be2net: fix netdev_stats_update

Problem initially reproted and fixed by Eric Dumazet <eric.dumazet@gmail.com>

netdev_stats_update() resets netdev->stats and then accumulates stats from
various rings. This is wrong as stats readers can sometimes catch zero values.
Use temporary variables instead for accumulating per-ring values.

routine now uses a two-stage process that first ensures the message

This corrects a loophole that allowed a connection probe request to

Speeds up the creation of the FIN message that terminates a TIPC

rather than building all fields of the message from scratch. A FIN
message that is directed to the port itself is created the same way.
but also requires swapping the origin and destination address fields.

tipc: Partition name table instance array info into two parts

Modifies the name table array structure that contains the name
sequence instances for a given name type so that the publication
lists associated with a given instance are stored in a dynamically
allocated structure, rather than being embedded within the array
entry itself. This change is being done for several reasons:

1) It reduces the amount of data that needs to be copied whenever
a given array is expanded or contracted to accommodate the first
publication of a new name sequence or the removal of the last
publication of an existing name sequence.

2) It reduces the amount of memory associated with array entries that
are currently unused.

3) It facilitates the upcoming conversion of the publication lists
from TIPC-specific circular lists to standard kernel lists. (Standard
lists cannot be used with the former array structure because the
relocation of array entries during array expansion and contraction
would corrupt the lists.)

Note that, aside from introducing a small amount of code to dynamically
allocate and free the structure that now holds publication list info,
this change is largely a simple renaming exercise that replaces
references to "sseq->LIST" with "sseq->info->LIST" (or "info->LIST").

tipc: Optimizations & corrections to message rejection

Optimizes the creation of a returned payload message by duplicating
the original message and then updating the small number of fields
that need to be adjusted, rather than building the new message header
from scratch. In addition, certain operations that are not always
required are relocated so that they are only done if needed.

These optimizations also have the effect of addressing other issues
that were present previously:

1) Fixes a bug that caused the socket send routines to return the
size of the returned message, rather than the size of the sent
message, when a returnable payload message was sent to a non-existent
destination port.

2) The message header of the returned message now matches that of
the original message more closely. The header is now always the same
size as the original header, and some message header fields that
weren't being initialized in the returned message header are now
populated correctly -- namely the "d" and "s" bits, and the upper
bound of a multicast name instance (where present).

ixgbe: update perfect filter framework to support retaining filters

This change is meant to update the internal framework of ixgbe so that
perfect filters can be stored and tracked via software.

ixgbe: fix flags relating to perfect filters to support coexistence

I am removing the requirement that Ntuple filters have the same
number of queues and requirements as ATR.  As a result this change will
make it so that all the Ntuple flag does is disable ATR for now.

This change fixes an issue in which we were incorrectly re-enabling ATR
when we exited perfect filter mode.  This was due to the fact that the
logic assumed RSS and DCB were mutually exclusive which is no longer the
case.

To correct this we just need to add a check to guarantee DCB is disabled
before re-enabling ATR.

must be active before asserting carrier. It is similar to the Cisco
EtherChannel min-links feature. This allows setting the minimum number
of member ports that must be up (link-up state) before marking the

ssb: add __devinit to some functions

Two functions in ssb are using register_pci_controller() which is
__devinit. The functions ssb_pcicore_init_hostmode() and
ssb_gige_probe() should also be __devinit.

This fixes the following warning:
WARNING: vmlinux.o(.text+0x2727b8): Section mismatch in reference from the function ssb_pcicore_init_hostmode() to the function .devinit.text:register_pci_controller()

This is often because ssb_pcicore_init_hostmode lacks a __devinit

zd1211rw: detect stalled beacon interrupt faster

As USB_INT_ID_RETRY_FAILED can override USB_INT_ID_REGS, beacon interrupt
(CR_INTERRUPT) might be lost. Problem is that when device trigger CR_INTERRUPT
it disables HW interrupt. Now if USB_INT_ID_REGS with CR_INTERRUPT gets lost,
beacon interrupt stays disabled until beacon watchdog notices the stall. This
happen very often on heavy TX. Improve watchdog to trigger earlier, after three

zd1211rw: handle lost read-reg interrupts

Device losses read-reg interrupts. By looking at usbmon it appears that
USB_INT_ID_RETRY_FAILED can override USB_INT_ID_REGS. This causes read
command to timeout, usually under heavy TX.

Fix by retrying read registers again if USB_INT_ID_RETRY_FAILED is received
while waiting for USB_INT_ID_REGS.

However USB_INT_ID_REGS is not always lost but is received after
USB_INT_ID_RETRY_FAILED and is usually received by the retried read
command. USB_INT_ID_REGS of the retry is then left unhandled and might
be received by next read command. Handle this by ignoring previous
USB_INT_ID_REGS that doesn't match current read command request.
