Implement the .support_eee() method to indicate that EEE is not
supported by two switch variants, rather than making these checks in
the .set_mac_eee() and .get_mac_eee() methods.

ptp4l would fail to take TX timestamps of Pdelay_Resp messages like this:
increasing tx_timestamp_timeout may correct this issue, but it is likely caused by a driver bug
ptp4l[4134.168]: port 2: send peer delay response failed
It turns out that the driver can't take their TX timestamps because it
can't transmit them in the first place. And there's nothing special
about the Pdelay_Resp packets - they're just regular 68 byte packets.
But with this taprio configuration, the switch would refuse to send even
the ETH_ZLEN minimum packet size.
This should have definitely not been the case. When applying the taprio
config, the driver prints:

and thus, everything under 132 bytes - ETH_FCS_LEN should have been sent
without problems. Yet it's not.
For the forwarding path, the configuration is fine, yet packets injected
from Linux get stuck with this schedule no matter what.
The first hint that the static guard bands are the cause of the problem
is that reverting Michael Walle's commit 297c4de6f780 ("net: dsa: felix:
re-enable TAS guard band mode") made things work. It must be that the
guard bands are calculated incorrectly.
I remembered that there is a magic constant in the driver, set to 33 ns
for no logical reason other than experimentation, which says "never let
the static guard bands get so large as to leave less than this amount of
remaining space in the time slot, because the queue system will refuse
to schedule packets otherwise, and they will get stuck". I had a hunch
that my previous experimentally-determined value was only good for
packets coming from the forwarding path, and that the CPU injection path
needed more.
I came to the new value of 35 ns through binary search, after seeing
that with 544 ns (the bit time required to send the Pdelay_Resp packet
at gigabit) it works. Again, this is purely experimental, there's no
logic and the manual doesn't say anything.
The new driver prints for this schedule look like this:
mscc_felix 0000:00:00.5: port 0 tc 0 min gate length 1250 ns not enough for max frame size 1526 at 1000 Mbps, dropping frames over 131 octets including FCS

mscc_felix 0000:00:00.5: port 0 tc 3 min gate length 1250 ns not enough for max frame size 1526 at 1000 Mbps, dropping frames over 131 octets including FCS
mscc_felix 0000:00:00.5: port 0 tc 4 min gate length 1250 ns not enough for max frame size 1526 at 1000 Mbps, dropping frames over 131 octets including FCS
mscc_felix 0000:00:00.5: port 0 tc 5 min gate length 1250 ns not enough for max frame size 1526 at 1000 Mbps, dropping frames over 131 octets including FCS

mscc_felix 0000:00:00.5: port 0 tc 7 min gate length 1250 ns not enough for max frame size 1526 at 1000 Mbps, dropping frames over 131 octets including FCS
So yes, the maximum MTU is now even smaller by 1 byte than before.
This is maybe counter-intuitive, but makes more sense with a diagram of
one time slot.
Before:
Gate open Gate close
| |
v 1250 ns total time slot duration v
<---------------------------------------------------->
<----><---------------------------------------------->
33 ns 1217 ns static guard band
useful
Gate open Gate close
| |
v 1250 ns total time slot duration v
<---------------------------------------------------->
<-----><--------------------------------------------->
35 ns 1215 ns static guard band
useful
The static guard band implemented by this switch hardware directly
determines the maximum allowable MTU for that traffic class. The larger
it is, the earlier the switch will stop scheduling frames for
transmission, because otherwise they might overrun the gate close time
(and avoiding that is the entire purpose of Michael's patch).
So, we now have guard bands smaller by 2 ns, thus, in this particular
case, we lose a byte of the maximum MTU.

Rather than maintaining a private copy of the LPI timer, make use of
the LPI timer maintained by phylib. In any case, phylib overwrites the
value of tx_lpi_timer set by the driver in phy_ethtool_get_eee().
Note that feb->eee.tx_lpi_timer is initialised to zero, which is just
the same with phylib's copy, so there should be no functional change.

The device does not support multiple mirror actions per rule and the

# tc filter add dev swp1 ingress pref 1 proto ip flower skip_sw action mirred egress mirror dev swp2 action mirred egress mirror dev swp3
Error: mlxsw_spectrum: Multiple mirror actions per rule are not supported.

Internally, the sample action is implemented by the device by mirroring
to the CPU port. Therefore, mixing sample and mirror actions in a single
rule does not work correctly and results in the last action effect.
Solve by rejecting such misconfiguration:

The ice_copy_rxq_ctx_to_hw() and ice_write_rxq_ctx() functions perform some
defensive checks which are typically frowned upon by kernel style
guidelines.
In particular, NULL checks on buffers which point to the stack are
discouraged, especially when the functions are static and only called once.
Checks of this sort only serve to hide potential programming error, as we
will not produce the normal crash dump on a NULL access.
In addition, ice_copy_rxq_ctx_to_hw() cannot fail in another way, so could
be made void.
Future support for VF Live Migration will need to introduce an inverse
function for reading Rx queue context from HW registers to unpack it, as
well as functions to pack and unpack Tx queue context from HW.
Rather than copying these style issues into the new functions, lets first
cleanup the existing code.
For the ice_copy_rxq_ctx_to_hw() function:
* Move the Rx queue index check out of this function.
* Convert the function to a void return.
* Use a simple int variable instead of a u8 for the for loop index, and
initialize it inside the for loop.
* Update the function description to better align with kernel doc style.
For the ice_write_rxq_ctx() function:
* Move the Rx queue index check into this function.
* Update the function description with a Returns: to align with kernel doc
style.
These changes align the existing write functions to current kernel
style, and will align with the style of the new functions added when we
implement live migration in a future series.

The ice_write_rxq_ctx() function is responsible for programming the Rx
Queue context into hardware. It receives the configuration in unpacked form
via the ice_rlan_ctx structure.
This function unconditionally modifies the context to set the prefetch
enable bit. This was done by commit c31a5c25bb19 ("ice: Always set prefena
when configuring an Rx queue"). Setting this bit makes sense, since
prefetching descriptors is almost always the preferred behavior.
However, the ice_write_rxq_ctx() function is not the place that actually
defines the queue context. We initialize the Rx Queue context in
ice_setup_rx_ctx(). It is surprising to have the Rx queue context changed
by a function who's responsibility is to program the given context to
hardware.
Following the principle of least surprise, move the setting of the prefetch
enable bit out of ice_write_rxq_ctx() and into the ice_setup_rx_ctx().

The ice_rlan_ctx and ice_tlan_ctx structures have some fields which are
intentionally sized larger than necessary relative to the packed sizes the
data must fit into. This was done because the original ice_set_ctx()
function and its helpers did not correctly handle packing when the packed
bits straddled a byte. This is no longer the case with the use of the
<linux/packing.h> implementation.
Save some bytes in these structures by sizing the variables to the number
of bytes the actual bitpacked fields fit into.
There are a couple of gaps left in the structure, which is a result of the
fields being in the order they appear in the packed bit layout, but where
alignment forces some extra gaps. We could fix this, saving ~8 bytes from
each structure. However, these structures are not used heavily, and the
resulting savings is minimal:
$ bloat-o-meter ice-before-reorder.ko ice-after-reorder.ko
add/remove: 0/0 grow/shrink: 1/1 up/down: 26/-70 (-44)
Function old new delta
ice_vsi_cfg_txq 1873 1899 +26
ice_setup_rx_ctx.constprop 1529 1459 -70
Total: Before=1459555, After=1459511, chg -0.00%
Thus, the fields are left in the same order as the packed bit layout,
despite the gaps this causes.

The ice driver needs to write the Tx and Rx queue context when programming
Tx and Rx queues. This is currently done using some bespoke custom logic
via the ice_set_ctx() and its helper functions, along with bit position
definitions in the ice_tlan_ctx_info and ice_rlan_ctx_info structures.
This logic does work, but is problematic for several reasons:
1) ice_set_ctx requires a helper function for each byte size being packed,
as it uses a separate function to pack u8, u16, u32, and u64 fields.
This requires 4 functions which contain near-duplicate logic with the
types changed out.
2) The logic in the ice_pack_ctx_word, ice_pack_ctx_dword, and
ice_pack_ctx_qword does not handle values which straddle alignment
boundaries very well. This requires that several fields in the
ice_tlan_ctx_info and ice_rlan_ctx_info be a size larger than their bit
size should require.
3) Future support for live migration will require adding unpacking
functions to take the packed hardware context and unpack it into the
ice_rlan_ctx and ice_tlan_ctx structures. Implementing this would
require implementing ice_get_ctx, and its associated helper functions,
which essentially doubles the amount of code required.
The Linux kernel has had a packing library that can handle this logic since
commit 554aae35007e ("lib: Add support for generic packing operations").
The library was recently extended with support for packing or unpacking an
array of fields, with a similar structure as the ice_ctx_ele structure.
Replace the ice-specific ice_set_ctx() logic with the recently added
pack_fields and packed_field_s infrastructure from <linux/packing.h>
For API simplicity, the Tx and Rx queue context are programmed using
separate ice_pack_txq_ctx() and ice_pack_rxq_ctx(). This avoids needing to
export the packed_field_s arrays. The functions can pointers to the
appropriate ice_txq_ctx_buf_t and ice_rxq_ctx_buf_t types, ensuring that
only buffers of the appropriate size are passed.

The ice Tx and Rx queue context are currently stored as arrays of bytes
with defined size (ICE_RXQ_CTX_SZ and ICE_TXQ_CTX_SZ). The packed queue
context is often passed to other functions as a simple u8 * pointer, which
does not allow tracking the size. This makes the queue context API easy to
misuse, as you can pass an arbitrary u8 array or pointer.
Introduce wrapper typedefs which use a __packed structure that has the
proper fixed size for the Tx and Rx context buffers. This enables the
compiler to track the size of the value and ensures that passing the wrong
buffer size will be detected by the compiler.
The existing APIs do not benefit much from this change, however the
wrapping structures will be used to simplify the arguments of new packing
functions based on the recently introduced pack_fields API.

The int_q_state field of the ice_tlan_ctx structure represents the internal
queue state. However, we never actually need to assign this or read this
during normal operation. In fact, trying to unpack it would not be possible
as it is larger than a u64. Remove this field from the ice_tlan_ctx
structure, and remove its packing field from the ice_tlan_ctx_info array.

Most of the sanity checks in pack() and unpack() can be covered at
compile time. There is only one exception, and that is truncation of the
uval during a pack() operation.
We'd like the error-less __pack() to catch that condition as well. But
at the same time, it is currently the responsibility of consumer drivers
(currently just sja1105) to print anything at all when this error
occurs, and then discard the return code.
We can just print a loud warning in the library code and continue with
the truncated __pack() operation. In practice, having the warning is
very important, see commit 24deec6b9e4a ("net: dsa: sja1105: disallow
C45 transactions on the BASE-TX MDIO bus") where the bug was caught
exactly by noticing this print.
Add the first print to the packing library, and at the same time remove
the print for the same condition from the sja1105 driver, to avoid
double printing.

rtl_wq is allocated at rtl_init_core, so it makes more sense to destroy it
at rtl_deinit_core. In the case of USB, where _rtl_usb_init does not
require anything to be undone, that is fine. But for PCI, rtl_pci_init,
which is called after rtl_init_core, needs to deallocate data, but only if
it has been called.
That means that destroying the workqueue needs to be done whether
rtl_pci_init has been called or not. And since rtl_pci_deinit was doing it,
it has to be moved out of there.
It makes more sense to move it to rtl_deinit_core and have it done in both
cases, USB and PCI.
Since this is a requirement for a followup memory leak fix, mark this as
fixing such memory leak.

Commit 2461c7d60f9f ("rtlwifi: Update header file") introduced a global
list of private data structures.
Later on, commit 26634c4b1868 ("rtlwifi Modify existing bits to match
vendor version 2013.02.07") started adding the private data to that list at
probe time and added a hook, check_buddy_priv to find the private data from
a similar device.
However, that function was never used.
Besides, though there is a lock for that list, it is never used. And when
the probe fails, the private data is never removed from the list. This
would cause a second probe to access freed memory.
Remove the unused hook, structures and members, which will prevent the
potential race condition on the list and its corruption during a second
probe when probe fails.

returns directly if it isn't. In ML scenario where we have non-primary links created,
this results in leaking the michael_mic info since it is allocated by default but
could never be freed for a non-primary link.
Note that we can not move the might-sleep allocation after primary link check since
there we are in atomic context (due to spin lock). So keep the default allocation,
and then free it before return to fix this issue.

Currently the stop routine of rswitch driver does not immediately
prevent hardware from continuing to update descriptors and requesting
interrupts.
It can happen that when rswitch_stop() executes the masking of
interrupts from the queues of the port being closed, napi poll for
that port is already scheduled or running on a different CPU. When
execution of this napi poll completes, it will unmask the interrupts.
And unmasked interrupt can fire after rswitch_stop() returns from
napi_disable() call. Then, the handler won't mask it, because
napi_schedule_prep() will return false, and interrupt storm will
happen.
This can't be fixed by making rswitch_stop() call napi_disable() before
masking interrupts. In this case, the interrupt storm will happen if
interrupt fires between napi_disable() and masking.
Fix this by checking for priv->opened_ports bit when unmasking
interrupts after napi poll. For that to be consistent, move
priv->opened_ports changes into spinlock-protected areas, and reorder
other operations in rswitch_open() and rswitch_stop() accordingly.

If hardware is already transmitting, it can start handling the

field, before the queue is kicked by a write to GWTRC.
If the start_xmit() execution is preempted at unfortunate moment, this
transmission can complete, and interrupt handled, before gq->cur gets

When sending frame split into multiple descriptors, hardware processes
descriptors one by one, including writing back DT values. The first
descriptor could be already marked as completed when processing of
next descriptors for the same frame is still in progress.
Although only the last descriptor is configured to generate interrupt,
completion of the first descriptor could be noticed by the driver when
handling interrupt for the previous frame.
Currently, driver stores skb in the entry that corresponds to the first
descriptor. This results into skb could be unmapped and freed when
hardware did not complete the send yet. This opens a window for
corrupting the data being sent.
Fix this by saving skb in the entry that corresponds to the last
descriptor used to send the frame.
