When final timer expires, it might also mean that the i:cmd wasn't
received properly. If we have rejected frames, we can try to resend them.

[-- Attachment #1: irda_input_validation.patch --]
[-- Type: text/plain, Size: 2450 bytes --]
From: Robie Basak <rb-oss-1@justgohome.co.uk>
When using a stir4200-based USB adaptor to talk to a device that uses an
mcp2150, the stir4200 sometimes drops an incoming frame causing the
mcp2150 to try and retransmit the lost frame. In this combination, the
next frame received from the mcp2150 is often invalid - either an empty
i:rsp or an IrCOMM i:rsp with an invalid clen. These corner cases are
now checked.

- * Belkin is selling a dongle called the SmartBeam.

- * the same name and looking the exactly same (grrr...).
- * I guess that I've got the old one, because inside I don't have
- * a jumper for IrDA/ASK...
- *
- * As far as I can make it from info on their web site, the old dongle
- * support only 9600 b/s, which make our life much simpler as far as
- * the driver is concerned, but you might not like it very much ;-)
- * The new SmartBeam does 115 kb/s, and I've not tested it...
- *
- * Belkin claim that the correct driver for the old dongle (in Windows)
- * is the generic Parallax 9500a driver, but the Linux LiteLink driver
- * fails for me (probably because Linux-IrDA doesn't rate fallback),
- * so I created this really dumb driver...
- *
- * In fact, this driver doesn't do much. The only thing it does is to
- * prevent Linux-IrDA to use any other speed than 9600 b/s ;-) This
- * driver is called "old_belkin" so that when the new SmartBeam is supported
- * its driver can be called "belkin" instead of "new_belkin".
- *
- * Note : this driver was written without any info/help from Belkin,
- * so a lot of info here might be totally wrong. Blame me ;-)

> Here goes a batch of 4 IrDA patches against your latest net-2.6.25 tree.
All 4 patches applied, thanks Sam.
You might want to consider submitting those first two
patches for 2.6.24 as they look like pure fixes.
