Unlike the legacy EEPROM callbacks, when using the netlink EEPROM query
(get_module_eeprom_by_page) the driver should not try to validate the
query parameters, but just perform the read requested by the userspace.

The assumption that the first byte in the module mapping dword is the
module number shouldn't be hard-coded in the driver, but come from
mlx5_ifc structs.
While at it, fix the incorrect width for the 'rx_lane' and 'tx_lane'
fields.

SMFS dr matchers are processed sequentially in hardware according to
their priorities, and not skipped if empty.
Currently, smfs ct fs creates four predefined dr matchers per ct
table (ct/ct nat) with hardcoded priority. Compared to dmfs ct fs
using autogroups, this might cause additional hops in fastpath for
traffic patterns that match later priorties, even if previous
priorites are empty, e.g user only using ipv6 UDP traffic will
have additional 3 hops.
Create the matchers dynamically, using the highest priority available,
on first rule usage, and remove them on last usage.

fs_core layer adds extra book keeping that is either unneeded for CT, or
unused by the underlying software steering, such as allocating FTEs and
FTE ids, saving the match key and mask, and autogroups management.
On top of that, direct steering has a translation layer (fs_dr) from PRM
commands to direct steering objects, for example, creating temporary
dr_action objects. This has a performance impact when dealing
with CT high insertion rate.
To use direct steering (smfs) directly for ct, add a tc ct fs smfs
implementation. Instead of dmfs autogroups, smfs ct fs uses one of 4
predefined dr matchers in CT and CT-NAT tables, for each combination
of tuple ethertype (ipv4/ipv6), and tuple ip_proto (udp/tcp) that
is currently used by nf flow table flow offload.
At rule insertions, validate the flow rule fits one of the predfined
matcher, and insert to it.
To fill the dr_actions of the rule efficiently, create the fwd to post_ct
tbl dr_action at fs init, the count dr_action at counter creation,
and re-use the already pre-allocated modify header dr_action.

If sw steering was used to create the table, dr steeering fs creates
a backing dr table for the mlx5 flow table.
Add helper to return this table so it can be used to create matchers and
add rules on it directly instead of passing via eswitch_offloads/fs_core
insertion.

Currently, fs_core layer provides flow steering services to the driver
including: autogroups, allocating FTEs (flow table entries) and FTE ids,
and support of fte action modification. If then software steering is
configured, rule insertion will go through a translation layer from
firmware buffers to software steering objects (see fs_dr.c).
The connection tracking table is a system table that is not directly
controlled by the user and is a very high scale table. These fs_core
services introduces an overhead that may be optimized by using software
steering API directly.
Introduce ct flow steering interface to allow multiple flow steering
providers. Use the new interface to implement the current dmfs (device
managed flow steering) provider which uses fs_core insertion.

The serial port driver attempts to test for correct THRE behavior
on startup. However, it does this by disabling interrupts, and
then intentionally trying to trigger an interrupt in order to see
if the IIR bit is set in the UART.
However, in this FPGA design, the UART interrupt is generated
through the MSI vector, so when interrupts are re-enabled after
the test, the DMAR-IR reports an unhandled IRTE entry, since
no irq handler is installed at this point - it is installed
after the test.
This only happens on the /second/ open of the UART, since on the
first open, the x86_vector has installed and activated by the
driver probe, and is correctly handled. When the serial port is
closed for the first time, this vector is deactivated and removed,
leading to this error.

Previous commits introduced AF_XDP zero-copy support, in which
we need register different mem model for xdp_rxq when AF_XDP
zero-copy is enabled or not. And this should be done after xdp_rxq
info is registered, which is not needed for ctrl port, otherwise
there complaints warnings: "Missing register, driver bug".
Fix this by not registering mem model for ctrl port, just like we
don't register xdp_rxq info for ctrl port.

This enables non-standard MTUs on a per-port basis, with the overall
frame size set based on the CPU port.
When the MTU is not changed, this should have no effect.
Long packets crash the switch with MTUs of greater than 2526, so the
maximum is limited for now. Medium packets are sometimes dropped (e.g.
TCP over 2477, UDP over 2516-2519, ICMP over 2526), Hence an MTU value
of 2400 seems safe.

Commit 5dbbbd01cbba83 ("ice: Avoid RTNL lock when re-creating

so ice_plug_aux_dev() is called from ice_service_task() context.
This unfortunately opens a race window that can result in dead-lock
when interface has left LAG and immediately enters LAG again.
Reproducer:
```
#!/bin/sh
ip link add lag0 type bond mode 1 miimon 100
ip link set lag0
for n in {1..10}; do
echo Cycle: $n
ip link set ens7f0 master lag0
sleep 1
ip link set ens7f0 nomaster
done
```

1. Command 'ip link ... set nomaster' causes that ice_plug_aux_dev()
is called from ice_service_task() context, aux device is created
and associated device->lock is taken.
2. Command 'ip link ... set master...' calls ice's notifier under
RTNL lock and that notifier calls ice_unplug_aux_dev(). That
function tries to take aux device->lock but this is already taken
by ice_plug_aux_dev() in step 1
3. Later ice_plug_aux_dev() tries to take RTNL lock but this is already
taken in step 2
4. Dead-lock
The patch fixes this issue by following changes:
- Bit ICE_FLAG_PLUG_AUX_DEV is kept to be set during ice_plug_aux_dev()
call in ice_service_task()
- The bit is checked in ice_clear_rdma_cap() and only if it is not set
then ice_unplug_aux_dev() is called. If it is set (in other words
plugging of aux device was requested and ice_plug_aux_dev() is
potentially running) then the function only clears the bit
- Once ice_plug_aux_dev() call (in ice_service_task) is finished
the bit ICE_FLAG_PLUG_AUX_DEV is cleared but it is also checked
whether it was already cleared by ice_clear_rdma_cap(). If so then
aux device is unplugged.

Sometimes the link comes up but no data flows. This patch fixes
this behavior. It's not clear what's the root cause of the issue.
According to the tests one other link-up issue remains.
In very rare cases the link isn't even reported as up.

Some of the bcmgenet platforms don't correctly support WOL, yet
ethtool returns:
"Supports Wake-on: gsf"
which is false.
Ideally if there isn't a wol_irq, or there is something else that
keeps the device from being able to wakeup it should display:
"Supports Wake-on: d"
This patch checks whether the device can wakup, before using the
hard-coded supported flags. This corrects the ethtool reporting, as
well as the WOL configuration because ethtool verifies that the mode
is supported before attempting it.

If bus->state is equal to MDIOBUS_ALLOCATED, mdiobus_free(bus) will free
the "bus". But bus->name is still used in the next line, which will lead
to a use after free.
We can fix it by putting the name in a local variable and make the
bus->name point to the rodata section "name",then use the name in the
error message without referring to bus to avoid the uaf.

mlx5-updates-2022-03-09
1) Remove kernel log prints on FW events regarding FW pages management
and replace that with debugfs entries to track FW pages management commands
failures and general stats, we do that for all FW commands in general since
it's the same effort to do so under the already existing debugfs entry for
FW commands.
2) Add support for ConnectX-7 Software managed steering, in other words STEv2
which shares a lot in common with STE V1, the difference is in specific
offsets in the devices, the logic is almost the same, thus we implement
STEv1 and STEv2 in the same file.

This works around an issue with the hardware where both OE and
DAT are exposed in the same register. If both are updated
simultaneously, the harware makes no guarantees that OE or DAT
will actually change in any given order and may result in a
glitch of a few ns on a GPIO pin when changing direction and value
in a single write.
Setting direction to input now only affects OE bit. Setting
direction to output updates DAT first, then OE.

The CANtact Pro from LinkLayer Labs is based on the LPC54616 µC, which
is affected by the NXP LPC USB transfer erratum. However, the current
firmware (version 2) doesn't set the
GS_CAN_FEATURE_REQ_USB_QUIRK_LPC546XX bit.
This patch sets the feature GS_CAN_FEATURE_REQ_USB_QUIRK_LPC546XX to
workaround this issue.
For the GS_USB_BREQ_DATA_BITTIMING USB control message the CANtact Pro
firmware uses a request value, which is already used by the
candleLight firmware for a different purpose
(GS_USB_BREQ_GET_USER_ID).
This patch set the feature GS_CAN_FEATURE_QUIRK_BREQ_CANTACT_PRO to
workaround this issue.

Introduce a workaround for a NXP chip errata on LPC546xx
controllers (Errata sheet LPC546xx / USB.15).
According to the document corruption can occur when the following
conditions are met:
* A TX (IN) transfer happens after a RX (OUT) transfer.
* The RX (OUT) transfer length is 4 + N * 16 (N >= 0) bytes.
Even though the struct gs_host_frame has a size of 76 bytes for a FD
frame, which does not apply to the above rule, corruption could be
seen.
Adding a dummy byte to break the second condition also on transfer
lengths with 4 + N * 8 bytes reliably circumvents USB transfer data
corruption.
The firmware can now request this quirk by setting
GS_CAN_FEATURE_REQ_USB_QUIRK_LPC546XX.

CANtact Pro from Linklayer is the first gs_usb compatible device
supporting CAN-FD with a different HW and re-written candlelight FW.
Support for CAN-FD is indicated by the device setting the
GS_CAN_FEATURE_FD flag. CAN-FD support is requested by the driver with
the GS_CAN_MODE_FD flag. The CAN-FD specific data bit timing
parameters are set with the GS_USB_BREQ_DATA_BITTIMING control
message.
This patch is based on the Eric Evenchick's gs_usb_fd driver (which
itself is a fork of gs_usb). The gs_usb_fd code base was reintegrated
into the gs_usb driver, and reworked to not break the existing
classical-CAN only hardware.
