a34529e893 iwlwifi: rs: use const u16 for throughput tables
This makes the code a little bit longer as zero-extension
has to be done (mov vs. movzwl), but that's miniscule and
the space saving is significant, about 600 bytes in DVM
and 700 bytes in MVM, so the cache effect should be worth
the few bytes more code.

While at it, remove two spurious blank lines in variable
declaration blocks.

de06a59e36 iwlwifi: mvm: add bcast_filtering debugfs entries
Allow reading and setting bcast filtering configuration
through debugfs.

By default, mvm->bcast_filters is used for setting
the bcast filtering configuration (these filters
will be configured for each associated station).

For testing purposes, allow overriding this configuration,
and setting the bcast filtering configuration manually.
The following debugfs keys can be used:
* bcast_filtering/override - use debugfs values instead
	of default configuration
* bcast_filtering/filters - set filters (+ attributes)
* bcast_filtering/macs - per-mac bcast filtering
	configuration (policy + attached filters)

2ee8f021dd iwlwifi: mvm: add dest ip to bcast filter configuration
Add our ip as a new attribute to the bcast filtering
configuration (i.e. check the dest ip field of the
arp request).

Add bcast filter to pass incoming dhcp offer
broadcast frames as well (for sta vifs).

In order to support such dynamic configuration,
use the reserved1 field as a bitmap for driver internal
flags (which will indicate we want to configure the ip
in this attribute), and reconfigure the bcast
filtering on BSS_CHANGED_ARP_FILTER indication.

c87163b9ae iwlwifi: mvm: add basic bcast filtering implementation
Broadcast filtering allows dropping broadcast
frames that don't match the configured patterns.

Use predefined filters, and configure them for
each associated station vif.

There is no need to optimize and attach the same
filter to multiple vifs, as a following patch
will configure each filter to have per-vif unique
values.

Configure the bcast filtering on assoc changes.

Add a new IWLWIFI_BCAST_FILTERING Kconfig option
in order to enable broadcast filtering.

fc1471f061 iwlwifi: mvm: change the format of the SRAM dump
As a debug tool, we dump the SRAM from the device when an
error occurs. The main users of this want it in a different
format, so change the format to suit their needs.
Also - add a short delay between the prints to make sure
that the user space logger can catch up.

This happens only when the firmware asserts, and only when
fw_restart is set to 0 which is typically a testing
configuration.

1fb184b4a4 iwlwifi: mvm: limit non-low-latency binding scheduling duration
Limit the scheduling duration of bindings without a low-latency
interface in the firmware, this prevents those bindings from
occupying the medium for a period of time longer than what we
want for the other interfaces in low-latency mode.

As older firmware doesn't do anything with the max_duration field
and ignores it completely, there's no need for a firmware flag.

3e56eadfb6 iwlwifi: mvm: implement AP/GO uAPSD support
Newer firmware will support uAPSD clients in AP/GO mode, so complete
the driver support for it. The way it works is described in comments
in the code, but basically the driver just has to pass down all the
mac80211 requests and do accounting on agg/non-agg queues properly.

For older firmware, this doesn't change anything as it ignores the
fields used by the new firmware, and we only advertise uAPSD support
when the firmware does.

59f2e7df57 dma-debug: fix overlap detection
Commit 0abdd7a81b ("dma-debug: introduce debug_dma_assert_idle()") was
reworked to expand the overlap counter to the full range expressable by
3 tag bits, but it has a thinko in treating the overlap counter as a
pure reference count for the entry.

Instead of deleting when the reference-count drops to zero, we need to
delete when the overlap-count drops below zero.  Also, when detecting
overflow we can just test the overlap-count > MAX rather than applying
special meaning to 0.

Regression report available here:
http://marc.info/?l=linux-netdev&m=139073373932386&w=2

This patch, now tested on the original net_dma case, sees the expected
handful of reports before the eventual data corruption occurs.
