Lars-Peter Clausen 0caa1ef0cb sr: fx2lafw: Abort pending transfers when sampling is stopped 
The recent reworks of the fx2lafw made sure that the total buffer size is large
enough hold 500ms of data. This was done to improve performance and stability.
That the timeout value for a transfer was also increased to over 500ms, a side
effect of this is that when sampling is stopped there will be a additional delay
of 500ms. This is because the driver waits for all transfers to be freed
before it sends a SR_DF_END packet. Once sampling has stopped this will only
happen once a transfer times out. This patch cancels all pending transfers when
sampling is stopped, this will cause them to be freed almost immediately and the
additional delay will disappear.

Also make sure, that if we know, that we just have received the last transfer to
not resubmit this transfer again.

README 

-------------------------------------------------------------------------------
README
-------------------------------------------------------------------------------

The sigrok project aims at creating a portable, cross-platform,
Free/Libre/Open-Source logic analyzer software that supports various
logic analyzer hardware products.

libsigrok is a shared library written in C which provides the basic API
for talking to logic analyzer hardware and reading/writing the acquired data
into various input/output file formats.


Requirements
------------

 - git
 - gcc (>= 4.0)
 - make
 - autoconf >= 2.63
 - automake >= 1.11
 - libtool
 - pkg-config >= 0.22
 - libglib >= 2.28.0
 - libusb >= 1.0.5 (for most logic analyzer hardware)
 - libzip >= 0.8
 - libftdi >= 0.16 (for some logic analyzer hardware)
 - libudev >= 151 (for some logic analyzer hardware)


Building and installing
-----------------------

In order to get the libsigrok source code and build it, run:

 $ git clone git://sigrok.git.sourceforge.net/gitroot/sigrok/sigrok
 $ cd sigrok/libsigrok
 $ ./autogen.sh
 $ ./configure
 $ make

For installing libsigrok:

 $ make install

Please see the following wiki pages for more detailed instructions:

 http://sigrok.org/wiki/Linux
 http://sigrok.org/wiki/Mac_OS_X
 http://sigrok.org/wiki/Windows
 http://sigrok.org/wiki/FreeBSD


Firmware
--------

Some devices supported by libsigrok need a firmware to be uploaded before the
device can be used. 

The default location where libsigrok expects the firmware files is:

  $prefix/share/sigrok-firmware

($prefix is usually /usr/local or /usr, depending on your ./configure options)

For further information see:

  http://sigrok.org/wiki/Firmware


Mailing lists
-------------

There are two mailing lists for sigrok/libsigrok:

 https://lists.sourceforge.net/lists/listinfo/sigrok-devel
 https://lists.sourceforge.net/lists/listinfo/sigrok-commits


IRC
---

You can find the sigrok developers in the #sigrok IRC channel on Freenode.
