high degree of replication.
+
+  If you want to compile it in kernel, say Y. If you want to compile
+  it as a module, say M here and read Documentation/modules.txt. If
+  unsure, say N.
+
+IPVS: destination hashing scheduling
+CONFIG_IP_VS_DH
+  The destination hashing scheduling algorithm assigns network
+  connections to the servers through looking up a statically assigned
+  hash table by their destination IP addresses.
+
+  If you want to compile it in kernel, say Y. If you want to compile
+  it as a module, say M here and read Documentation/modules.txt. If
+  unsure, say N.
+
+IPVS: source hashing scheduling
+CONFIG_IP_VS_SH
+  The source hashing scheduling algorithm assigns network

+  hash table by their source IP addresses.
+
+  If you want to compile it in kernel, say Y. If you want to compile
+  it as a module, say M here and read Documentation/modules.txt. If
+  unsure, say N.
+
+IPVS: shortest expected delay scheduling
+CONFIG_IP_VS_SED
+  The shortest expected delay scheduling algorithm assigns network
+  connections to the server with the shortest expected delay. The 
+  expected delay that the job will experience is (Ci + 1) / Ui if 
+  sent to the ith server, in which Ci is the number of connections
+  on the the ith server and Ui is the fixed service rate (weight)
+  of the ith server.
+
+  If you want to compile it in kernel, say Y. If you want to compile
+  it as a module, say M here and read Documentation/modules.txt. If
+  unsure, say N.
+
+IPVS: never queue scheduling
+CONFIG_IP_VS_NQ
+  The never queue scheduling algorithm adopts a two-speed model.
+  When there is an idle server available, the job will be sent to
+  the idle server, instead of waiting for a fast one. When there
+  is no idle server available, the job will be sent to the server
+  that minimize its expected delay (The Shortest Expected Delay
+  scheduling algorithm).

+  it as a module, say M here and read Documentation/modules.txt. If
+  unsure, say N.
+
+IPVS: FTP protocol helper
+CONFIG_IP_VS_FTP
+  FTP is a protocol that transfers IP address and/or port number in
+  the payload. In the virtual server via Network Address Translation,
+  the IP address and port number of real servers cannot be sent to
+  clients in ftp connections directly, so FTP protocol helper is
+  required for tracking the connection and mangling it back to that of
+  virtual service.

+CONFIG_USB_GADGET
+  USB is a master/slave protocol, organized with one master
+  host (such as a PC) controlling up to 127 peripheral devices.
+  The USB hardware is asymmetric, which makes it easier to set up:
+  you can't connect two "to-the-host" connectors to each other.
+
+  Linux can run in the host, or in the peripheral.  In both cases
+  you need a low level bus controller driver, and some software
+  talking to it.  Peripheral controllers are often discrete silicon,
+  or are integrated with the CPU in a microcontroller.  The more
+  familiar host side controllers have names like like "EHCI", "OHCI",
+  or "UHCI", and are usually integrated into southbridges on PC
+  motherboards.
+
+  Enable this configuration option if you want to run Linux inside
+  a USB peripheral device.  Configure one hardware driver for your
+  peripheral/device side bus controller, and a "gadget driver" for
+  your peripheral protocol.  (If you use modular gadget drivers,
+  you may configure more than one.)
+
+  If in doubt, say "N" and don't enable these drivers; most people
+  don't have this kind of hardware (except maybe inside Linux PDAs).
+
+CONFIG_USB_NET2280
+  NetChip 2280 is a PCI based USB peripheral controller which
+  supports both full and high speed USB 2.0 data transfers.  
+           
+  It has six configurable endpoints, as well as endpoint zero
+  (for control transfers) and several endpoints with dedicated
+  functions.
+
+  Say "y" to link the driver statically, or "m" to build a
+  dynamically linked module called "net2280" and force all
+  gadget drivers to also be dynamically linked.
+
+CONFIG_USB_ZERO
+  Gadget Zero is a two-configuration device.  It either sinks and
+  sources bulk data; or it loops back a configurable number of
+  transfers.  It also implements control requests, for "chapter 9"
+  conformance.  The driver needs only two bulk-capable endpoints, so
+  it can work on top of most device-side usb controllers.  It's
+  useful for testing, and is also a working example showing how
+  USB "gadget drivers" can be written.
+
+  Make this be the first driver you try using on top of any new
+  USB peripheral controller driver.  Then you can use host-side
+  test software, like the "usbtest" driver, to put your hardware
+  and its driver through a basic set of functional tests.
+
+  Gadget Zero also works with the host-side "usb-skeleton" driver,
+  and with many kinds of host-side test software.  You may need
+  to tweak product and vendor IDs before host software knows about
+  this device, and arrange to select an appropriate configuration.
+
+  Say "y" to link the driver statically, or "m" to build a
+  dynamically linked module called "g_zero".
+
+CONFIG_USB_ETH
+  This driver implements Ethernet style communication, in either
+  of two ways:
+          
+   - The "Communication Device Class" (CDC) Ethernet Control Model.
+     That protocol is often avoided with pure Ethernet adapters, in
+     favor of simpler vendor-specific hardware, but is widely
+     supported by firmware for smart network devices.
+
+   - On hardware can't implement that protocol, a simpler approach
+     is used, placing fewer demands on USB.
+
+   Within the USB device, this gadget driver exposes a network device
+   "usbX", where X depends on what other networking devices you have.
+   Treat it like a two-node Ethernet link:  host, and gadget.
+
+   The Linux-USB host-side "usbnet" driver interoperates with this
+   driver, so that deep I/O queues can be supported.  On 2.4 kernels,
+   use "CDCEther" instead, if you're using the CDC option. That CDC
+   mode should also interoperate with standard CDC Ethernet class
+   drivers on other host operating systems.
+
+   Say "y" to link the driver statically, or "m" to build a
+   dynamically linked module called "g_ether".

+ttyS0 device
+CONFIG_UART0_TTYS0
+  This option reverses the mapping between the hardware UART and software

+
+PowerPC 405 on-chip ethernet -- Amount of bytes to Reserve on a skb
+CONFIG_IBM_OCP_ENET_SKB_RES
+  Many standard ethernet drivers need to reserve 2 bytes of data
+  on the skb before giving the data ptr to the hardware. This is
+  so the IP data will be 16-byte aligned when it goes up the stack.
+  This is a requirement for some processors and it can cause major
+  slow downs on others. The 405GP dose not have problems with the 
+  misaligned data so the default is 0. If you need to route the
+  incoming ethernet packets to another device that has alignment
+  requirements this can help remove a data copy. A value of 2 can
+  help at getting 16-byte aligned IP data for another device. A
+  larger value can be used when routing to a IP tunnel device.
+  Make sure XXX_DESC_SIZE - XXX_SKB_RES >= 1514, or larger if VLANS
+  are used.
