Signed-off-by: David S. Miller <davem@davemloft.net>

Restrict the TTEthernet hardware support on this switch to operate as
closely as possible to IEEE 802.1Qci as possible. This means that it can
perform PTP-time-based ingress admission control on streams identified
by {DMAC, VID, PCP}, which is useful when trying to ensure the
determinism of traffic scheduled via IEEE 802.1Qbv.

The oddity comes from the fact that in hardware (and in TTEthernet at
large), virtual links always need a full-blown action, including not
only the type of policing, but also the list of destination ports. So in
practice, a single tc-gate action will result in all packets getting
dropped. Additional actions (either "trap" or "redirect") need to be
specified in the same filter rule such that the conforming packets are
actually forwarded somewhere.

Apart from the VL Lookup, Policing and Forwarding tables which need to
be programmed for each flow (virtual link), the Schedule engine also
needs to be told to open/close the admission gates for each individual
virtual link. A fairly accurate (and detailed) description of how that
works is already present in sja1105_tas.c, since it is already used to
trigger the egress gates for the tc-taprio offload (IEEE 802.1Qbv). Key
point here, we remember that the schedule engine supports 8
"subschedules" (execution threads that iterate through the global
schedule in parallel, and that no 2 hardware threads must execute a
schedule entry at the same time). For tc-taprio, each egress port used
one of these 8 subschedules, leaving a total of 4 subschedules unused.
In principle we could have allocated 1 subschedule for the tc-gate
offload of each ingress port, but actually the schedules of all virtual
links installed on each ingress port would have needed to be merged
together, before they could have been programmed to hardware. So
simplify our life and just merge the entire tc-gate configuration, for
all virtual links on all ingress ports, into a single subschedule. Be
sure to check that against the usual hardware scheduling conflicts, and
program it to hardware alongside any tc-taprio subschedule that may be
present.

The following scenarios were tested:

Implement tc-flower offloads for redirect, trap and drop using
non-critical virtual links.

Commands which were tested to work are:

  # Send frames received on swp2 with a DA of 42:be:24:9b:76:20 to the
  # CPU and to swp3. This type of key (DA only) when the port's VLAN
  # awareness state is off.

          action trap

  # Drop frames received on swp2 with a DA of 42:be:24:9b:76:20, a VID
  # of 100 and a PCP of 0.
  tc filter add dev swp2 ingress protocol 802.1Q flower skip_sw \
          dst_mac 42:be:24:9b:76:20 vlan_id 100 vlan_prio 0 action drop

Under the hood, all rules match on DMAC, VID and PCP, but when VLAN
filtering is disabled, those are set internally by the driver to the
port-based defaults. Because we would be put in an awkward situation if
the user were to change the VLAN filtering state while there are active
rules (packets would no longer match on the specified keys), we simply
deny changing vlan_filtering unless the list of flows offloaded via
virtual links is empty. Then the user can re-add new rules.

Virtual links are a sja1105 hardware concept of executing various flow
actions based on a key extracted from the frame's DMAC, VID and PCP.

Currently the tc-flower offload code supports only parsing the DMAC if
that is the broadcast MAC address, and the VLAN PCP. Extract the key
parsing logic from the L2 policers functionality and move it into its
own function, after adding extra logic for matching on any DMAC and VID.

As its implementation shows, this is synonimous with calling
dsa_slave_dev_check followed by dsa_slave_to_port, so it is quite simple
already and provides functionality which is already there.

However there is now a need for these functions outside dsa_priv.h, for
example in drivers that perform mirroring and redirection through
tc-flower offloads (they are given raw access to the flow_cls_offload
structure), where they need to call this function on act->dev.

But simply exporting dsa_slave_to_port would make it non-inline and
would result in an extra function call in the hotpath, as can be seen
for example in sja1105:

Before:

 6f8:	e1d416b0 	ldrh	r1, [r4, #96]	; 0x60
	u16 tx_vid = dsa_8021q_tx_vid(dp->ds, dp->index);
 6fc:	e1a08000 	mov	r8, r0

After:

000006e4 <sja1105_xmit>:
{
 6e4:	e92d4ff0 	push	{r4, r5, r6, r7, r8, r9, sl, fp, lr}
 6e8:	e1a04000 	mov	r4, r0
 6ec:	e24dd004 	sub	sp, sp, #4
	struct dsa_port *dp = dsa_slave_to_port(netdev);
 6f0:	e1a00001 	mov	r0, r1
{
 6f4:	e1a05001 	mov	r5, r1
	struct dsa_port *dp = dsa_slave_to_port(netdev);

 704:	ebfffffe 	bl	0 <dsa_8021q_tx_vid>
			704: R_ARM_CALL	dsa_8021q_tx_vid

Because we want to avoid possible performance regressions, introduce
this new function which is designed to be public.

First set of patches for v5.8. Changes all over, ath10k apparently
seeing most new features this time. rtw88 also had lots of changes due
to preparation for new hardware support.

In this pull request there's also a new macro to include/linux/iopoll:
read_poll_timeout_atomic(). This is needed by rtw88 for atomic
polling.

Major changes:

ath11k

* add debugfs file for testing ADDBA and DELBA

* add 802.11 encapsulation offload on hardware support

* add htt_peer_stats_reset debugfs file

ath10k

* enable VHT160 and VHT80+80 modes

* enable radar detection in secondary segment

* sdio: disable TX complete indication to improve throughput

* sdio: decrease power consumption

* sdio: add HTT TX bundle support to increase throughput

* sdio: add rx bitrate reporting

ath9k

* improvements to AR9002 calibration logic

carl9170

* remove buggy P2P_GO support

p54usb

* add support for AirVasT USB stick

rtw88

* add support for antenna configuration

ti wlcore

* add support for AES_CMAC cipher

iwlwifi

* support for a few new FW API versions

* new hw configs

Add QRTR MHI client driver

Here is the series adding MHI client driver support to Qualcomm IPC router
protocol. MHI is a newly added bus to kernel which is used to communicate to
external modems over a physical interface like PCI-E. This driver is used to
transfer the QMI messages between the host processor and external modems over
the "IPCR" channel.

For QRTR, this driver is just another driver acting as a transport layer like
SMD.

Currently this driver is needed to control the QCA6390 WLAN device from ath11k.
The ath11k MHI controller driver will take care of booting up QCA6390 and
bringing it to operating state. Later, this driver will be used to transfer QMI
messages over the MHI-IPCR channel.

The second patch of this series removes the ARCH_QCOM dependency for QRTR. This
is needed because the QRTR driver will be used with x86 machines as well to talk
to devices like QCA6390.

IPC Router protocol is also used by external modems for exchanging the QMI
messages. Hence, it doesn't always depend on Qualcomm platforms. One such
instance is the QCA6390 WLAN device connected to x86 machine.

MHI is the transport layer used for communicating to the external modems.
Hence, this commit adds MHI transport layer support to QRTR for
transferring the QMI messages over IPC Router.
