The Synopsys TSN MAC supports Qbv base times in the past, but only up to a
certain limit. As a result, a taprio qdisc configuration with a small
base time (for example when treating the base time as a simple phase
offset) is not applied by the hardware and silently ignored.
This was observed on an NXP i.MX8MPlus device, but likely affects all
TSN-variants of the MAC.
Fix the issue by making sure the base time is in the future, pushing it by
an integer amount of cycle times if needed. (a similar check is already
done in several other taprio implementations, see for example
drivers/net/ethernet/intel/igc/igc_tsn.c#L116 or
drivers/net/dsa/sja1105/sja1105_ptp.h#L39).

When configuring a 802.1Qbv schedule through the tc taprio qdisc on an NXP
i.MX8MPlus device, the effective cycle time differed from the requested one
by N*96ns, with N number of entries in the Qbv Gate Control List. This is
because the driver was adding a 96ns margin to each interval of the GCL,
apparently to account for the IPG. The problem was observed on NXP
i.MX8MPlus devices but likely affected all devices relying on the same
configuration callback (dwmac 4.00, 4.10, 5.10 variants).
Fix the issue by removing the margins, and simply setup the MAC with the
provided cycle time value. This is the behavior expected by the user-space
API, as altering the Qbv schedule timings would break standards conformance.
This is also the behavior of several other Ethernet MAC implementations
supporting taprio, including the dwxgmac variant of stmmac.

Since the original mtu is not used when the mtu is updated,
the mtu is aligned with cache, this will get an incorrect.
For example, if you want to configure the mtu to be 1500,
but mtu 1536 is configured in fact.

TID stuck is seen when there is a race in
CPL_PASS_ACCEPT_RPL/CPL_ABORT_REQ and abort is arriving
before the accept reply, which sets the queue number.
In this case HW ends up sending CPL_ABORT_RPL_RSS to an
incorrect ingress queue.

- Removed the unused variable len in chtls_set_quiesce_ctrl().
V2->V3:
- As kfree_skb() has a check for null skb, so removed this

Currently, the function i40e_construct_skb_zc only frees the input xdp
buffer when the output skb is successfully built. On error, the
function i40e_clean_rx_irq_zc does not commit anything for the current
packet descriptor and simply exits the packet descriptor processing
loop, with the plan to restart the processing of this descriptor on
the next invocation. Therefore, on error the ring next-to-clean
pointer should not advance, the xdp i.e. *bi buffer should not be
freed and the current buffer info should not be invalidated by setting
*bi to NULL. Therefore, the *bi should only be set to NULL when the
function i40e_construct_skb_zc is successful, otherwise a NULL *bi
will be dereferenced when the work for the current descriptor is
eventually restarted.

Use of __napi_schedule_irqoff() is not safe with PREEMPT_RT in which
hard interrupts are not disabled while running the threaded interrupt.
Using __napi_schedule() works for both PREEMPT_RT and mainline Linux,
just at the cost of an additional check if interrupts are disabled for
mainline (since they are already disabled).
Similar to the fix done for enetc commit 215602a8d212 ("enetc: use

The function bnxt_get_ulp_stat_ctxs() does not count the stats contexts
used by the RDMA driver correctly when the RDMA driver is freeing the
MSIX vectors. It assumes that if the RDMA driver is registered, the
additional stats contexts will be needed. This is not true when the
RDMA driver is about to unregister and frees the MSIX vectors.
This slight error leads to over accouting of the stats contexts needed
after the RDMA driver has unloaded. This will cause some firmware
warning and error messages in dmesg during subsequent config. changes
or ifdown/ifup.
Fix it by properly accouting for extra stats contexts only if the
RDMA driver is registered and MSIX vectors have been successfully
requested.

This commit enables the use of the r8153_ecm driver, introduced with
commit c1aedf015ebdd0 ("net/usb/r8153_ecm: support ECM mode for
RTL8153") for the Lenovo Powered USB-C Hub (17ef:721e) based on the
Realtek RTL8153B chip.
This results in the following driver preference:
- if r8152 is available, use the r8152 driver
- if r8152 is not available, use the r8153_ecm driver
This is done to prevent the NIC from constantly sending pause frames
when the host system enters standby (fixed by using the r8152 driver
in "r8152: Add Lenovo Powered USB-C Travel Hub"), while still allowing
the device to work with the r8153_ecm driver as a fallback.

This USB-C Hub (17ef:721e) based on the Realtek RTL8153B chip used to
use the cdc_ether driver. However, using this driver, with the system
suspended the device constantly sends pause-frames as soon as the
receive buffer fills up. This causes issues with other devices, where
some Ethernet switches stop forwarding packets altogether.
Using the Realtek driver (r8152) fixes this issue. Pause frames are no
longer sent while the host system is suspended.

Increase critical threshold for ASIC thermal zone from 110C to 140C
according to the system hardware requirements. All the supported ASICs
(Spectrum-1, Spectrum-2, Spectrum-3) could be still operational with ASIC
temperature below 140C. With the old critical threshold value system
can perform unjustified shutdown.
All the systems equipped with the above ASICs implement thermal
protection mechanism at firmware level and firmware could decide to
perform system thermal shutdown in case the temperature is below 140C.
So with the new threshold system will not meltdown, while thermal
operating range will be aligned with hardware abilities.

For all PCI functions on the netxen_nic adapter, interrupt
mode (INTx or MSI) configuration is dependent on what has
been configured by the PCI function zero in the shared
interrupt register, as these adapters do not support mixed
mode interrupts among the functions of a given adapter.
Logic for setting MSI/MSI-x interrupt mode in the shared interrupt
register based on PCI function id zero check is not appropriate for
all family of netxen adapters, as for some of the netxen family
adapters PCI function zero is not really meant to be probed/loaded
in the host but rather just act as a management function on the device,
which caused all the other PCI functions on the adapter to always use
legacy interrupt (INTx) mode instead of choosing MSI/MSI-x interrupt mode.
This patch replaces that check with port number so that for all
type of adapters driver attempts for MSI/MSI-x interrupt modes.

When setting up a channel bridge, ppp_bridge_channels sets the
pch->bridge field before taking the associated reference on the bridge
file instance.
This opens up a refcount underflow bug if ppp_bridge_channels called
via. iotcl runs concurrently with ppp_unbridge_channels executing via.
file release.
The bug is triggered by ppp_bridge_channels taking the error path
through the 'err_unset' label. In this scenario, pch->bridge is set,
but the reference on the bridged channel will not be taken because
the function errors out. If ppp_unbridge_channels observes pch->bridge
before it is unset by the error path, it will erroneously drop the
reference on the bridged channel and cause a refcount underflow.
To avoid this, ensure that ppp_bridge_channels holds a reference on
each channel in advance of setting the bridge pointers.

At the moment it is quite hard to identify the network interface
provided by IPA in userspace components: The network interface is
created as virtual device, without any link to the IPA device.
The interface name ("rmnet_ipa%d") is the only indication that the
network interface belongs to IPA, but this is not very reliable.
Add SET_NETDEV_DEV() to associate the network interface with the
IPA parent device. This allows userspace services like ModemManager
to properly identify that this network interface is provided by IPA
and belongs to the modem.

Adding vf VLANID for the first time, or after having cleared previously
defined VLANID works fine, however, attempting to change an existing vf
VLANID clears the rules on the firmware, but does not add new rules for
the new vf VLANID.
Fix this by changing the logic in function esw_acl_egress_lgcy_setup()
so that it will always configure egress rules.

The previous patch fixes a TEF vs. TX race condition, by first updating the TEF
tail pointer in hardware, and then updating the driver internal pointer.
The same pattern exists in the RX-path, too. This should be no problem, as the
driver accesses the RX-FIFO from the interrupt handler only, thus the access is
properly serialized. Fix the order here, too, so that the TEF- and RX-path look
similar.

The mcp251xfd driver uses a TX FIFO for sending CAN frames and a TX Event FIFO
(TEF) for completed TX-requests.
The TEF event handling in the mcp251xfd_handle_tefif() function has a race
condition. It first increments the tx-ring's tail counter to signal that
there's room in the TX and TEF FIFO, then it increments the TEF FIFO in
hardware.
A running mcp251xfd_start_xmit() on a different CPU might not stop the txqueue
(as the tx-ring still shows free space). The next mcp251xfd_start_xmit() will
push a message into the chip and the TX complete event might overflow the TEF
FIFO.
This patch changes the order to fix the problem.

According to the TCAN4550 datasheet "SLLSF91 - DECEMBER 2018" the tcan4x5x has
the same bittiming constants as a m_can revision 3.2.x/3.3.0.
The tcan4x5x chip I'm using identifies itself as m_can revision 3.2.1, so
remove the tcan4x5x specific bittiming values and rely on the values in the
m_can driver, which are selected according to core revision.
