The current logic suffers from a slow response time to disable user DB
usage, and also fails to avoid DB FIFO drops under heavy load. This commit
fixes these deficiencies and makes the avoidance logic more optimal.
This is done by more efficiently notifying the ULDs of potential DB
problems, and implements a smoother flow control algorithm in iw_cxgb4,
which is the ULD that puts the most load on the DB fifo.

Design:

cxgb4:

Direct ULD callback from the DB FULL/DROP interrupt handler.  This allows
the ULD to stop doing user DB writes as quickly as possible.

While user DB usage is disabled, the LLD will accumulate DB write events
for its queues.  Then once DB usage is reenabled, a single DB write is
done for each queue with its accumulated write count.  This reduces the
load put on the DB fifo when reenabling.

iw_cxgb4:

Instead of marking each qp to indicate DB writes are disabled, we create
a device-global status page that each user process maps.  This allows
iw_cxgb4 to only set this single bit to disable all DB writes for all
user QPs vs traversing the idr of all the active QPs.  If the libcxgb4
doesn't support this, then we fall back to the old approach of marking
each QP.  Thus we allow the new driver to work with an older libcxgb4.

When the LLD upcalls iw_cxgb4 indicating DB FULL, we disable all DB writes
via the status page and transition the DB state to STOPPED.  As user
processes see that DB writes are disabled, they call into iw_cxgb4
to submit their DB write events.  Since the DB state is in STOPPED,
the QP trying to write gets enqueued on a new DB "flow control" list.
As subsequent DB writes are submitted for this flow controlled QP, the
amount of writes are accumulated for each QP on the flow control list.
So all the user QPs that are actively ringing the DB get put on this
list and the number of writes they request are accumulated.

When the LLD upcalls iw_cxgb4 indicating DB EMPTY, which is in a workq
context, we change the DB state to FLOW_CONTROL, and begin resuming all
the QPs that are on the flow control list.  This logic runs on until
the flow control list is empty or we exit FLOW_CONTROL mode (due to
a DB DROP upcall, for example).  QPs are removed from this list, and
their accumulated DB write counts written to the DB FIFO.  Sets of QPs,
called chunks in the code, are removed at one time. The chunk size is 64.
So 64 QPs are resumed at a time, and before the next chunk is resumed, the
logic waits (blocks) for the DB FIFO to drain.  This prevents resuming to
quickly and overflowing the FIFO.  Once the flow control list is empty,
the db state transitions back to NORMAL and user QPs are again allowed
to write directly to the user DB register.

The algorithm is designed such that if the DB write load is high enough,
then all the DB writes get submitted by the kernel using this flow
controlled approach to avoid DB drops.  As the load lightens though, we
resume to normal DB writes directly by user applications.

We can't remove it because legacy, so add a new type which corresponds to

Intel Wired LAN Driver Updates

This series contains updates to igb, i40e and i40evf.

I provide a code comment fix which David Miller noticed in the last
series of patches I submitted.

Shannon provides a patch to cleanup the NAPI structs when deleting the
netdev.

Anjali provides several patches for i40e, first fixes a bug in the update
filter logic which was causing a kernel panic.  Then provides a fix to
rename an error bit to correctly indicate the error.  Adds a definition
for a new state variable to keep track of features automatically disabled
due to hardware resource limitations versus user enforced feature disabled.
Anjali provides a patch to add code to handle when there is a filter
programming error due to a full table, which also resolves a previous
compile warning about an unused "*pf" variable introduced in the last i40e
series patch submission.

Jesse provides three i40e patches to cleanup strings to make more
consistent and to align with other Intel drivers.

Akeem cleans up a misleading function header comment for i40e.

Mitch provides a fix for i40e/i40evf to use the correctly reported number
of MSI-X vectors in the PF an VF.  Then provides a patch to use
dma_set_mask_and_coherent() which was introduced in v3.13 and simplifies
the DMA mapping code a bit.

v2:
- dropped the 2 ixgbe patches from Emil based on feedback from David Miller,
  where the 2 fixes should be handled in the net core to fix all drivers

ieee802154: fix endianness and header handling

This patch set enforces network byte order on all internal operations and
fields of the 802.15.4 stack and adds a general representation of 802.15.4
headers with operations to create and parse those headers. This reduces code
duplication in the current stack and also allows for upper layers to read
headers of packets they have just received; it is also necessary for 802.15.4
link layer security, which requires header mangling.

Changes since v1:
 * fixed lowpan packet rx after reassembly. Control blocks were used to
   retrieve source/dest addresses, but the CB is clobbered by reassembly.

 "Three of these are regression fixes, for two recent regressions and
  one introduced during the 3.13 cycle, and the fourth one is a working
  version of the fix that had to be reverted last time.

  Specifics:

   - A recent ACPI resources handling fix overlooked the fact that it
     had to update the ACPI PNP subsystem's resources parsing too and
     caused confusing warning messages to be printed during system
     intialization on some systems (with arguably buggy ACPI tables).
     Fix from Zhang Rui.

   - Moving the early ACPI initialization before timekeeping_init()
     earlier in this cycle broke fast TSC calibration on at least one
     system, so it needs to be done later, but still before
     efi_enter_virtual_mode() to allow the EFI initialization to refer
     to ACPI.

   - A change related to code duplication reduction in the cpufreq core
     inadvertently caused cpufreq intialization to fail for some CPUs
     handled by intel_pstate by adding checks that may fail for that
     driver, but aren't even necessary when it is used.  The issue is
     addressed by preventing those checks from run in the configurations
     in which they aren't needed.

   - If the Hardware Reduced ACPI flag is set in the ACPI tables, system
     suspend, hibernation and ACPI power off will only work when special
     sleep control and sleep status registeres are provided (their
     addresses in the ACPI tables are not zero).  If those registers are
     not available, the features in question have no chances to work, so
     they shouldn't even be regarded as supported.  That helps with
     power off in particular, because alternative power off methods may
     be used then and they may actually work"

  13) Forced eviction in inet_frag_evictor() must strictly make sure all
      frags are deleted, otherwise module unload (f.e.  6lowpan) can
      crash.  Fix from Florian Westphal.

  14) Remove assumptions in AF_UNIX's use of csum_partial() (which it
      uses as a hash function), which breaks on PowerPC.  From Anton
      Blanchard.

      The main gist of the issue is that csum_partial() is defined only
      as a value that, once folded (f.e.  via csum_fold()) produces a
      correct 16-bit checksum.  It is legitimate, therefore, for
      csum_partial() to produce two different 32-bit values over the
      same data if their respective alignments are different.

  15) Fix endiannes bug in MAC address handling of ibmveth driver, also
      from Anton Blanchard.

  16) Error checks for ipv6 exthdrs offload registration are reversed,
      from Anton Nayshtut.

  17) Externally triggered ipv6 addrconf routes should count against the
      garbage collection threshold.  Fix from Sabrina Dubroca.

  18) The PCI shutdown handler added to the bnx2 driver can wedge the
      chip if it was not brought up earlier already, which in particular
      causes the firmware to shut down the PHY.  Fix from Michael Chan.

  19) Adjust the sanity WARN_ON_ONCE() in qdisc_list_add() because as
      currently coded it can and does trigger in legitimate situations.
      From Eric Dumazet.

  20) BNA driver fails to build on ARM because of a too large udelay()
      call, fix from Ben Hutchings.

  21) Fair-Queue qdisc holds locks during GFP_KERNEL allocations, fix
      from Eric Dumazet.

  22) The vlan passthrough ops added in the previous release causes a
      regression in source MAC address setting of outgoing headers in
      some circumstances.  Fix from Peter Boström"
