HAL RX descriptor for WCN6750 is same as QCN9074, this
means that the size of the HAL RX decriptor and the DP
APIs that WCN6750 requires to enable datapath should be
initialized with that of QCN9074's RX descriptor size
and the DP APIs respectively. There is one change wrt to
REO configuration though, REO configuration for WCN6750
follows WCN6855, therefore use reo_setup() of WCN6855
for WCN6750.

In the case of WCN6750, FW doesn't request for DDR memory
via QMI, instead it uses a fixed 12MB reserved Memory region
in the DDR which is called as MSA region. As a result, QMI
message sequence is not same as other ath11k supported devices.
Also, M3 firmware will be bundled into the FW and will be
downloaded to the target as part of Q6 boot.
This is the QMI flow in the case of WCN6750,
1) QMI firmware indication REQ/RESP
2) QMI host capability REQ/RESP
3) QMI target capability REQ/RESP
4) QMI device info REQ/RESP
5) QMI BDF download
6) QMI FW ready

WCN6750 uses static window mapping to access the HW registers.
Unlike QCN9074 which uses 3rd window for UMAC and 2nd window
for CE register access, WCN6750 uses 1st window for UMAC
and 2nd window for CE registers.
Also, refactor the code so that WCN6750 can use the existing
ath11k_pci_read32/write32() APIs for accessing the registers.

WCN6750 is a PCIe based solution that is attached to and enumerated
by the WPSS (Wireless Processor SubSystem) Q6 processor.
Though it is a PCIe device, since it is not attached to APSS processor
(Application Processor SubSystem), APSS will be unaware of such a decice
and hence it is registered to the APSS processor as a platform device(AHB).
Because of this hybrid nature, it is called as a hybrid bus device.
A new variable hybrid_bus_type is defined in hw_params to indicate the
hybrid nature of the device.
Add HW params for WCN6750.

In ath11k, bus_params were added with an intention to hold
parameters related to bus (AHB/PCI), but this is not true
as some bus parameters being different between chipsets of
the same bus.
With the addition of WCN6750 to ath11k, bus parameters are
going to be entirely different among AHB devices. Therefore,
it is wise to move bus_params to hw_params and get rid of
bus_params entirely.
Also, mhi_support parameter is not used anywhere in the driver,
remove it from bus_params.

Reason is:
When running disconnect operation, sta_info removed from local->sta_hash
by __sta_info_destroy_part1() from __sta_info_flush(), after this,
ieee80211_find_sta_by_ifaddr() which called by
ath11k_wmi_tlv_fw_stats_data_parse() and ath11k_wmi_tlv_rssi_chain_parse()
cannot find this station, then failed log printed.
steps are like this:
1. when disconnect from AP, __sta_info_destroy() called __sta_info_destroy_part1()
and __sta_info_destroy_part2().
2. in __sta_info_destroy_part1(), it has "sta_info_hash_del(local, sta)"
and "list_del_rcu(&sta->list)", it will remove the ieee80211_sta from the
list of ieee80211_hw.
3. in __sta_info_destroy_part2(), it called drv_sta_state()->ath11k_mac_op_sta_state(),
then peer->sta is clear at this moment.
4. in __sta_info_destroy_part2(), it then called sta_set_sinfo()->drv_sta_statistics()
->ath11k_mac_op_sta_statistics(), then WMI_REQUEST_STATS_CMDID sent to firmware.
5. WMI_UPDATE_STATS_EVENTID reported from firmware, at this moment, the
ieee80211_sta can not be found again because it has remove from list in
step2 and also peer->sta is clear in step3.
6. in __sta_info_destroy_part2(), it then called cleanup_single_sta()->
sta_info_free()->kfree(sta), at this moment, the ieee80211_sta is freed
in memory, then the failed log will not happen because function
ath11k_mac_op_sta_state() will not be called.
Actually this print log is not a real error, it is only to skip parse the
info, so change to skip print by default debug setting.

The device doesn't support outer header csum offload. However, inner TSO

After scan aborts we still receive some hw scan c2h packets, and
processing these c2h commands will change current channel. If device
already connect to other AP, driver will set wrong op channel due
to current channel changed. The disconnection happens when hw scan back
to wrong op channel that device can't receive beacon from AP. To fix
this issue, we ignore the late c2h if we are not scanning, and set
current channel back to op channel after scan to align the FW behavior.

Based on DesignWare Ethernet QoS datasheet, we are seeing the limitation
of Split Header (SPH) feature is not supported for Ipv4 fragmented packet.
This SPH limitation will cause ping failure when the packets size exceed
the MTU size. For example, the issue happens once the basic ping packet
size is larger than the configured MTU size and the data is lost inside
the fragmented packet, replaced by zeros/corrupted values, and leads to
ping fail.
So, disable the Split Header for Intel platforms.

With some SFP modules, such as Finisar FCLF8522P2BTL, the PHY hardware
strapping defaults to 1000BaseX mode, but the kernel prefers to set them
for SGMII mode. When this happens and the PHY is soft reset, the BMSR
status register is updated, but this happens after the kernel has already
read the PHY abilities during probing. This results in support not being
detected for, and the PHY not advertising support for, 10 and 100 Mbps
modes, preventing the link from working with a non-gigabit link partner.
When the PHY is being configured for SGMII mode, call genphy_read_abilities
again in order to re-read the capabilities, and update the advertising
field accordingly.

There is a desire to share the oclot_stats_layout struct outside of the
current vsc7514 driver. In order to do so, the length of the array needs to
be known at compile time, and defined in the struct ocelot and struct
felix_info.
Since the array is defined in a .c file and would be declared in the header
file via:
extern struct ocelot_stat_layout[];
the size of the array will not be known at compile time to outside modules.
To fix this, remove the need for defining the number of stats at compile
time and allow this number to be determined at initialization.
