4f4925a7b2 iwlwifi: pcie: fix support for transmitting SKBs with fraglist
When the implementation of SKBs with fraglist was sent upstream, a
merge-damage occurred and half the patch was not applied.

This causes problems in high-throughput situations with AX200 devices,
including low throughput and FW crashes.

Introduce the part that was missing from the original patch.

3dff7c6e37 rtw88: allows to enable/disable HCI link PS mechanism
Different interfaces have its own link-related power save mechanism.
Such as PCI can enter L1 state based on the traffic on the link, and
sometimes driver needs to enable/disable it to avoid some issues, like
throughput degrade when PCI trying to enter L1 state even if driver is
having heavy traffic.

For now, rtw88 only supports PCIE chips, and they just need to disable
ASPM L1 when driver is not in power save mode, such as IPS and LPS.

d2e2c47e65 rtw88: pci: enable CLKREQ function if host supports it
By Realtek's design, there are two HW modules associated for CLKREQ,
one is responsible to follow the PCIE host settings, and another
is to actually working on it. But the module that is actually working
on it is default disabled, and driver should enable that module if
host and device have successfully sync'ed with each other.

The module is default disabled because sometimes the host does not
support it, and if there is any incorrect settings (ex. CLKREQ# is
not Bi-Direction), device can be lost and disconnected to the host.

So driver should first check after host and device are sync'ed, and
the host does support the function and set it in configuration
space, then driver can turn on the HW module to working on it.

decfc5c70d qtnfmac: track broadcast domain of each interface
If firmware reports that it supports hardware switch capabilities,
driver needs to track and notify device whenever broadcast domain
of a particular network device changes (ie. whenever it's upper
master device changes).

Firmware needs a unique ID to tell broadcast domains from each other
which is an opaque number otherwise. For that purpose we can use
netspace:ifidx pair to uniquely identify each broadcast domain:
 - if netdev is not part of a bridge, then use it's own ifidx
   as a broadcast domain ID
 - if netdev is part of a bridge, then use bridge netdev ifidx
   as broadcast domain ID

Firmware makes sure that packets are only forwarded between
interfaces marked with the same broadcast domain ID.

df98be06c9 bonding: symmetric ICMP transmit
A bonding with layer2+3 or layer3+4 hashing uses the IP addresses and the ports
to balance packets between slaves. With some network errors, we receive an ICMP
error packet by the remote host or a router. If sent by a router, the source IP
can differ from the remote host one. Additionally the ICMP protocol has no port
numbers, so a layer3+4 bonding will get a different hash than the previous one.
These two conditions could let the packet go through a different interface than
the other packets of the same flow:

    # tcpdump -qltnni veth0 |sed 's/^/0: /' &
    # tcpdump -qltnni veth1 |sed 's/^/1: /' &
    # hping3 -2 192.168.0.2 -p 9
    0: IP 192.168.0.1.2251 > 192.168.0.2.9: UDP, length 0
    1: IP 192.168.0.2 > 192.168.0.1: ICMP 192.168.0.2 udp port 9 unreachable, length 36
    1: IP 192.168.0.1.2252 > 192.168.0.2.9: UDP, length 0
    1: IP 192.168.0.2 > 192.168.0.1: ICMP 192.168.0.2 udp port 9 unreachable, length 36
    1: IP 192.168.0.1.2253 > 192.168.0.2.9: UDP, length 0
    1: IP 192.168.0.2 > 192.168.0.1: ICMP 192.168.0.2 udp port 9 unreachable, length 36
    0: IP 192.168.0.1.2254 > 192.168.0.2.9: UDP, length 0
    1: IP 192.168.0.2 > 192.168.0.1: ICMP 192.168.0.2 udp port 9 unreachable, length 36

An ICMP error packet contains the header of the packet which caused the network
error, so inspect it and match the flow against it, so we can send the ICMP via
the same interface of the previous packet in the flow.
Move the IP and port dissect code into a generic function bond_flow_ip() and if
we are dissecting an ICMP error packet, call it again with the adjusted offset.

4214fa1eff net: mscc: ocelot: omit error check from of_get_phy_mode
The commit 0c65b2b90d ("net: of_get_phy_mode: Change API to solve
int/unit warnings") updated the function of_get_phy_mode declaration.
Now it returns an error code and in case the node doesn't contain the
property 'phy-mode' or 'phy-connection-type' it returns -EINVAL and would
set the phy_interface_t to PHY_INTERFACE_MODE_NA.

Ocelot VSC7514 has 4 internal phys which have the phy interface
PHY_INTERFACE_MODE_NA. So because of_get_phy_mode would assign
PHY_INTERFACE_MODE_NA to phy_mode when there is an error, there is no need
to add the error check.

Updates for v2:
 - drop error check because of_get_phy_mode already assigns phy_interface
   to PHY_INTERFACE_MODE in case of error.

c3f812cea0 page_pool: do not release pool until inflight == 0.
The page pool keeps track of the number of pages in flight, and
it isn't safe to remove the pool until all pages are returned.

Disallow removing the pool until all pages are back, so the pool
is always available for page producers.

Make the page pool responsible for its own delayed destruction
instead of relying on XDP, so the page pool can be used without
the xdp memory model.

When all pages are returned, free the pool and notify xdp if the
pool is registered with the xdp memory system.  Have the callback
perform a table walk since some drivers (cpsw) may share the pool
among multiple xdp_rxq_info.

Note that the increment of pages_state_release_cnt may result in
inflight == 0, resulting in the pool being released.
