Linux-2.6.12-rc2v2.6.12-rc2
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

8 select CRC_CCITT
9 ---help---
10 Say Y here if you want to build support for the IrDA (TM) protocols.
11 The Infrared Data Associations (tm) specifies standards for wireless
12 infrared communication and is supported by most laptops and PDA's.
13
14 To use Linux support for the IrDA (tm) protocols, you will also need
15 some user-space utilities like irattach. For more information, see
16 the file <file:Documentation/networking/irda.txt>. You also want to
17 read the IR-HOWTO, available at
18 <http://www.tldp.org/docs.html#howto>.
19
20 If you want to exchange bits of data (vCal, vCard) with a PDA, you
21 will need to install some OBEX application, such as OpenObex :
22 <http://sourceforge.net/projects/openobex/>
23
24 To compile this support as a module, choose M here: the module will
25 be called irda.

39 help
40 Say Y here to support the connectionless Ultra IRDA protocol.
41 Ultra allows to exchange data over IrDA with really simple devices
42 (watch, beacon) without the overhead of the IrDA protocol (no handshaking,
43 no management frames, simple fixed header).
44 Ultra is available as a special socket : socket(AF_IRDA, SOCK_DGRAM, 1);

49config IRDA_CACHE_LAST_LSAP
50 bool "Cache last LSAP"
51 depends on IRDA
52 help
53 Say Y here if you want IrLMP to cache the last LSAP used. This
54 makes sense since most frames will be sent/received on the same
55 connection. Enabling this option will save a hash-lookup per frame.
56
57 If unsure, say Y.
58
59config IRDA_FAST_RR
60 bool "Fast RRs (low latency)"
61 depends on IRDA
62 ---help---
63 Say Y here is you want IrLAP to send fast RR (Receive Ready) frames
64 when acting as a primary station.
65 Disabling this option will make latency over IrDA very bad. Enabling
66 this option will make the IrDA stack send more packet than strictly
67 necessary, thus reduce your battery life (but not that much).
68
69 Fast RR will make IrLAP send out a RR frame immediately when
70 receiving a frame if its own transmit queue is currently empty. This
71 will give a lot of speed improvement when receiving much data since
72 the secondary station will not have to wait the max. turn around
73 time (usually 500ms) before it is allowed to transmit the next time.
74 If the transmit queue of the secondary is also empty, the primary will
75 start backing-off before sending another RR frame, waiting longer
76 each time until the back-off reaches the max. turn around time.
77 This back-off increase in controlled via
78 /proc/sys/net/irda/fast_poll_increase
79
80 If unsure, say Y.
81
82config IRDA_DEBUG
83 bool "Debug information"
84 depends on IRDA
85 help
86 Say Y here if you want the IrDA subsystem to write debug information
87 to your syslog. You can change the debug level in
88 /proc/sys/net/irda/debug .
89 When this option is enabled, the IrDA also perform many extra internal
90 verifications which will usually prevent the kernel to crash in case of
91 bugs.
92
93 If unsure, say Y (since it makes it easier to find the bugs).
