The MSCC bug fix in 'net' had to be slightly adjusted because the
register accesses are done slightly differently in net-next.

There are several "flavors" of HW that have the same HW type, but
can be told apart after reading a certain perph register. This
is easy to do in runtime, but more complicated to do when looking
at the logs offline.
To make it easier to tell apart these "flavors" when looking at
the dumped dbg info, add these bits to the HW type, allowing
simple differentiation.

We don't really expect fragmented RBs, and don't seem to be seeing
them in practice since that would've caused a crash. Nevertheless,
we should be expecting the hardware to send them.
Parse the flag indicating a fragmented buffer, but then discard it
and any fragments thereof, at least for now. We need to do more
work in the higher layers to properly deal with this, since we may
not get "normal" firmware notifications that are fragmented, only
RX, and then we need to put it back together and add the necessary
API to report a chain of things to the higher layers, this doesn't
fit into the struct iwl_rx_cmd_buffer today.

We can currently end up transmitting on an unallocated queue, if
the allocation fails. Stop doing that, by simply not transmitting.
We don't have any better strategy here, unfortunately, but the
previous commits make that much less likely.

When we have 256 block-ack support, we may need to be very fast
to provide a lot of frames to the hardware to transmit, but that
cannot be guaranteed. Use a longer queue size to have more time,
and the next possible queue size is 1024 since it must be a power
of two.

Since the recent patch in this area, we no longer allocate 64k
for a single queue, but only 1k, which still means a full page.
Use a DMA pool to reduce this further, since we will have a lot
of queues in a typical system that can share pages.

We currently attempt to allocate queues that are 512 entries long,
but that requires 32 KiB memory, which may not be available, at
least not contiguously. If we fail to allocate, attempt to use a
smaller queue all the way down to 16 entries (which fit into a
single page).

The hardware needs a byte-count table with the size of each frame
on the queue to build A-MPDUs, but:
* newer generation no longer have the duplicated space at the end,
they can deal with the wrap properly - and we don't even fill
the dup anyway
* we have a maximum queue size of 512 right now and don't use the
theoretical hardware maximum of 65536.
Together, this reduces the byte count table DMA allocation from
64KiB (65536*2 + 64*2 rounded up) to 1 KiB (though that might be
rounded up to a full 4 KiB page by the allocator, not sure it can
share the allocations.)

For ACK_ENABLED and 32BIT_BA_BITMAP flags check the station capabilities
rather than bss_conf.ack_enabled and bss_conf.multi_sta_back_32bit.
These fields are stations capabilities and should not be in bss_conf.
Also note that the bss_conf flags are set in station mode only.
In the next patch I will remove ack_enabled and multi_sta_back_32bit
from the bss_conf structure.

If we set amsdu_len one after another the second one overwrites
the orig_amsdu_len so allow only moving from debug to non debug state.
Also the TLC update check was wrong: it was checking that also the orig
is smaller then the new updated size, which is not the case in debug
amsdu mode.

This module parameter should not be mangled by users.
This relates to a very old driver and I doubt people can
really check the antenna coupling in a way that would make
