wifi: mac80211: mesh fast xmit support

Previously, fast xmit only worked on interface types where initially a
sta lookup is performed, and a cached header can be attached to the sta,
requiring only some fields to be updated at runtime.

This technique is not directly applicable for a mesh device type due
to the dynamic nature of the topology and protocol. There are more
addresses that need to be filled, and there is an extra header with a
dynamic length based on the addressing mode.

Change the code to cache entries contain a copy of the mesh subframe header +
bridge tunnel header, as well as an embedded struct ieee80211_fast_tx, which
contains the information for building the 802.11 header.

Add a mesh specific early fast xmit call, which looks up a cached entry and
adds only the mesh subframe header, before passing it over to the generic
fast xmit code.

To ensure the changes in network are reflected in these cached headers,
flush affected cached entries on path changes, as well as other conditions
that currently trigger a fast xmit check in other modes (key changes etc.)

This code is loosely based on a previous implementation by:

wifi: iwlwifi: mvm: Don't send MAC CTXT cmd after deauthorization

We used to send a MAC CTXT cmd to ask the FW to not pass MCAST frames
if we're associated but not authorized, because we don't have the
keys in that stage, and after authorization - we sent the cmd again
to ask the FW to pass MCAST, as we have the keys now.
The patch linked below was changing this strategy to always allow
MCAST frames, and if we're not authorized - the driver will drop them.
But we're still sending the MAC CTXT cmd after deaouthorization even
though we don't tell the FW to not pass MCAST frames anymore.
Basically we don't tell the FW anything new with this cmd.
Fix this by not sending MAC CTXT command after deauthorization.
For authorization we're sending the cmd to configure other changes too,
so keep it.

wifi: rtl8xxxu: Support new chip RTL8710BU aka RTL8188GU

This chip is found in cheap "free driver" USB adapters from Aliexpress.
Initially they pretend to be a CD-ROM containing the driver for Windows.
"Ejecting" switches the device to wifi mode.

Features: 2.4 GHz, b/g/n mode, 1T1R, 150 Mbps.

This chip is more unique than other Realtek chips:

* The registers at addresses 0x0-0xff, which all the other chips use,
  can't be used here. New registers at 0x8000-0x80ff must be used
  instead. And it's not a simple matter of adding 0x8000: 0x2
  (REG_SYS_FUNC) became 0x8004, 0x80 (REG_MCU_FW_DL) became 0x8090,
  etc.

* Also there are a few new registers which must be accessed indirectly
  because their addresses don't fit in 16 bits. No other chips seem to
  have these.

* The vendor driver compiles to 8188gu.ko, but the code calls the chip
  RTL8710B(U) pretty much everywhere, including messages visible to the
  user.

Another difference compared to the other chips supported by rtl8xxxu is
that it has a new PHY status struct, or three of them actually, from
which we extract the RSSI, among other things. This is not unique,
though, just new. The chips supported by rtw88 also use it.

Always run the entire init sequence (rtl8xxxu_init_device()) for

This fixes a bug where the device is unable to connect after
rebooting:

wlp3s0f3u2: send auth to ... (try 1/3)

Rebooting leaves the device powered on (partially? at least the

wifi: iwlwifi: fw: pnvm: fix uefi reduced TX power loading

There are a number of issues here:
 * if trans->reduce_power_loaded is already true, we call
   iwl_trans_set_reduce_power() with an uninitialized len
   value
 * in this case we also clobber a previous load/setting
 * if iwl_uefi_get_reduced_power() returns an ERR_PTR() we
   try to kfree() it

Move the iwl_trans_set_reduce_power() call into the success
case only to fix these issues.

wifi: iwlwifi: mvm: avoid sta lookup in queue alloc

In FW restart scenarios, we allocate the queues from the
iwl_mvm_realloc_queues_after_restart() function, but that
is called before we insert the station ID into our map
(mvm->fw_id_to_mac_id).

However, in all cases where we're actually allocating a
queue for a "real" (not bcast, aux, ...) station we have
the sta pointer already, so just pass it along to use it
instead of looking it up.

This fixes an issue where after restart we only allocated
a queue of size 16 (due to the ordering issue described
above), and thus never got good throughput again since no
aggregates could be formed on transmit.

wifi: ipw2x00: convert ipw_fw_error->elem to flexible array[]

The ipw_fw_error structure contains a payload[] flexible array as well as
two pointers to this array area, ->elem, and ->log. The total size of the
allocated structure is computed without use of the <linux/overflow.h>
macros.

There's no reason to keep both a payload[] and an extra pointer to both the
elem and log members. Convert the elem pointer member into the flexible
array member, removing payload.

Fix the allocation of the ipw_fw_error structure to use size_add(),
struct_size(), and array_size() to compute the allocation. This ensures
that any overflow saturates at SIZE_MAX rather than overflowing and
potentially allowing an undersized allocation.

Before the structure change, the layout of ipw_fw_error was:

struct ipw_fw_error {
        long unsigned int          jiffies;              /*     0     8 */
        u32                        status;               /*     8     4 */
        u32                        config;               /*    12     4 */
        u32                        elem_len;             /*    16     4 */
        u32                        log_len;              /*    20     4 */
        struct ipw_error_elem *    elem;                 /*    24     8 */
        struct ipw_event *         log;                  /*    32     8 */
        u8                         payload[];            /*    40     0 */

        /* size: 40, cachelines: 1, members: 8 */
        /* last cacheline: 40 bytes */
};

After this change, the layout is now:

struct ipw_fw_error {
        long unsigned int          jiffies;              /*     0     8 */
        u32                        status;               /*     8     4 */
        u32                        config;               /*    12     4 */
        u32                        elem_len;             /*    16     4 */
        u32                        log_len;              /*    20     4 */
        struct ipw_event *         log;                  /*    24     8 */
        struct ipw_error_elem      elem[];               /*    32     0 */

        /* size: 32, cachelines: 1, members: 7 */
        /* last cacheline: 32 bytes */
};

This saves a total of 8 bytes for every ipw_fw_error allocation, and
removes the risk of a potential overflow on the allocation.

To clean up drivers/net/wireless move the old drivers drivers left in the

CONFIG_WLAN_VENDOR_LEGACY like other vendors have but then dropped the idea as
these are really old drivers and hopefully we get to remove them soon.

====================
Rework SFP A2 access conditionals

This series reworks the SFP A2 (diagnostics and control) access so we
don't end up testing a variable number of conditions in several places.

This also resolves a minor issue where we may have a module indicating
that it is not SFF8472 compliant, doesn't implement A2, but fails to
set the enhanced option byte to zero, leading to accesses to the A2
page that fail.

The first patch adds a new flag "have_a2" which indicates whether we
should be accessing the A2 page, and uses this for hwmon. The
conditions are kept the same.

The second patch extends the check for soft-state polling and control
by using this "have_a2" flag (which effectively augments the check to
include some level of SFF8472 compliance.)

Provide the Ingress Stage 1 (IS1) VCAP (Versatile Content-Aware
Processor) support for the Lan966x platform.

The IS1 VCAP has 3 lookups and they are accessible with a TC chain id:
- chain 1000000: IS1 Lookup 0
- chain 1100000: IS1 Lookup 1
- chain 1200000: IS1 Lookup 2

The IS1 is capable of different actions like rewrite VLAN tags, change
priority of the frames, police the traffic, etc. These features will be
added at a later point.

The IS1 currently implements the action that allows setting the value
of a PAG (Policy Association Group) key field in the frame metadata and
this can be used for matching in an IS2 VCAP rule. In this way a rule in
IS0 VCAP can be linked to rules in the IS2 VCAP. The linking is exposed
by using the TC "goto chain" action with an offset from the IS2 chain ids.
For example "goto chain 8000001" will use a PAG value of 1 to chain to a
rule in IS2 lookup 0.

to calculate forward allocated memory compared to before. After
applied this patch, we could avoid receive path scheduling extra
amount of memory.

neigh_lookup_nodev isn't used in the kernel after removal
