Initial QCA99X0 support has a known issue with TCP Tx throughput.
All other path such as UDP Tx/Rx and TCP Rx meet their expectation
(> 900Mbps), but TCP Tx marked as low as 5Mbps when single pair is
used on iperf.

The root cause is turned out because TSO flag is not initialized
properly so that firmware configures TSO in wrong way.
TSO flags in msdu extension descriptor is required to be reset
to indicate firmware there is no TSO is enabled, otherwise it
could act as TSO is enabled which causes huge throughput drop.

In fact, it's enough by resetting TSO flags only to prevent the
unexpected behavior, but initializing whole msdu ext. descriptor
will help to clear uncertainty of firmware could bring on as it
constantly updated.

Host memory required for firmware is allocated while handling
wmi service ready event. Right now, wmi service ready is handled
in tasklet context and it calls dma_alloc_coherent() with atomic
flag (GFP_ATOMIC) to allocate memory in host needed for firmware.
The problem is, dma_alloc_coherent() with GFP_ATOMIC fails in
the platform (at least in AP platform) where it has less atomic
pool memory (< 2mb). QCA99X0 requires around 2 MB of host memory
for one card, having additional QCA99X0 card in the same platform
will require similarly amount of memory. So, it's not guaranteed that
all the platform will have enough atomic memory pool.

Fix this issue, by handling wmi service ready event in workqueue
context and calling dma_alloc_coherent() with GFP_KERNEL. mac80211 work
queue will not be ready at the time of handling wmi service ready.
So, it can't be used to handle wmi service ready. Also, register work
gets scheduled during insmod in existing ath10k_wq and waits for
wmi service ready to completed. Both workqueue can't be used for
this purpose. New auxiliary workqueue is added to handle wmi service
ready.

This patch enables raw Rx/Tx encap mode to support software based
crypto engine. This patch introduces a new module param 'cryptmode'.

 cryptmode:

   0: Use hardware crypto engine globally with native Wi-Fi mode TX/RX
      encapsulation to the firmware. This is the default mode.
   1: Use sofware crypto engine globally with raw mode TX/RX
      encapsulation to the firmware.

Known limitation:
   A-MSDU must be disabled for RAW Tx encap mode to perform well when
   heavy traffic is applied.

When using DFS channels on Ath10k, kernel log has repeated warning message
'failed to process fft: -22' typically under medium/heavy traffic.

This patch switches the warnings to driver debug (WMI events) mode only
thus reducing log file noise.

DFS and spectral scan share underlying HW mechanisms and enabling one
(DFS) enables the other (spectral scan) as far as event reporting from
firmware to driver is concerned. Spectral scan events take no part in
processing of DFS radar pulses which are delivered as distinct events,
so the fft (spectral event) warning is harmless and DFS interference
detection/protection still occurs.

HTT_H2T_MSG_TYPE_MGMT_TX msg in 10.4 firmware carries additional
4 byte in htt_mgmt_tx_desc where it tells to firmware that at what
rate mgmt frame has to go out in the air. It's an optional parameter,
setting this field to zero will force firmware to choose auto rate
and send the frame out.

Those 4 byte info is missed out in the current code and 10.4 firmware
ended up reading some junk in those 4 byte and sometime malfunctioning.

Fix it by adding 4 byte in struct htt_mgmt_tx_desc. Non 10.4 firmware
will not process those four byte. So, adding 4 byte at the end of
struct htt_mgmt_tx_desc will not create any impact on other chipset.

====================
be2net: patch set

Hi David, the following patch set has code cleanup patches, minor enhancements
and non-critical fixes. Pls consider applying to the net-next tree. Thanks!

Patch 1 removes duplicate code in be_setup_wol() routine making it simpler
and more readable.

Patch 2 fixes the the bridge mode return value for the ndo_bridge_getlink()
call. Instead of just relying on the SRIOV enabled state, the driver now
queries the FW, for the actual mode of bridge.

Patch 3 removes code for setting D0 power state as it's already done
in pci_enable_device()

Patch 4 fixes a bad return value in be_check_ufi_compatibility() routine
introduced by an earlier commit.

Patch 5 fixes a field in udp header being accessed while in network endian
format.

Patch 6 fixes the be_mcc_notify() routine to return an error status when
the FW/HW is in an error state.

Patch 7 fixes the be_cmd_rx_filter() routine to issue the RX_FILTER cmd
and not wait for a completion from the FW. If the FW/adapter
is in an error state, this change helps in not holding up the rtnl_lock
and keeping bottom halves disabled while the driver timesout waiting for
a response from the FW.

Patch 8 fixes the be_cmd_set_loopback() routine to issue the LOOPBACK cmd
and not wait for the FW completion while spin_lock_bh() is held on the
mcc_lock. As the cmd is always issued from ethtool in a process context,
it can sleep till the FW completion is received.

Patch 9 bumps up the driver version to 10.6.0.3

The SET_LOOPBACK_MODE command is always issued from ethtool only in a
process context. So, while waiting for the cmd to complete, the driver
can sleep instead of holding spin_lock_bh() on the mcc_lock. This is done
by calling be_mcc_notify() instead of be_mcc_notify_wait() (that returns
only after the cmd completes while the MCCQ is locked).

This fix makes the RX_FILTER cmd asynchronous, i.e., the caller issues
this cmd and doesn't wait for a completion from the FW. If the FW/adapter
is in an error state, this change helps in not holding up the rtnl_lock
and keeping bottom halves disabled while the driver timesout waiting for
a response from the FW.

When the adapter is in error state, return error from be_mcc_notify()
so that the caller routines need not sleep waiting for a response.

The "dest" field in the UDP-hdr of a TX skb is in network endian format.
Convert it to host endian before accessing it. The os2bmc patch,
mentioned below introduced this code.

In the commit a6e6ff6e
("be2net: simplify UFI compatibility checking"), a return value of "-1"
was incorrectly used in place of "false". This patch fixes it.
