This patch enables tx and rx clock internal delay modes (TDM and RDM).
This is to address a failure in the case of 1Gbps communication using the
by salvator-x board with the KSZ9031RNX phy. This has been reported to
occur with both the r8a7795 (H3) and r8a7796 (M3-W) SoCs.
With this change APSR internal delay modes are enabled for
"rgmii-id", "rgmii-rxid" and "rgmii-txid" phy modes as follows:
phy mode | ASPR delay mode
-----------+----------------
rgmii-id | TDM and RDM
rgmii-rxid | RDM
rgmii-txid | TDM

DW GMAC databook says the following about bits in "Register 15 (Interrupt
Mask Register)":
--------------------------->8-------------------------
When set, this bit __disables_the_assertion_of_the_interrupt_signal__
because of the setting of XXX bit in Register 14 (Interrupt
Status Register).
--------------------------->8-------------------------
In fact even if we mask one bit in the mask register it doesn't prevent
corresponding bit to appear in the status register, it only disables
interrupt generation for corresponding event.
But currently we expect a bit different behavior: status bits to be in
sync with their masks, i.e. if mask for bit A is set in the mask
register then bit A won't appear in the interrupt status register.
This was proven to be incorrect assumption, see discussion here [1].
That misunderstanding causes unexpected behaviour of the GMAC, for
example we were happy enough to just see bogus messages about link
state changes.
So from now on we'll be only checking bits that really may trigger an
interrupt.

Modifying TIR hash should change selected fields bitmask in addition to
the function and key.
Formerly, Only on ethool mlx5e_set_rxfh "ethtoo -X" we would not set this
field resulting in zeroing of its value, which means no packet fields are
used for RX RSS hash calculation thus causing all traffic to arrive in
RQ[0].
On driver load out of the box we don't have this issue, since the TIR
hash is fully created from scratch.
Tested:
ethtool -X ethX hkey <new key>
ethtool -X ethX hfunc <new func>
ethtool -X ethX equal <new indirection table>
All cases are verified with TCP Multi-Stream traffic over IPv4 & IPv6.

We don't need to modify our TIRs unless the user requested a change in

# Modify TIRs hash is not needed

When tunneling is used, some virtualizations systems set the (mlx5e) uplink
device to be stacked under upper devices such as bridge or ovs internal
port, where the VTEP IP address used for the encapsulation is set on
that upper device.
In order to support such use-cases, we also deal with a setup where the
egress mirred device isn't representing a port on the HW e-switch to where
the ingress device belongs. We use eswitch service function which returns
the uplink and set it as the egress device of the tc encap rule.

We must re-enable RoCE on the e-switch management port (PF) only after destroying
the FDB in its switchdev/offloaded mode. Otherwise, when encapsulation is supported,
this re-enablement will fail.
Also, it's more natural and symmetric to disable RoCE on the PF before we create
the FDB under switchdev mode, so do that as well and revert if getting into error
during the mode change later.

On Rt3352 the driver needs to know the frequency of an external
crystal which can be either 40 MHz (as on all other WiSoCs until now)
or 20 MHz.
Get the clock attached by ramips WiSoC platform code which probes
SYSC_REG_SYSCFG (added by John Crispin in commit 6ac8579b96e3b) and
introduce a new flag clk_is_20mhz in struct hw_mode_spec to make the
driver aware and use either 40 MHz or 20 MHz specific rf_vals on those
WiSoC platforms.
The introduced support for boards with a 20 MHz crystal is also needed

Board Data File (BDF) is loaded upon driver boot-up procedure. The right
board data file is identified, among others, by device and sybsystem ids.
The problem, however, can occur when the (default) board data file cannot
fulfill with the vendor requirements and it is necessary to use a different
board data file.
To solve the issue QCA uses SMBIOS type 0xF8 to store Board Data File Name
Extension to specify the extension/variant name. The driver will take the
extension suffix into consideration and will load the right (non-default)
board data file if necessary.
If it is unnecessary to use extension board data file, please leave the
SMBIOS field blank and default configuration will be used.
Example:
If a default board data file for a specific board is identified by a string
"bus=pci,vendor=168c,device=003e,subsystem-vendor=1028,
subsystem-device=0310"
then the OEM specific data file, if used, could be identified by variant
suffix:
"bus=pci,vendor=168c,device=003e,subsystem-vendor=1028,
subsystem-device=0310,variant=DE_1AB"

The code in wmi_call uses the wil->wmi_call completion
structure to wait for a reply.
In some scenarios, complete was called twice on the
completion structure. This happened mainly with a disconnect
event which can arrive both unsolicited and as a reply to
a disconnect request. In this case the completion structure
was left marked as "done" and the next wmi_call returned
immediately with a corrupted reply buffer. This caused
unexpected results including crashes.
Fix this by adding the missing call to reinit_completion.

In case disable_ap_sme is true, driver doesn't turn-on

AP SME is passed to user space.
With AP SME disabled, driver reports assoc request frame
to user space which is then responsible for sending assoc
response frame and for sending NL80211_CMD_NEW_STATION.
Driver also reports disassoc frame to user space
which should then send NL80211_CMD_DEL_STATION.

8000 series adapters support filtering VXLAN, NVGRE and GENEVE traffic
based on inner fields, and when the NIC recognises such traffic, it
does not match unencapsulated traffic filters any more. So add catch-
all filters for encapsulated traffic on supporting platforms.
Although recognition of VXLAN and GENEVE is based on UDP ports, and thus
will not occur until the driver (on the primary PF) notifies the
firmware of UDP ports to use, NVGRE will always be recognised, hence
without this patch 8000 series adapters will drop all NVGRE traffic.
