Adaptive-rx and Adaptive-tx are interrupt moderation settings
that can be enabled/disabled using ethtool:
ethtool -C ethX adaptive-rx on/off adaptive-tx on/off
Unfortunately those settings are getting cleared after
changing number of queues, or in ethtool world 'channels':
ethtool -L ethX rx 1 tx 1
Clearing was happening due to introduction of bit fields
in ice_ring_container struct. This way only itr_setting
bits were rebuilt during ice_vsi_rebuild_set_coalesce().
Introduce an anonymous struct of bitfields and create a
union to refer to them as a single variable.
This way variable can be easily saved and restored.

The hardware statistics counters are not cleared during resets so the
drivers first access is to initialize the baseline and then subsequent
reads are for reporting the counters. The statistics counters are read
during the watchdog subtask when the interface is up. If the baseline
is not initialized before the interface is up, then there can be a brief
window in which some traffic can be transmitted/received before the
initial baseline reading takes place.
Directly initialize ethtool statistics in driver open so the baseline will
be initialized when the interface is up, and any dropped packets
incremented before the interface is up won't be reported.

The design of INT indicator register (R_AX_PCIE_HIMR00_V1) is to reduce IO
during frequent interrupts, because it can stop chip sending interrupt to
host if we just set this indicator to 0, not all IMR(s). This indicator
register looks like a root interrupt controller of wifi chip.
However, we can't set all other IMR(s) to 0 during we are running on
interrupt service routine, or the indicator register can't reflect the
status of certain interrupt happened during this period, and then miss
some interrupts especially SER interrupt events.

In vmxnet3_rq_create(), when dma_alloc_coherent() fails,
vmxnet3_rq_destroy() is called. It sets rq->rx_ring[i].base to NULL. Then
vmxnet3_rq_create() returns an error to its callers mxnet3_rq_create_all()
-> vmxnet3_change_mtu(). Then vmxnet3_change_mtu() calls
vmxnet3_force_close() -> dev_close() in error handling code. And the driver
calls vmxnet3_close() -> vmxnet3_quiesce_dev() -> vmxnet3_rq_cleanup_all()
-> vmxnet3_rq_cleanup(). In vmxnet3_rq_cleanup(),
rq->rx_ring[ring_idx].base is accessed, but this variable is NULL, causing
a NULL pointer dereference.
To fix this possible bug, an if statement is added to check whether
rq->rx_ring[0].base is NULL in vmxnet3_rq_cleanup() and exit early if so.
The error log in our fault-injection testing is shown as follows:

one given to the object that holds an netdev when ifdown in many places of
ipv4 and ipv6 since commit 8d7017fd62 ("blackhole_netdev: use
blackhole_netdev to invalidate dst entries").
Especially after commit faab39f63c ("net: allow out-of-order netdev

freed before other netdev.
This patch is to set dst dev to blackhole_netdev instead of loopback_dev

The following two scenarios were failing for lan966x.
1. If the port had the address X and then trying to assign the same
address, then the HW was just removing this address because first it
tries to learn new address and then delete the old one. As they are
the same the HW remove it.
2. If the port eth0 was assigned the same address as one of the other
ports eth1 then when assigning back the address to eth0 then the HW
was deleting the address of eth1.
The case 1. is fixed by checking if the port has already the same
address while case 2. is fixed by checking if the address is used by any
other port.

skb_data_area_size() is not needed. As Jakub pointed out [1]:
For Rx, drivers can use the size passed during skb allocation or
use skb_tailroom().
For Tx, drivers should use skb_headlen().

====================
mptcp: Updates for net-next
Three independent fixes/features from the MPTCP tree:
Patch 1 is a selftest workaround for older iproute2 packages.
Patch 2 removes superfluous locks that were added with recent MP_FAIL
patches.
Patch 3 adds support for the TCP_DEFER_ACCEPT sockopt.

Two issues were observed in the ReST doc added by commit c3a0addefb
("docs: ctucanfd: CTU CAN FD open-source IP core documentation.")
with Sphinx versions 2.4.4 and 4.5.0.
The plain "figure" directive broke "make pdfdocs" due to a missing
PDF figure. For conversion of SVG -> PDF to work, the "kernel-figure"
directive, which is an extension for kernel documentation, should
be used instead.
The directive of "code:: raw" causes a warning from both
"make htmldocs" and "make pdfdocs", which reads:
[...]/can/ctu/ctucanfd-driver.rst:75: WARNING: Pygments lexer name
'raw' is not known
A plain literal-block marker should suffice where no syntax
highlighting is intended.
Fix the issues by using suitable directive and marker.

positive values, so perform the math with set_normalized_timespec().

Make the interrupt-names properties a required property, to make it
easier to identify the individual interrupts.

The CTU CAN-FD IP core is only useful when used with one of the
corresponding PCI/PCIe or platform (FPGA, SoC) drivers, which depend on
PCI resp. OF.
Hence make the users select the core driver code, instead of letting
then depend on it. Keep the core code config option visible when
compile-testing, to maintain compile-coverage.

Commit 3ea566422c ("can: isotp: sanitize CAN ID checks in
isotp_bind()") checks the given CAN ID address information by
sanitizing the input values.
This check (silently) removes obsolete bits by masking the given CAN
IDs.
Derek Will suggested to give a feedback to the application programmer
when the 'sanitizing' was actually needed which means the programmer
provided CAN ID content in a wrong format (e.g. SFF CAN IDs with a CAN
ID > 0x7FF).

Usually the ISO 15765-2 protocol is a point-to-point protocol to transfer
segmented PDUs to a dedicated receiver. This receiver sends a flow control
message to specify protocol options and timings (e.g. block size / STmin).
The so called functional addressing communication allows a 1:N
communication but is limited to a single frame length.
This new CAN_ISOTP_CF_BROADCAST allows an unconfirmed 1:N communication
with PDU length that would not fit into a single frame. This feature is
not covered by the ISO 15765-2 standard.

This patch calls into sock_cmsg_send() to parse the user supplied
control information into a struct sockcm_cookie. Then assign the
requested transmit time to the skb.
This makes it possible to use the Earliest TXTIME First (ETF) packet
scheduler with the CAN_RAW protocol. The user can send a CAN_RAW frame
with a TXTIME and the kernel (with the ETF scheduler) will take care
of sending it to the network interface.

The skb in raw_sendmsg() is allocated with sock_alloc_send_skb(),
which subsequently calls sock_alloc_send_pskb() -> skb_set_owner_w(),
which assigns "skb->sk = sk".
This patch removes the not needed setting of skb->sk.
