brcmfmac: use debugfs_create_devm_seqfile() helper function
Some time ago the function debugfs_create_devm_seqfile() was
introduced in debugfs. The caller simply needs to provide a
device pointer and read function. The function brcmf_debugfs_add_entry()
is now simply a wrapper only doing the work for CONFIG_BRCMDBG.

brcmfmac: remove watchdog reset from brcmf_pcie_buscoreprep()
The watchdog reset as done in brcmf_pcie_buscoreprep() is not
sufficient. It needs to modify PCIe core registers as well
which is properly done by brcmf_pcie_reset_device() after the
chip recognition is done. So the faulty watchdog reset can be
removed as it was causing driver reload to fail and hang the
system requiring a power-cycle. Instead the call to to the
brcmf_pcie_reset_device() function is done twice in the unload.

switchdev: documentation updates
Update the switchdev documentation to clarify that for IPV4 FIB object, the add
op is used for both adding and modifying the FIB entry on the device.
I found a few other white-space and grammer issues to fix, and to clarify the
static FDB ops.

Yanir provides 8 fixes and 1 version bump for e1000e. First fix resolves
a possible unit hang if multiple descriptors are available in the rings

on a suggested solution from Alex Duyck. Fixed a logical error, where
a "if" condition under which a flush should occur, was revered. Fixed
a hardware issue that prevented i219 from working in legacy interrupts
mode. Fixed the hardware clock configuration and suprious non-linear
increment. Lastly, fixed a system hang which occurred during execution
of "ethtool -t <NIC>", by disabling MULR for the loopback test to avoid

is misleadingly indented: the

independent of it (no braces before the "if" at line 1087).
This patch fixes the indentation to reflect the actual meaning of the code,
though is it actually meant to be part of the "else" clause? (I'm a
compiler developer, not a kernel person). It also adds spaces around
the assignment, to placate checkpatch.pl.
Seen via an experimental new gcc warning I'm working on for gcc 6,
-Wmisleading-indentation, using gcc r223098 adding
-Werror=misleading-indentation to KBUILD_CFLAGS in Makefile.
The experimental GCC emits this warning (as an error), rightly IMHO:

The command allows the driver get & set the DCDC's frequency tune.
(freq_tune is the divider that is used to calculate the actual DCDC's
clock rate)
The command always returns the current/updated frequency tune values of
the DCDC.

iwlwifi: prepare for higher API/CAPA bits
Currently, loading the firmware fails when it has higher API or CAPA
bits than the driver supports. That's an issue with integration.
At the same time, actually using api[0] and capa[0] will become
confusing when we also have api[1] and capa[1], and it's almost
certain that we'll mix up the bits and use the bits for api[1] with
api[0] by accident.
Avoid all this by translating the API/CAPA bits to the regular kernel
test_bit() format, and also providing wrapper functions. Also use the
__bitwise__ facility of sparse to check that we're testing the right
one.

iwlwifi: mvm: simplify iwl_mvm_stop_roc()
As pointed out by smatch, there's no need for a loop that always
immediately terminates. Use an if statement instead and while at
it clean up the mvmvif initialization.

iwlwifi: pcie: New RBD allocation model
As a preperation for multiple RX queues change the RBD
allocation model.
The new model includes a background allocator. The allocator is
called by the interrupt handler when there are two released
buffers by the queue, and the allocator starts allocating eight
pages per request.
When the queue has released 8 pages it tries claiming the
request. If the pages are not ready - it keeps claiming.
This new model should make sure that RBDs are always available
across the multiple queues.
The RBDs are transferred between the allocator and the queue.
The queue moves the free RBDs upon freeing them to the allocator.
The allocator moves them back to the queue's possession when the
request is claimed.
The allocator has an initial pool to make sure there are always RBDs
available for the request completion.
Release of the buffers at exit is done per pools - the allocator
frees its own initial pool and the queue frees its own pool.
Existing code refactor -
-Queue's initial pool is the size of the queue only as the allocation
of the new buffers no longer uses this pool.
-Removal of replenish background work, and replenish calls in the
interrupt handler and restock().
-The replenish() and the rxq used_list are used only during
initialization.
-Moved page allocation to a new function for code reuse.
New code -
Allocator code - new structure and functions.
Interrupt handler uses the allocator functions for replenishing buffers.
Reuse of the restock() method.
