61e115a56d [SSB]: add Sonics Silicon Backplane bus support
SSB is an SoC bus used in a number of embedded devices.  The most
well-known of these devices is probably the Linksys WRT54G, but there
are others as well.  The bus is also used internally on the BCM43xx
and BCM44xx devices from Broadcom.

This patch also includes support for SSB ID tables in modules, so
that SSB drivers can be loaded automatically.

768f3591e2 [NETNS]: Cleanup list walking in setup_net and cleanup_net
I proposed introducing a list_for_each_entry_continue_reverse macro
to be used in setup_net() when unrolling the failed ->init callback.

Here is the macro and some more cleanup in the setup_net() itself
to remove one variable from the stack :) The same thing is for the
cleanup_net() - the existing list_for_each_entry_reverse() is used.

Minor, but the code looks nicer.

4cd57c8078 [SCTP]: Enable the sending of the AUTH chunk.
SCTP-AUTH, Section 6.2:

   Endpoints MUST send all requested chunks authenticated where this has
   been requested by the peer.  The other chunks MAY be sent
   authenticated or not.  If endpoint pair shared keys are used, one of
   them MUST be selected for authentication.

   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.
   If there are multiple endpoint shared keys the sender selects one and
   uses the corresponding Shared Key Identifier

96793b4825 [IPV4]: Add ICMPMsgStats MIB (RFC 4293)
Background: RFC 4293 deprecates existing individual, named ICMP
type counters to be replaced with the ICMPMsgStatsTable. This table
includes entries for both IPv4 and IPv6, and requires counting of all
ICMP types, whether or not the machine implements the type.

These patches "remove" (but not really) the existing counters, and
replace them with the ICMPMsgStats tables for v4 and v6.
It includes the named counters in the /proc places they were, but gets the
values for them from the new tables. It also counts packets generated
from raw socket output (e.g., OutEchoes, MLD queries, RA's from
radvd, etc).

Changes:
1) create icmpmsg_statistics mib
2) create icmpv6msg_statistics mib
3) modify existing counters to use these
4) modify /proc/net/snmp to add "IcmpMsg" with all ICMP types
        listed by number for easy SNMP parsing
5) modify /proc/net/snmp printing for "Icmp" to get the named data
        from new counters.

It contains a list of chunks that a particular SCTP extension
uses.  Current extensions supported are Partial Reliability

When implementing new extensions (AUTH, PKT-DROP, etc..), new
chunks need to be added to this parameter.  Parameter processing
would be modified to negotiate support for these new features.

88d3aafdae [ETHTOOL] Provide default behaviors for a few ethtool sub-ioctls
For the operations
	get-tx-csum
	get-sg
	get-tso
	get-ufo
the default ethtool_op_xxx behavior is fine for all drivers, so we
permit op==NULL to imply the default behavior.

This provides a more uniform behavior across all drivers, eliminating
ethtool(8) "ioctl not supported" errors on older drivers that had
not been updated for the latest sub-ioctls.

The ethtool_op_xxx() functions are left exported, in case anyone
wishes to call them directly from a driver-private implementation --
a not-uncommon case.  Should an ethtool_op_xxx() helper remain unused
for a while, except by net/core/ethtool.c, we can un-export it at a
later date.

- Reduced from 3 to 1 if condition before check for processing packet receive

- Implemented Jeff's comment to use synchronize_irq. Removed the isr_cnt
  variable as it became redundant.
- One time de assert the interrupts by writing all F's to the general_int_mask
  register instead of de asserting by clearing the source of interrupts with
  multiple writes which causes loss of interrupts (race conditions). It is
  entirely possible that before the driver has a chance to mask the asserted
  alarm bit, another alarm/traffic interrupt bit gets asserted as well. In
  this case Herc will keep the INTA line asserted and the bridge will not
  send a new Assert_INTA message upstream.

8116f3cf4a [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.

[ Fix warnings wrt. do_s2io_chk_alarm_bit(), Callers pass in an
  "unsigned long long *" but the function takes a "u64 *" which is
  different on many 64-bit platforms. -DaveM ]

9caab4587b 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.

bb9366af7b cxgb3 - CQ context operations time out too soon.
Currently, the driver only tries up to 5 times (5us) to get the results
of a CQ context operation.  Testing has shown the chip can take as much
as 50us to return the response on SG_CONTEXT_CMD operations.  So we up
the retry count to 100 to cover high loads.
