b0c1e928c8 tipc: Remove user registry subsystem
Eliminates routines, data structures, and files that make up TIPC's
user registry. The user registry is no longer needed since the native
API routines that utilized it no longer exist and there are no longer
any internal TIPC services that use it.

aa70200e00 tipc: Eliminate use of user registry by topology service
Simplifies TIPC's network topology service so that it no longer registers
its ports with the user registry, since the service doesn't take advantage
of any of the registry's capabilities.

8f92df6ad4 tipc: Remove prototype code for supporting multiple clusters
Eliminates routines, data structures, and files that were intended
to allow TIPC to support a network containing multiple clusters.
Currently, TIPC supports only networks consisting of a single cluster
within a single zone, so this code is unnecessary.

08c80e9a03 tipc: Remove prototype code for supporting slave nodes
Simplifies routines and data structures that were intended to allow
TIPC to support slave nodes (i.e. nodes that did not have links to
all of the other nodes in its cluster, forcing TIPC to route messages
that it could not deliver directly through a non-slave node).

Currently, TIPC supports only networks containing non-slave nodes,
so this code is unnecessary.

Note: The latest edition of the TIPC 2.0 Specification has eliminated
the concept of slave nodes entirely.

slot_dequeue_head() should make sure slot skb chain is correct in both

instead each time a flow is setup.

eeaeb068f1 sch_sfq: allow big packets and be fair
SFQ is currently 'limited' to small packets, because it uses a 15bit
allotment number per flow. Introduce a scale by 8, so that we can handle
full size TSO/GRO packets.

Use appropriate handling to make sure allot is positive before a new
packet is dequeued, so that fairness is respected.

0f333d10e3 sky2: Do not use legacy PCI power management
The sky2 driver uses the legacy PCI power management, so it has to do
some PCI-specific things in its ->suspend() and ->resume() callbacks,
which isn't necessary and should better be done by the PCI
sybsystem-level power management code.  Moreover, it uses
device_set_wakeup_enable() incorrectly (that function should be
used when the WoL setting is changed rather than during suspend).

Convert sky2 to the new PCI power management framework and make it
let the PCI subsystem take care of all the PCI-specific aspects of
device handling during system power transitions.

Tested on a desktop machine with a Marvell 88E8056 PCI-E adapter.

a29ba9d2d8 bnx2: Free IRQ before freeing status block memory
When changing ring size, we free all memory including status block
memory.  If we're in INTA mode and sharing IRQ, the IRQ handler can
be called and it will reference the NULL status block pointer.

Because of the lockless design of the IRQ handler, there is no simple
way to synchronize and prevent this.  So we avoid this problem by
freeing the IRQ handler before freeing the status block memory.

can use the dcbnl_ops routines if additional handling is

3e29027af4 dcbnl: add support for ieee8021Qaz attributes
The IEEE8021Qaz is the IEEE standard version of CEE. The
standard has had enough significant changes from the CEE
version that many of the CEE attributes have no meaning
in the new spec or do not easily map to IEEE standards.

Rather then attempt to create a complicated mapping
between CEE and IEEE standards this patch adds a nested
IEEE attribute to the list of DCB attributes. The policy
is,

	[DCB_ATTR_IFNAME]
	[DCB_ATTR_STATE]
	...
	[DCB_ATTR_IEEE]
		[DCB_ATTR_IEEE_ETS]
		[DCB_ATTR_IEEE_PFC]
		[DCB_ATTR_IEEE_APP_TABLE]
			[DCB_ATTR_IEEE_APP]
			...

The following dcbnl_rtnl_ops routines were added to handle
the IEEE standard,

	int (*ieee_getets) (struct net_device *, struct ieee_ets *);
	int (*ieee_setets) (struct net_device *, struct ieee_ets *);
	int (*ieee_getpfc) (struct net_device *, struct ieee_pfc *);
	int (*ieee_setpfc) (struct net_device *, struct ieee_pfc *);
	int (*ieee_getapp) (struct net_device *, struct dcb_app *);
	int (*ieee_setapp) (struct net_device *, struct dcb_app *);

be7fa3263a bna: TxRx and datapath fix
Change Details:
	- Check HW ready condition before accessing h/w register in data-path
	- Postpone clean-up of data buffers to the data-path restart path and
	wait in the cleanup routines for in-flight DMA to complete
	- Separate out Tx completion processing from Rx poll routine

2316aa2aee ixgbevf: Add X540 VF device support to the ixgbevf driver
The X540 introduces a new Virtual Function device ID so that the X540
VF device can be distinguished from the 82599 VF device.  The X540 VF
device will have additional capability over the 82599 VF device so it
is necessary to be able to discern the difference.

a985b6c31f ixgbe: Add anti-spoofing feature support
Add support for the anti-spoofing feature in the HW.  Packets from
VF devices with spoofed MAC addresses or VLAN tags will be blocked
and a counter incremented.  During the watchdog timer the spoofed
packet dropped counter is read and if it is non-zero then a warning
message is displayed on the host VMM's console.

0e512bfc2c igbvf: force link checking when mailbox timeout has occurred
This change forces the link down when a mailbox timeout has occurred.
Previously it was possible for a mailbox timeout to occur but for the
interface to stay up.  The problem with this was that it became possible
for an interface to stay up and miss multiple requests resulting in a
possible issue since the interface will be running in an unknown state.

Add support for the anti-spoofing feature in the HW.  Packets from
VF devices with spoofed MAC addresses or VLAN tags will be blocked
and an event generated.  When the watchdog task runs it will call a
function to check if any spoof events occurred.  If an event was
detected then a warning message is dumped to the system log.

Gasparakis, Joseph
1b5dda331f igb: Some fine tuning
This patch does the following:

1. Changes the existing supported device id's so now DH89xxCC is not supported when EEPROM is not read.
2. Adds two more device ids for DH89xxCC in backplane mode and SFP.
3. Driver now initializes previously possibly uninitialized value in igb_reset_mdicnfg_82580().
