staging: octeon: Fix logic for waking octeon ethernet tx queue.

Only wake tx queue when driver queue is back within bounds.

The logic here was just reenabling the queue when any buffers had been
freed.  the queue was stopped whenever the length exceeded 1000
(MAX_OUT_QUEUE_DEPTH), but then was essentially immediately started again.
On a congested link, the queue length would just keep increasing up to
around 8000 (for average size packets), at which point the hardware would
start refusing the packets and they would begin to be dropped.
This prevented the qdisc layer from effectively managing and prioritising
packets, as essentially all packets were being allowed into the driver
queue and then were being dropped by the hardware.

This change only restarts the queue if the length is less than 1000
(MAX_OUT_QUEUE_DEPTH).

staging: octeon-ethernet: fix TCP/UDP checksum calc

If the network portion of a frame is preceded by more than 14 bytes of
data, the checksum calculated in the HW is done over the wrong data and
is put in the wrong place.
In our use case an Octeon ethernet controller is connected to a Broadcom
switch chip. Extra data is included in the frame prior to egressing the
Octeon ethernet (i.e. 4 bytes of an 802.1Q tag, 4 bytes of a proprietary
BCM tag later stripped by the switch chip). This extra data causes the
checksum calculation to be incorrect.
The fix in this patch is to make use of the network header offset of the
skb. This enables the checksum to be calculated correctly.
This has been tested in both the configuration with the switch chip in
the egress path (as described above) and in a simple connection direct
to the wire.

All the IRQs for DPAA2 objects in the same DPRC must use
the ICID of that DPRC, as their device Id in the GIC-ITS.
Thus, all these IRQs must share the same ITT table in the GIC.
As a result, a pool of IRQs with the same device Id must be
preallocated per DPRC (fsl-mc bus instance). So, the fsl-mc
bus object allocator is extended to also provide services

staging: drop kbuild workaround dummy module from top dir

This is essentially a revert of 86f69fe9c069dd8608d238581eea259caa1dfc99
("Staging: workaround build system bug"), but to call it a revert would
imply it was wrong -- rather it seems more like it is just no longer
required anymore.

It doesn't list the full details of the failing use case, but the most
obvious would appear to be a "make allnoconfig" that subsequently had set
just CONFIG_STAGING=y in the .config file, to give:

  paul@builder:~/git/linux-head$ grep STAGING ../staging-allno/.config
  CONFIG_STAGING=y
  # CONFIG_STAGING_MEDIA is not set
  # CONFIG_STAGING_BOARD is not set
  paul@builder:~/git/linux-head$

After building this .config (on ARM, just to be different), we see that
built-in.o is created, and the final vmlinux links OK:

  paul@builder:~/git/linux-head$ ls -l ../staging-allno/drivers/staging/built-in.o
  -rw-rw-r-- 1 paul paul 257 Nov 16 18:06 ../staging-allno/drivers/staging/built-in.o
  paul@builder:~/git/linux-head$ file ../staging-allno/drivers/staging/built-in.o
  ../staging-allno/drivers/staging/built-in.o: ELF 32-bit LSB relocatable, ARM, version 1, not stripped
  paul@builder:~/git/linux-head$ nm ../staging-allno/drivers/staging/built-in.o
  nm: ../staging-allno/drivers/staging/built-in.o: no symbols
  paul@builder:~/git/linux-head$ ls -l ../staging-allno/vmlinux
  -rwxrwxr-x 1 paul paul 1236326 Nov 16 18:07 ../staging-allno/vmlinux
  paul@builder:~/git/linux-head$

I also tested an "allmodconfig" and did not see any problems there
either.  Switching back to x86-64 and testing several things there didn't
show any issues either.  So it appears we do not need to carry the
workaround in tree any longer.

staging: comedi: ni_mio_common: add finite regeneration to dio output

This patch continues the implementation of reinterpreting stop_arg when
stop_src == TRIG_NONE for national instruments cdio output on e/m-series
devices.  This is part of a series of patches that allow a user to have a
specific buffer repeated as-is indefinitely.  The contents of the DMA
buffer can be left static or changed by the user via mmap access to the DMA
buffer.  If the contents are changed by the user, additional munging is not
performed by the driver and only a single call to
comedi_mark_buffer_written should be done.  The original behavior is
preserved when stop_arg == 0, as would be the prior use case.

As opposed to analog output, this patch is relatively simple.  First, the
digital output capabilities are much more limited/simple as compared to the
analog output device on NI e/m-series hardware, and second, this patch
relies on changes made with the earlier patch to accomplish limiting the
DMA buffer transfer.

staging: comedi: ni_mio_common: Cleans up/clarifies ni_ao_cmd

This patch implements ni_ao_cmd much more closely organized like NI MHDDK
examples and DAQ-STC pseudo-code.  Adds comments with some more specific
references to the DAQ-STC.

For stop_src==TRIG_NONE (continuous output mode of entire buffer), the
count for the UC counter was corrected to represent the maximum count
possible (0xffffff).  Prior behavior for stop_src=TRIG_NONE did not
actually follow the DAQ-STC.  Furthermore, stop_src==TRIG_NONE now
correctly uses code specialized for either m-series or e-series devices.

It should be noted that stop_src==TRIG_NONE does _not_ with this patch
(or with prior behavior in ni_mio_common) actually implement true
continuous output.  Rather, the output is simply configured to operate as a
single buffer output, but where the buffer is as large as is possible with
NI-STC hardware.
