SSB is an SoC bus used in a number of embedded devices.  The most

are others as well.  The bus is also used internally on the BCM43xx

   authenticated or not.  If endpoint pair shared keys are used, one of

   To send chunks in an authenticated way, the sender MUST include these
   chunks after an AUTH chunk.  This means that a sender MUST bundle
   chunks in order to authenticate them.

   If the endpoint has no endpoint pair shared key for the peer, it MUST
   use Shared Key Identifier 0 with an empty endpoint pair shared key.

Sivakumar Subramani [Mon, 17 Sep 2007 20:05:35 +0000]
[S2IO]: Handle and monitor all of the device errors and alarms

- Added support to poll entire set of device errors and alarams.
- A note on how device errors and alarms are handled:
- The adapter will automatically recover from uncorrectable ECC errors.
  Packets containing corrupted data will be dropped (not transmitted) or tagged
  as invalid before being passed to the host.
- The adapter cannot recover from any internal state machine errors. A state
  machine error requires a device reset.
- Any internal error that could potentially result in .store trampling.
  (undesirable PCI behaviour)is tagged as a "serious error". In such cases
  the adapter will give up its ability to be a bus master. In this situation
  the host will still be able to read internal device registers in order to
  generate an error report. A device reset is necessary to return to normal
  operation.
- In the event of a pcix data parity error, the adapter will automatically
  disable itself. Adapter_En will automatically transition from '1' to '0' and
  the adapter will enter its clean-up routine. Once the device has achieved
  quiescence, an adapter reset should be performed.
- Replaced alarm_intr_handler() with s2io_handle_errors().
- Added statistic counters to monitor the alarms.

Sivakumar Subramani [Thu, 6 Sep 2007 10:21:54 +0000]
S2io: Enable all the error and alarm indications

- Added support to unmask entire set of device errors and alarams.
        Alarm interrupts are generated for a myriad of purposes, ranging from
  illegal operations or requests to internal state machine errors and
  uncorrectable data corruption errors. In several cases the adapter can
  recover gracefully from unexpected events; however, in some cases, a device
  reset may be necessary. This patch handles alarms generated by all the
  blocks within the device.

  The adapter generates the following types of alarms:
        1. Link state transitions (local/remote fault) or other link-related
           problems.
        2. Problems with any device peripherals, including the EEPROM, FLASH,
           etc.
        3. Correctable ECC errors (single-bit errors) on internal data
           structures or frame data.
        4. Uncorrectable ECC errors (multi-bit errors) on internal data
           structures or frame data.
        5. State machine errors, which indicate that internal control
           structures have become corrupted.
        6. PCI related errors, including parity errors or illegal transactions.
        7. Other unexpected events.

- Implemented Jeff's review comments to use do_s2io_write_bits function to avoid
  duplicate codes.

This patch adds support for the Intel 82598 PCI-Express 10GbE
chipset. Devices will be available on the market soon.

This version of the driver is largely the same as the last release:

  * Driver uses a single RX and single TX queue, each using 1 MSI-X
  irq vector.
  * Driver runs in NAPI mode only
  * Driver is largely multiqueue-ready (TM)

Changes since 20070803:
  * removed wrappers for hardware functions
  * incorporated e1000e-style HW api reorganization code
  * sparse/checkpatch cleanups, namespace cleanups
  * driver prints out extra debugging information at load time
    identifying adapter board number, mac, phy types
  * removed ixgbe_api.c, ixgbe_api.h, ixgbe_osdep.h
  * driver update to 1.1.18
  * removed ixgbe.txt which contained no useful info anymore

Masakazu Mokuno [Fri, 31 Aug 2007 13:22:32 +0000]
PS3: changed the way to handle tx skbs

The PS3 virtual network device requires a vlan tag in the sending packet
to select the destination device, ethernet port or wireless.
As the vlan tag field is in the middle of the passed data,
we should insert it into the packet data.
To avoid copying much of the packet data, the driver used two tx descriptors
for one tx skb; one descriptor was for sending a small static
buffer which contained vlan tag and copied header (two mac addresses),
one was for the residual data after the vlan field.

This patch changes the way to insert the vlan tag.  By changing
netdev->hard_header_len, we can make the headroom for moving mac address
fields in the skb buffer. Then we can send one tx skb with
one tx descriptor.  This also gives us a tx throughut gain of approx.
20% according to netperf results.

Unfortunately there's no timeout for how long a packet can sit on
the TX ring after completion before an interrupt is generated, and
we want to have a threshold that's larger than one packet per interrupt.

So we have to have a timer that occasionally cleans the TX ring even
though there hasn't been an interrupt. Instead of setting up a dedicated
timer for this, just clean it in the NAPI poll routine instead.

This driver implements support for the ICH9 on-board LAN ethernet

The driver encompasses code to support 82571/2/3, es2lan and ICH8
devices as well, but those device IDs are disabled and will be
"lifted" from the e1000 driver over one at a time once this driver
receives some more live time.

Dan Williams [Mon, 20 Aug 2007 15:43:25 +0000]
[PATCH] libertas: reorganize and simplify init sequence

This patch moves all firmware load responsibility into the interface-specific
code and gets rid of the firmware pointer in the generic card structure.  It
also removes 3 fairly unecessary callbacks: hw_register_dev, hw_unregister_dev,
and hw_prog_firmware.  It also makes the init sequence from interface
probe functions more logical, as there are paired add/remove and start/stop
calls into generic libertas code.

Because the USB driver code uses the same TX URB callback for both firmware
upload (where the generic libertas structure isn't initialized yet) and for
normal operation (where it is), some bits of USB code have to deal with
'priv' being NULL.  All USB firmware upload bits have been changed to not
require 'priv' at all, but simply the USB card structure.
