-   Instructions for use
-   --------------------
+   For usage instructions, please refer to:
 
-   1) Map a Linux block device to an existing rbd image.
-
-      Usage: <mon ip addr> <options> <pool name> <rbd image name> [snap name]
-
-      $ echo "192.168.0.1 name=admin rbd foo" > /sys/class/rbd/add
-
-      The snapshot name can be "-" or omitted to map the image read/write.
-
-   2) List all active blkdev<->object mappings.
-
-      In this example, we have performed step #1 twice, creating two blkdevs,
-      mapped to two separate rados objects in the rados rbd pool
-
-      $ cat /sys/class/rbd/list
-      #id     major   client_name     pool    name    snap    KB
-      0       254     client4143      rbd     foo     -      1024000
-
-      The columns, in order, are:
-      - blkdev unique id
-      - blkdev assigned major
-      - rados client id
-      - rados pool name
-      - rados block device name
-      - mapped snapshot ("-" if none)
-      - device size in KB
-
-
-   3) Create a snapshot.
-
-      Usage: <blkdev id> <snapname>
-
-      $ echo "0 mysnap" > /sys/class/rbd/snap_create
-
-
-   4) Listing a snapshot.
-
-      $ cat /sys/class/rbd/snaps_list
-      #id     snap    KB
-      0       -       1024000 (*)
-      0       foo     1024000
-
-      The columns, in order, are:
-      - blkdev unique id
-      - snapshot name, '-' means none (active read/write version)
-      - size of device at time of snapshot
-      - the (*) indicates this is the active version
-
-   5) Rollback to snapshot.
-
-      Usage: <blkdev id> <snapname>
-
-      $ echo "0 mysnap" > /sys/class/rbd/snap_rollback
-
-
-   6) Mapping an image using snapshot.
-
-      A snapshot mapping is read-only. This is being done by passing
-      snap=<snapname> to the options when adding a device.
-
-      $ echo "192.168.0.1 name=admin,snap=mysnap rbd foo" > /sys/class/rbd/add
-
-
-   7) Remove an active blkdev<->rbd image mapping.
-
-      In this example, we remove the mapping with blkdev unique id 1.
-
-      $ echo 1 > /sys/class/rbd/remove
-
-
-   NOTE:  The actual creation and deletion of rados objects is outside the scope
-   of this driver.

+                 * Both variants suffer from the same problem: if the driver
+                 * sleeps, then it blocks all ioctls since the lock is still
+                 * held. This is very common for VIDIOC_DQBUF since that
+                 * normally waits for a frame to arrive. As a result any other

+                 * should take 0.01s may now take 10-20 seconds.

+ * First, "tile_net_init_module()" initializes all four "devices" which
+ * can be used by linux.
+ *
+ * Then, "ifconfig DEVICE up" calls "tile_net_open()", which analyzes
+ * the network cpus, then uses "tile_net_open_aux()" to initialize
+ * LIPP/LEPP, and then uses "tile_net_open_inner()" to register all
+ * the tiles, provide buffers to LIPP, allow ingress to start, and
+ * turn on hypervisor interrupt handling (and NAPI) on all tiles.
+ *
+ * If registration fails due to the link being down, then "retry_work"
+ * is used to keep calling "tile_net_open_inner()" until it succeeds.
+ *
+ * If "ifconfig DEVICE down" is called, it uses "tile_net_stop()" to
+ * stop egress, drain the LIPP buffers, unregister all the tiles, stop
+ * LIPP/LEPP, and wipe the LEPP queue.
+ *
+ * We start out with the ingress interrupt enabled on each CPU.  When
+ * this interrupt fires, we disable it, and call "napi_schedule()".
+ * This will cause "tile_net_poll()" to be called, which will pull
+ * packets from the netio queue, filtering them out, or passing them
+ * to "netif_receive_skb()".  If our budget is exhausted, we will
+ * return, knowing we will be called again later.  Otherwise, we
+ * reenable the ingress interrupt, and call "napi_complete()".
+ *
+ *
+ * NOTE: The use of "native_driver" ensures that EPP exists, and that
+ * "epp_sendv" is legal, and that "LIPP" is being used.
+ *
+ * NOTE: Failing to free completions for an arbitrarily long time
+ * (which is defined to be illegal) does in fact cause bizarre
+ * problems.  The "egress_timer" helps prevent this from happening.
