ecc7c518b3 iwlwifi: mvm: fix a race in D0i3 vs. Tx path
When we enter D0i3, we must stop TXing otherwise the
sequence number we use might conflict with the firmware's
internal TX. In order to do so, we have
IWL_MVM_STATUS_IN_D0I3 which should prevent any Tx while we
enter D0i3. There is a bug in this code since we may Tx even
if IWL_MVM_STATUS_IN_D0I3 is set. This can happen as long as
mvm->d0i3_ap_sta_id is not set.

To make sure that we don't have any packet in the Tx path
while we set mvm->d0i3_ap_sta_id, call synchronize_net only
after we already set mvm->d0i3_ap_sta_id.

b3df224754 iwlwifi: mvm: don't disconnect on beacon loss in D0I3
Currently if we wake up during D0I3 due to beacon loss we disconnect
immediately. This behaviour causes redundant disconnection, which could
be prevented by polling as it is usually done in mac80211.
Instead, we prefer reporting beacon loss and let mac80211 try polling
before disconnection.

3cd6e2f768 iwlwifi: convert hex_dump_to_buffer() to %*ph
There is no need to use hex_dump_to_buffer() in the cases like this:

	hexdump_to_buffer(buf, len, 16, 1, outbuf, outlen, false);	/* len <= 16 */
	sprintf("%s\n", outbuf);

since it maybe easily converted to simple:

	sprintf("%*ph\n", len, buf);

Note: it seems in one case the output is groupped by 2 bytes and looks like a
typo. Thus, patch changes that to plain byte stream.

e112018776 iwlwifi: mvm: Add FW paging mechanism for the UMAC on SDIO
Family 8000 products has 2 embedded processors, the first
known as LMAC (lower MAC) and implements the functionality from
previous products, the second one is known as UMAC (upper MAC)
and is used mainly for driver offloads as well as new features.
The UMAC is typically “less” real-time than the LMAC and is used
for higher level controls.
The UMAC's code/data size is estimated to be in the mega-byte arena,
taking into account the code it needs to replace in the driver and
the set of new features.

In order to allow the UMAC to execute code that is bigger than its code
memory, we allow the UMAC embedded processor to page out code pages on
DRAM.

When the device is slave on the bus(SDIO) the driver saves the UMAC's
image pages in blocks of 32K in the DRAM and sends the layout of the
pages to the FW. When the FW wants load / unload pages, it creates an
interrupt,	and the driver uploads / downloads the page to an address in
the a specific address on the device's memory.

The driver can support up to 1 MB of pages.

Add paging mechanism for the UMAC on SDIO in order to allow the program to
use a larger virtual space while using less physical memory on the device
itself.

26d535aedc 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.

93190fb058 iwlwifi: mvm: Enable Rx Checksum hw
TCP software implementation on the host requires extensive computing
power.  Offloading even some of the TCP/IP stack to the NIC might save
a significant overhead. In order to enable this feature on our hw,
we need to configure it first. Once done, we mark this capability,
to be advertised later to the OS via ieee80211_register_hw.
The driver Rx indications for TCP Checksum is integrated within the
standard Rx status. The driver responds to those indications as follows:
If the frame was tested by hw and checksum ok report CHECKSUM_UNNECESSARY.
Otherwise, report CHECKSUM_NONE.

869f3b15c9 iwlwifi: pcie: provide a way to stop configuration if it is forbidden
The firmware debug infrastructure allows the user to
provide a firmware that will toggle a few registers to
configure the debugging capabilities.
On certain devices, certain operations are forbidden.
Executing a forbidden operation will cause the hardware to
die in a way that only driver unload / load will bring it
back to life.
Fortunately, there is a way to know in advance if those
operations will be accepted by the device. This is where
the new PRPH_BLOCKBIT operation plays its role. If the bit
X from PRPH register Y is set, then we should prevent any
further register configuration. When that happens, drop a
line in the kernel log since this is really an error state:
the user won't have his device configured as he expected.
Add operations that will be used in the future:
INDIRECT_ASSIGN, INDIRECT_SETBIT, and INDIRECT_CLEARBIT.

Other debugging configurations (such as destination
configuration for the monitor) will take place in any case.

d0ab08d05e iwlwifi: mvm: Use the AP station for non_sta transmit
In iwl_mvm_tx_skb_non_sta(), in case of managed interface,
use the AP station for multicast frames instead of the auxiliary
station as otherwise the frames can be sent to an absent P2P GO as
the FW does not block transmissions for the auxiliary station
since it is not associated with the station MAC context.

Note that this is not possible for unicast frames, as a TDLS
discovery response is sent without a station entry, and in this
case the P2P GO NoA should not block transmission to the peer.

2d42801bd6 Revert "iwlwifi: mvm: move deferred d0i3 exit to resume_complete op"
This reverts commit 088070a2f6.

When working in d0i3_on_idle mode, we explicitly go out
of d0i3 on resume (so other potential commands could
be sent).

However, D0I3_DEFER_WAKEUP is currently cleared on
resume complete (which happens only later on), causing
d0i3 exit to timeout.

Since mac80211 was modified to accept incoming frames
once drv_resume was called, we can safely revert this
patch, and handle the pending work on iwl_mvm_resume().

88742c9e84 iwlwifi: mvm: move existing UMAC commands to group 1
Existing UMAC commands already use the long header, but are sent
with group 0 and the long header inserted manually. Move them to
the group 1 to take advantage of the header building in the low-
level transport.

Existing firmware ignores the group_id field (it's reserved) and
the first firmware that really supports long command headers can
parse all commands in both group 0 (with short header) and group
1 (with long header.)

ab02165cce iwlwifi: add wide firmware command infrastructure for TX
As the firmware is slowly running out of command IDs and grouping of
commands is desirable anyway, the firmware is extending the command
header from 4 bytes to 8 bytes to introduce a group (in place of the
former flags field, since that's always 0 on commands and thus can
be easily used to distinguish between the two.

In order to support this most easily in the driver widen the command
command ID used in the command sending functions and encode the new
values (group and version) in the ID. That way existing code doesn't
have to be changed (since the higher bits are 0 automatically) and
newer code can easily use the new ID generation function to create a
value to use in place of just the command ID.
