Current FIFO size calculation is wrong for two reasons:
- We access lmac 0 by default
- We don't take 11ax into consideration.
Fix both.

RB size can be configured by user to be greater than 4K.
That's needed for monitor to capture big AMSDUs.
The firmware now enables different RB sizes configuration

Today, the length of a debug message in iwl_trans_pcie_reclaim
may pass the MAX_MSG_LEN, which is 110.
An example for this kind of message is:
'iwl_trans_pcie_reclaim: Read index for DMA queue txq id (2),
last_to_free 65535 is out of range [0-65536] 2 2.'
Cut the message a bit so it will fit the allowed MAX_MSG_LEN.

If the HW is not responding at probe time, fail immediately complaining
about it. Without this, we see that the kernel spends > 100ms trying to
load firmware (even gives an incorrect impression that it actually
loaded a firmware) and do unnecesary processing before concluding that
the device is not accessible:

If the incoming frame should be an A-MSDU, it may already be one,
for example in the case of NAN multicast being encapsulated in an
A-MSDU. Thus, use the GSO algorithm to build A-MSDU only if the

Make the adjustments for gen2 TX and RX of TKIP packets. Strip MIC on
RX. Don't add IV space and keep the MIC space zeroed on TX.
Devices that support gen2 data path support TKIP only in station mode.
In all other modes, fall back to SW encryption. Do this early in the
set_key() callback so that the key flags would not be incorrectly set.

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.

Cleanup of the debug flow by moving several flows to separate
functions to increase readability. Three functions were created:
1. iwl_fw_get_prph_len - returns the size needed for periphery dump.
2. iwl_fw_dump_mem for - executes the memory dumping flow.
3. iwl_trans_get_fw_monitor_len - returns the size needed for monitor dump.

The ucode chunk might be relatively large and the allocation with
kmalloc() may fail occasionally. Since the data isn't DMA-transferred
but by manual loops, we can use vmalloc instead of kmalloc.
For a better performance, though, kvmalloc() would be the best choice
in such a case, so let's replace with it.

Using the NAPI or netdev frag cache along with other drivers can lead to
32 KiB pages being held for a long time, despite only being used for
very few page fragments.
This can happen if the driver grabs one or two fragments for rx ring
refill, while other drivers use (and free up) the remaining fragments.
The 32 KiB higher-order page can only be freed once all users have freed
their fragments.
Depending on the traffic patterns, this can waste a lot of memory and
look a lot like a memory leak.
