Now that we have 512 queues, add a wait for single TX
queue to gen2.
This replaces gen1 wait_tx_queues_empty, which was limited
to 32 queues.

The original idea is to limit the maximum TDLS peer link, but the logic
is always false, and never be able to restrict the number of TDLS peer

Fix the logic here and also move the checking earlier, so that it could

QCA99X0, QCA9888, QCA9984 supports calibration data in
either OTP or DT/pre-cal file. Current ath10k supports
Calibration data from OTP only.
If caldata is loaded from DT/pre-cal file, fetching board id
and applying calibration parameters like tx power gets failed.
error log:

[ 15.741474] ath10k_pci 0000:01:00.0: could not probe fw (-2)

applying calibration parameters from cal data.

For SDIO the alignment requirement for transfers from device to host
is configured in firmware. This configuration is limited to minimum
of 4-byte alignment. However, this is not correct for platforms using
64-bit DMA when the minimum alignment should be 8 bytes. This issue
appeared when the ALIGNMENT definition was set according the DMA
configuration. The configuration in firmware was not using that macro
defintion, but a hardcoded value of 4. Hence the driver reported
alignment failures for data coming from the device and causing
transfers to fail.

This reverts commit b057886524be ("ath10k: do not use coherent memory for
allocated device memory chunks") in 2015 which converted this allocation from
dma_map_coherent() to kzalloc() / dma_map_single().
The current problem manifests when using later model NICs with larger
(>700KiB) scratch spaces in memory. Although the kzalloc call
succeeds, the software IOMMU TLB code (via dma_map_single()) panics
because it can't find 700KiB of linear physmem bounce buffers for DMA.
Now, this is a bit of a silly failure mode for the dma map API,
but it's what we currently have to play with.
In these cases, doing kzalloc() works fine, but the dma_map_single()
call fails.
After chatting with Linus briefly about this, it indeed should be
using dma_alloc_coherent() for doing larger device memory allocation
that requires some kind of physical address mapping.
You're not supposed to be using kzalloc and dma_map_* calls for
large memory regions, and I'm guessing not for long-held mappings
either. Typically dma mappings should be temporary for DMA,
not long held like these.
Now, since hopefully the major annoying underlying problem has also been
addressed (ie, ath10k is no longer tears down all of these allocations
and reallocates them every time the vdevs are brought down) fragmentation
should stop being such a touchy issue. If it is though, using
dma_alloc_coherent() use gets us access to the CMB APIs too relatively
easily and ideally we would be allocating memory early in boot for
exactly these reasons.

This patch adds support for new FullMAC WiFi driver for Quantenna
QSR10G chipsets.
QSR10G (aka Pearl) is Quantenna's 8x8, 160M, 11ac offering.
QSR10G supports 2 simultaneous WMACs - one 5G and one 2G.
5G WMAC supports 160M, 8x8 configuration. FW supports
up to 8 concurrent virtual interfaces on each WMAC.
Patch introduces 2 new drivers:
- qtnfmac.ko for interfacing with kernel wireless core
- qtnfmac_pearl_pcie.ko for interfacing with hardware over PCIe interface
