According to the DT binding, the Ethernet core interrupt is optional.
Use platform_get_irq_optional() to avoid the error message when the
IRQ is not specified.

Especially with the default 32-bit DMA mask, DMA buffers are a limited
resource, so their allocation can fail.
So as the DMA API documentation requires, add error checking code after
dma_map_single() calls to catch the case where we run out of "low" memory.

Factor out the code that cleans up a number of connected TX descriptors,
as we will need it to properly roll back a failed _xmit() call.
There are subtle differences between cleaning up a successfully sent
chain (unknown number of involved descriptors, total data size needed)
and a chain that was about to set up (number of descriptors known), so
cater for those variations with some extra parameters.

Since 0 is a valid DMA address, we cannot use the physical address to
check whether a TX descriptor is valid and is holding a DMA mapping.
Use the "cntrl" member of the descriptor to make this decision, as it
contains at least the length of the buffer, so 0 points to an
uninitialised buffer.

When axienet_dma_bd_init() bails out during the initialisation process,
it might do so with parts of the structure already allocated and
initialised, while other parts have not been touched yet. Before
returning in this case, we call axienet_dma_bd_release(), which does not
take care of this corner case.
This is most obvious by the first loop happily dereferencing
lp->rx_bd_v, which we actually check to be non NULL *afterwards*.
Make sure we only unmap or free already allocated structures, by:
- directly returning with -ENOMEM if nothing has been allocated at all
- checking for lp->rx_bd_v to be non-NULL *before* using it
- only unmapping allocated DMA RX regions
This avoids NULL pointer dereferences when initialisation fails.

When we fail allocating the DMA buffers in axienet_dma_bd_init(), we
report this error, but carry on with initialisation nevertheless.
This leads to a kernel panic when the driver later wants to send a
packet, as it uses uninitialised data structures.
Make the axienet_device_reset() routine return an error value, as it
contains the DMA buffer initialisation. Make sure we propagate the error
up the chain and eventually fail the driver initialisation, to avoid
relying on non-initialised buffers.

The DMA error handler routine is currently a tasklet, scheduled to run
after the DMA error IRQ was handled.
However it needs to take the MDIO mutex, which is not allowed to do in a

Similar to axienet, the temac driver is now architecture agnostic, and
can be at least compiled for several architectures.
Especially the fact that this is a soft IP for implementing in FPGAs
makes the current restriction rather pointless, as it could literally
appear on any architecture, as long as an FPGA is connected to the bus.
The driver hasn't been actually tried on any hardware, it is just a
drive-by patch when doing the same for axienet (a similar patch for
axienet is already merged).
This (temac and axienet) have been compile-tested for:
alpha hppa64 microblaze mips64 powerpc powerpc64 riscv64 s390 sparc64
(using kernel.org cross compilers).

Kalle Valo says:
====================
wireless-drivers-next patches for v5.7
Second set of patches for v5.7. Lots of cleanup patches this time, but
of course various new features as well fixes.
When merging with wireless-drivers this pull request has a conflict in:
drivers/net/wireless/intel/iwlwifi/pcie/drv.c
To solve that just drop the changes from commit cf52c8a776d1 in
wireless-drivers and take the hunk from wireless-drivers-next as is.
The list of specific subsystem device IDs are not necessary after
commit d6f2134a3831 (in wireless-drivers-next) anymore, the detection
is based on other characteristics of the devices.
Major changes:
qtnfmac
* support WPA3 SAE and OWE in AP mode
ath10k
* support for getting btcoex settings from Device Tree
* support QCA9377 SDIO device
ath11k
* add HE rate accounting
* add thermal sensor and cooling devices
mt76
* MT7663 support for the MT7615 driver

The following modify sequence (loosely based on ipoib) will lose a pkey
modifcation:
- Modify (pkey index, port)
- Modify (new pkey index, NO port)
After the first modify, the qp_pps list will have saved the pkey and the
unit on the main list.
During the second modify, get_new_pps() will fetch the port from qp_pps
and read the new pkey index from qp_attr->pkey_index. The state will
still be zero, or IB_PORT_PKEY_NOT_VALID. Because of the invalid state,
the new values will never replace the one in the qp pps list, losing the
new pkey.
This happens because the following if statements will never correct the
state because the first term will be false. If the code had been executed,
it would incorrectly overwrite valid values.
if ((qp_attr_mask & IB_QP_PKEY_INDEX) && (qp_attr_mask & IB_QP_PORT))
new_pps->main.state = IB_PORT_PKEY_VALID;
if (!(qp_attr_mask & (IB_QP_PKEY_INDEX | IB_QP_PORT)) && qp_pps) {
new_pps->main.port_num = qp_pps->main.port_num;
new_pps->main.pkey_index = qp_pps->main.pkey_index;
if (qp_pps->main.state != IB_PORT_PKEY_NOT_VALID)
new_pps->main.state = IB_PORT_PKEY_VALID;
}
Fix by joining the two if statements with an or test to see if qp_pps is
non-NULL and in the correct state.

In striding RQ mode, the buffers of an RX WQE are first

We maintain the state of these in-progress WQEs in the RQ
SW struct.
In the flow of ICOSQ recovery, the corresponding RQ is not
in error state, hence:
- The buffers of the in-progress WQEs must be released
and the RQ metadata should reflect it.
- Existing RX WQEs in the RQ should not be affected.
For this, wrap the dealloc of the in-progress WQEs in
a function, and use it in the ICOSQ recovery flow
instead of mlx5e_free_rx_descs().

The SJA1105 switch family has a PTP_CLK pin which emits a signal with
fixed 50% duty cycle, but variable frequency and programmable start time.
On the second generation (P/Q/R/S) switches, this pin supports even more
functionality. The use case described by the hardware documents talks
about synchronization via oneshot pulses: given 2 sja1105 switches,
arbitrarily designated as a master and a slave, the master emits a
single pulse on PTP_CLK, while the slave is configured to timestamp this
pulse received on its PTP_CLK pin (which must obviously be configured as
input). The difference between the timestamps then exactly becomes the
slave offset to the master.
The only trouble with the above is that the hardware is very much tied
into this use case only, and not very generic beyond that:
- When emitting a oneshot pulse, instead of being told when to emit it,
the switch just does it "now" and tells you later what time it was,
via the PTPSYNCTS register. [ Incidentally, this is the same register
that the slave uses to collect the ext_ts timestamp from, too. ]
- On the sync slave, there is no interrupt mechanism on reception of a
new extts, and no FIFO to buffer them, because in the foreseen use
case, software is in control of both the master and the slave pins,
so it "knows" when there's something to collect.
These 2 problems mean that:
- We don't support (at least yet) the quirky oneshot mode exposed by
the hardware, just normal periodic output.
- We abuse the hardware a little bit when we expose generic extts.
Because there's no interrupt mechanism, we need to poll at double the
frequency we expect to receive a pulse. Currently that means a
non-configurable "twice a second".

The AVB table contains the CAS_MASTER field (to be added in the next
patch) which decides the direction of the PTP_CLK pin.
Reconfiguring this field dynamically is highly preferable to having to
reset the switch and upload a new static configuration, so we add
support for exactly that.

Because the PTP_CLK pin starts toggling only at a time higher than the
current PTP clock, this helper from the time-aware shaper code comes in
handy here as well. We'll use it to transform generic user input for the
perout request into valid input for the sja1105 hardware.

These fields configure the destination and source MAC address that the
switch will put in the Ethernet frames sent towards the CPU port that
contain RX timestamps for PTP.
These fields do not enable the feature itself, that is configured via
SEND_META0 and SEND_META1 in the General Params table.
The implication of this patch is that the AVB Params table will always
be present in the static config. Which doesn't really hurt.
This is needed because in a future patch, we will add another field from
this table, CAS_MASTER, for configuring the PTP_CLK pin function. That
can be configured irrespective of whether RX timestamping is enabled or
not, so always having this table present is going to simplify things a
bit.

The allocated ieee_ets structure goes out of scope without being freed,
leaking memory. Appropriate result codes should be returned so that
callers do not rely on invalid data passed by reference.
Also cache the ETS config retrieved from the device so that it doesn't
need to be freed. The balance of the code was clearly written with the
intent of having the results of querying the hardware cached in the
device structure. The commensurate store was evidently missed though.

There is an indexing bug in determining these ethtool priority
counters. Instead of using the queue ID to index, we need to
normalize by modulo 10 to get the index. This index is then used
to obtain the proper CoS queue counter. Rename bp->pri2cos to
bp->pri2cos_idx to make this more clear.

Packet trap groups are now explicitly registered by drivers and not
implicitly registered when the packet traps are registered. Therefore,
there is no need to encode entire group structure the trap is associated
with inside the trap structure.
Instead, only pass the group identifier. Refer to it as initial group
identifier, as future patches will allow user space to move traps
between groups.
