<abstract>
<para>
These books attempt to give a description of the
various subsystems that play a role in 802.11 wireless
networking in Linux. Since these books are for kernel
developers they attempts to document the structures
and functions used in the kernel as well as giving a
higher-level overview.
</para>
<para>
The reader is expected to be familiar with the 802.11
standard as published by the IEEE in 802.11-2007 (or
possibly later versions). References to this standard
will be given as "802.11-2007 8.1.5".

In some chapters, advanced usage is noted, that may be

functionality, additional information required to implement
the other modes is covered in the second part of the book.

<para>
This chapter shall contain information on getting a hw
struct allocated and registered with mac80211.
</para>
<para>
Since it is required to allocate rates/modes before registering
a hw struct, this chapter shall also contain information on setting
up the rate/mode structs.
</para>
<para>
Additionally, some discussion about the callbacks and
the general programming model should be in here, including
the definition of ieee80211_ops which will be referred to
a lot.
</para>
<para>
Finally, a discussion of hardware capabilities should be done
with references to other parts of the book.

for real-time and multimedia (streaming) traffic.
@ -29,9 +31,9 @@ It has a base protocol and pluggable congestion control IDs (CCIDs).

Other tunables
==============
Per-route rto_min support
CCID-2 supports the RTAX_RTO_MIN per-route setting for the minimum value
of the RTO timer. This setting can be modified via the 'rto_min' option
of iproute2; for example:
> ip route change 10.0.0.0/24 rto_min 250j dev wlan0
> ip route add 10.0.0.254/32 rto_min 800j dev wlan0
> ip route show dev wlan0
CCID-3 also supports the rto_min setting: it is used to define the lower
bound for the expiry of the nofeedback timer. This can be useful on LANs
with very low RTTs (e.g., loopback, Gbit ethernet).
Notes
=====
DCCP does not travel through NAT successfully at present on many boxes. This is
because the checksum covers the pseudo-header as per TCP and UDP. Linux NAT
support for DCCP has been added.

Phonet Pipe-controller Implementation
-------------------------------------
Phonet Pipe-controller is enabled by selecting the CONFIG_PHONET_PIPECTRLR Kconfig
option. It is useful when communicating with those Nokia Modems which do not
implement Pipe controller in them e.g. Nokia Slim Modem used in ST-Ericsson
U8500 platform.
The implementation is based on the Data Connection Establishment Sequence
depicted in 'Nokia Wireless Modem API - Wireless_modem_user_guide.pdf'
document.
It allows a phonet sequenced socket (host-pep) to initiate a Pipe connection
between itself and a remote pipe-end point (e.g. modem).
The implementation adds socket options at SOL_PNPIPE level:
PNPIPE_PIPE_HANDLE
It accepts an integer argument for setting value of pipe handle.
PNPIPE_ENABLE accepts one integer value (int). If set to zero, the pipe
is disabled. If the value is non-zero, the pipe is enabled. If the pipe
is not (yet) connected, ENOTCONN is error is returned.
The implementation also adds socket 'connect'. On calling the 'connect', pipe
will be created between the source socket and the destination, and the pipe
state will be set to PIPE_DISABLED.
After a pipe has been created and enabled successfully, the Pipe data can be
exchanged between the host-pep and remote-pep (modem).
User-space would typically follow below sequence with Pipe controller:-
-socket
-bind
-setsockopt for PNPIPE_PIPE_HANDLE
-connect
-setsockopt for PNPIPE_ENCAP_IP
-setsockopt for PNPIPE_ENABLE
