rtw89: implement stop and resume channels transmission v1
These function is used to stop transmitting when we are going to switch
channels or do some RF calibration. Before these operations, we need to
stop channel transmission and backup setting into parameter tx_en. After
operations are done, resume transmitting by backup parameter tx_en.

mt7921s driver may receive frames with fragment buffers. If there is a
CTS packet received in monitor mode, the payload is 10 bytes only and
need 6 bytes header padding after RXD buffer. However, only RXD in the
first linear buffer, if we pull buffer size RXD-size+6 bytes with
skb_pull(), that would trigger "BUG_ON(skb->len < skb->data_len)" in
__skb_pull().
To avoid the nonlinear buffer issue, enlarge the RXD size from 128 to
256 to make sure all MCU operation in linear buffer.

The mcp251xfd chip doesn't support proper hardware based coalescing,
so this patch tries to implemented it in software. The RX-FIFO offers
a "FIFO not empty" interrupt, which is used if no coalescing is
active.
With activated RX IRQ coalescing the "FIFO not empty" interrupt is
disabled in the RX IRQ handler and the "FIFO half full" or "FIFO full
interrupt" (depending on RX max coalesced frames IRQ) is used instead.
To avoid RX CAN frame starvation a hrtimer is setup with RX coalesce
usecs IRQ,on timer expiration the "FIFO not empty" is enabled again.

ice: GTP support in switchdev
Marcin Szycik says:
Add support for adding GTP-C and GTP-U filters in switchdev mode.
To create a filter for GTP, create a GTP-type netdev with ip tool, enable
hardware offload, add qdisc and add a filter in tc:
ip link add $GTP0 type gtp role <sgsn/ggsn> hsize <hsize>
ethtool -K $PF0 hw-tc-offload on
tc qdisc add dev $GTP0 ingress
tc filter add dev $GTP0 ingress prio 1 flower enc_key_id 1337 \
action mirred egress redirect dev $VF1_PR
By default, a filter for GTP-U will be added. To add a filter for GTP-C,
specify enc_dst_port = 2123, e.g.:
tc filter add dev $GTP0 ingress prio 1 flower enc_key_id 1337 \
enc_dst_port 2123 action mirred egress redirect dev $VF1_PR
Note: outer IPv6 offload is not supported yet.
Note: GTP-U with no payload offload is not supported yet.
ICE COMMS package is required to create a filter as it contains GTP
profiles.
Changes in iproute2 [1] are required to be able to add GTP netdev and use
GTP-specific options (QFI and PDU type).

net: usb: asix: suspend embedded PHY if external is used
In case external PHY is used, we need to take care of embedded PHY.
Since there are no methods to disable this PHY from the MAC side and
keeping RMII reference clock, we need to suspend it.
This patch will reduce electrical noise (PHY is continuing to send FLPs)
and power consumption by 0,22W.

net: add per-cpu storage and net->core_stats
Before adding yet another possibly contended atomic_long_t,
it is time to add per-cpu storage for existing ones:
dev->tx_dropped, dev->rx_dropped, and dev->rx_nohandler
Because many devices do not have to increment such counters,
allocate the per-cpu storage on demand, so that dev_get_stats()
does not have to spend considerable time folding zero counters.
Note that some drivers have abused these counters which
were supposed to be only used by core networking stack.
v4: should use per_cpu_ptr() in dev_get_stats() (Jakub)
v3: added a READ_ONCE() in netdev_core_stats_alloc() (Paolo)
v2: add a missing include (reported by kernel test robot <lkp@intel.com>)

Merge branch 'nfp-preliminary-support-for-nfp-3800'
Simon Horman says:
====================
nfp: preliminary support for NFP-3800
This series is the first step to add support to the NFP driver for the
new NFP-3800 device. In this first series the goal is to clean
up small issues found while adding support for the new device, prepare
an abstraction of the differences between the already supported devices
and the new Kestrel device and add the new PCI ID.
* Patch 1/11 and 2/11 starts by removing some dead code and incorrect
assumptions found while working Kestrel support. Patch 3/11, 4/11 and
5/11 cleans up and prepares for adding the new PCI ID for Kestrel.
* Patches 6/11, 7/11, 8/11, 9/11, 10/11 adds, plumb and populates a device
information structure to abstract the differences between the existed
supported devices (NFP-4000, NFP-5000 and NFP-6000) and the
new device (NFP3800).
* Finally patch 11/11 adds the new PCI ID for Kestrel.
More work is needed to drive the new NFP-3800 device after this first
batch of patches the foundation is prepared for the follow up work.
Thanks to the work of all those who contributed to this work.

nfp: parametrize QCP offset/size using dev_info
The queue controller (QCP) is accessed based on a device specific
offset. The NFP3800 device also supports more queues.
Furthermore, the NFP3800 VFs also access the QCP differently to how the
NFP6000 VFs accesses it, though still indirectly. Fortunately, we can
remove the offset all together for both VF types. This is safe for
NFP6000 VFs since the offset was effectively a wrap around and only used
for convenience to have it set the same as the NFP6000 PF.
Use nfp_dev_info to store queue controller parameters.

nfp: remove pessimistic NFP_QCP_MAX_ADD limits
Multiple writes cause intermediate pointer values that do not
end on complete TX descriptors.
The QCP peripheral on the NFP provides a number of access
modes. In some access modes, the maximum amount to add must
be restricted to a 6bit value. The particular access mode
used by _nfp_qcp_ptr_add() has no such restrictions, so the
"< NFP_QCP_MAX_ADD" test is unnecessary.
Note that trying to add more that the configured ring size
in a single add will cause a QCP overflow, caught and handled
by the QCP peripheral.
