4244e7fc70 iwlwifi: dump debug data before stop device
Debug data dump is not working in flows that stop the device is used
in their error handling. During these flows the op mode mutex is
locked until the device stops.  Because of that, any assert generated
from the firmware can be handled only after the device already
stopped.

Since dumping cannot occour after stopping the device, split the the
dump function to two parts, Part that handles locking, and the part
that starts the actual dumping and call the second part in the op mode
stop device function.

af303252bf iwlwifi: dbg: decrement occurrences for all triggers
iwl_fw_dbg_collect can be called by any function that already
has the error string ready. iwl_fw_dbg_collect_trig, on the
other hand, does string formatting. The occurrences decrement
is at iwl_fw_dbg_collect_trig, instead of iwl_fw_dbg_collect,
which causes it to sometimes be skipped. Move it to the right
location.

e7eeee0843 iwlwifi: nvm: get num of hw addresses from firmware
With NICs that don't read the NVM directly and instead rely on getting
the relevant data from the firmware, the number of reserved MAC
addresses was not added to the API. This caused the driver to assume
there is only one address which results in all interfaces getting the
same address. Update the API to fix this.

While at it, fix-up the comments with firmware api names to actually

79f25b10c9 iwlwifi: dbg: don't crash if the firmware crashes in the middle of a debug dump
We can dump data from the firmware either when it crashes,
or when the firmware is alive.
Not all the data is available if the firmware is running
(like the Tx / Rx FIFOs which are available only when the
firmware is halted), so we first check that the firmware
is alive to compute the required size for the dump and then
fill the buffer with the data.

When we allocate the buffer, we test the STATUS_FW_ERROR
bit to check if the firmware is alive or not. This bit
can be changed during the course of the dump since it is
modified in the interrupt handler.

We hit a case where we allocate the buffer while the
firmware is sill working, and while we start to fill the
buffer, the firmware crashes. Then we test STATUS_FW_ERROR
again and decide to fill the buffer with data like the
FIFOs even if no room was allocated for this data in the
buffer. This means that we overflow the buffer that was
allocated leading to memory corruption.

To fix this, test the STATUS_FW_ERROR bit only once and
rely on local variables to check if we should dump fifos
or other firmware components.

The tid for Non-QOS frames is set to IWL_MAX_TID_COUNT. This value
is also used for configuring the queue for non-QOS data. However, this
tid is used by the FW for management queues. As a result, the FW
does not encrypt non-QOS data frames.

Fix this by setting the tid for non-QOS data frames to zero, which
is a valid value for data frames in the FW.

This also fixes a bug in sending multicast frames, where the queues
are allocated with tid == 0, but are sent with tid == 8, which may
lead to unexpected behavior.

dd2690579f iwlwifi: runtime: avoid calling debugfs read functions more than once
Upon first calling read() on a debugfs file, invoke
iwl_dbgfs_##name##_read and store the response buffer on the heap, so
subsequent read() calls don't need to invoke said function again.

This is done because cat etc will call read() repeatedly until EOF is
reached (or read() returns 0), which in the current implementation will
cause said function to be invoked multiple times.

With the current implementation this can also cause buggy behavior in
some weird edge cases where the first invocation returns a string of
length n, and the second of length m>n: The last m-n characters of
the second invocation will be printed to screen.
