This lets the SCSI stack retry the command when a SCSI command is
interrupted by a FireWire bus reset.Signed-off-by: Kristian Høgsberg
Signed-off-by: Stefan Richter -
This prevents superfluous bus traffic as fw-sbp2 logs in only to
get kicked off the device by another bus reset as the driver core
does bus management. Scheduling it this way lets the driver core
finish bus management before higher level drivers get the update
callback.Signed-off-by: Kristian Høgsberg

Sometimes we reconnect too soon, sometimes too late. Adding a retry
mechanism make the reconnect step much more robust.Signed-off-by: Kristian Høgsberg
Signed-off-by: Stefan Richter -
When a management ORB times out, either because the fw_transaction
times out or when we don't get the status write, we need to properly
cancel the entire operation.Signed-off-by: Kristian Høgsberg
Signed-off-by: Stefan Richter -
Drivers such as fw-sbp2 had no way to properly cancel in-progress
transactions, which could leave a pending transaction or an unset
packet in the low-level queues after kfree'ing the containing
structure. fw_cancel_transaction() lets drivers cancel a submitted
transaction.Signed-off-by: Kristian Høgsberg

The old DMA program for receiving async packets stops DMA while
processing received packets and only expects one packet per
interrupt. Stopping DMA can silently drop packets and we need to
handle multiple received packets per interrupt.This new version keeps DMA running at all times and just append new
pages as buffers fill up, and supports multiple packets per interrupt.Signed-off-by: Kristian Høgsberg

Copied from sbp2:
- enable spin-up by START STOP UNIT for all devices
- enable INQUIRY (36) workaround on demand
- prefer READ/ WRITE (10) over (6) for all devices
- prefer MODE SENSE (10) for MMC devicesSigned-off-by: Stefan Richter

Definitions as per IEEE 1212 and IEEE 1394:
Node ID: Concatenation of bus ID and local ID. 16 bits long.
Bus ID: Identifies a particular bus within a group of buses
interconnected by bus bridges.
Local ID: Identifies a particular node on a bus.
PHY ID: Local ID of IEEE 1394 nodes. 6 bits long.Never ever use a variable called node_id for anything else than a node ID.

This patch contains the following cleanups:
- "extern inline" -> "static inline"
- fw-topology.c: make struct fw_node_create staticSigned-off-by: Adrian Bunk

Instances of struct file_operations and struct fw_card_driver can be
qualified as "const". Ditto with struct fw_descriptor.data, struct
fw_device_id, and predefined instances of struct fw_address_region,
at least in the current implementation.Data qualified as const is placed into the .rodata section which won't
be mixed with dirty data.Signed-off-by: Stefan Richter
