+What: dv1394 (a.k.a. "OHCI-DV I/O support" for FireWire)
+Contact: linux1394-devel@lists.sourceforge.net
+Description:
+ New application development should use raw1394 + userspace libraries
+ instead, notably libiec61883 which is functionally equivalent.
+
+Users:
+ ffmpeg/libavformat (used by a variety of media players)
+ dvgrab v1.x (replaced by dvgrab2 on top of raw1394 and resp. libraries)

-What: dv1394 driver (CONFIG_IEEE1394_DV1394)
-When: June 2007
-Why: Replaced by raw1394 + userspace libraries, notably libiec61883. This
- shift of application support has been indicated on www.linux1394.org
- and developers' mailinglists for quite some time. Major applications
- have been converted, with the exception of ffmpeg and hence xine.
- Piped output of dvgrab2 is a partial equivalent to dv1394.

The return value is zero for success, else a negative errno. It should
be checked, since the get/set calls don't have error returns and since
misconfiguration is possible. (These calls could sleep.)
+For output GPIOs, the value provided becomes the initial output value.
+This helps avoid signal glitching during system startup.
+
Setting the direction can fail if the GPIO number is invalid, or when
that particular GPIO can't be used in that mode. It's generally a bad
idea to rely on boot firmware to have set the direction correctly, since

Fix hang (in i_size_read) when simultaneous size update of same remote file
on smp system corrupts sequence number. Do not reread unnecessarily partial page
(which we are about to overwrite anyway) when writing out file opened rw.
+When DOS attribute of file on non-Unix server's file changes on the server side
+from read-only back to read-write, reflect this change in default file mode
+(we had been leaving a file's mode read-only until the inode were reloaded).
+Allow setting of attribute back to ATTR_NORMAL (removing readonly dos attribute
+when archive dos attribute not set and we are changing mode back to writeable
+on server which does not support the Unix Extensions).
Version 1.47

The Packet Layer Protocol (PLP) is a way to route packets over X.25
connections in general and amateur radio AX.25 connections in
particular, essentially an alternative to NET/ROM.
A comprehensive listing of all the software for Linux amateur radio
users as well as information about how to configure an AX.25 port is

-/* SECURE SOCKET IMPLEMENTATION
- *
- * TRANSMIT:
- *
- * When the user sends a packet via send() system call
- * the wanpipe_sendmsg() function is executed.
- *
- * Each packet is enqueud into sk->sk_write_queue transmit
- * queue. When the packet is enqueued, a delayed transmit
- * timer is triggerd which acts as a Bottom Half hander.
- *
- * wanpipe_delay_transmit() function (BH), dequeues packets
- * from the sk->sk_write_queue transmit queue and sends it
- * to the deriver via dev->hard_start_xmit(skb, dev) function.
- * Note, this function is actual a function pointer of if_send()
- * routine in the wanpipe driver.
- *
- * X25API GUARANTEED DELIVERY:
- *
- * In order to provide 100% guaranteed packet delivery,
- * an atomic 'packet_sent' counter is implemented. Counter
- * is incremented for each packet enqueued
- * into sk->sk_write_queue. Counter is decremented each
- * time wanpipe_delayed_transmit() function successfuly
- * passes the packet to the driver. Before each send(), a poll
- * routine checks the sock resources The maximum value of
- * packet sent counter is 1, thus if one packet is queued, the
- * application will block until that packet is passed to the
- * driver.
- *
- * RECEIVE:
- *
- * Wanpipe device drivers call the socket bottom half
- * function, wanpipe_rcv() to queue the incoming packets
- * into an AF_WANPIPE socket queue. Based on wanpipe_rcv()
- * return code, the driver knows whether the packet was
- * successfully queued. If the socket queue is full,
- * protocol flow control is used by the driver, if any,
- * to slow down the traffic until the sock queue is free.
- *
- * Every time a packet arrives into a socket queue the
- * socket wakes up processes which are waiting to receive
- * data.
- *
- * If the socket queue is full, the driver sets a block
- * bit which signals the socket to kick the wanpipe driver
- * bottom half hander when the socket queue is partialy
- * empty. wanpipe_recvmsg() function performs this action.
- *
- * In case of x25api, packets will never be dropped, since
- * flow control is available.
- *
- * In case of streaming protocols like CHDLC, packets will
- * be dropped but the statistics will be generated.
