The tso_bytes and tso_inner_bytes counters currently subtract the header
length from skb->len, counting only the payload. This is confusing and
doesn't align with the behavior of other _bytes counters in the driver.
Report the full skb length to align with this expectation.

The hardware has two sets of registers controlling TX/RX flow control.
The effective flow control state is determined by the logical OR of
these two sets of bits.
RTASE_FORCE_TXFLOW_EN and RTASE_FORCE_RXFLOW_EN in RTASE_CPLUS_CMD are
the bits used by the driver to control TX/RX flow control according to
the ethtool pause configuration.
RTASE_TXFLOW_EN and RTASE_RXFLOW_EN in RTASE_GPHY_STD_00 are another
set of TX/RX flow control enable bits. Clear them by default so they do
not keep flow control enabled independently of the driver setting.
With the RTASE_GPHY_STD_00 bits cleared, the effective flow control
state is controlled through RTASE_CPLUS_CMD, so the ethtool setting can
take effect correctly.

- Verify peer availability before transmission by checking committed
DW schedule or FAW of the peer schedule.
RX path:

Add all the handling to do NAN synchronization on 2.4 GHz including
sending out beacons. With this, the mac80211_hwsim NAN device also works
when used in conjunction with an external medium simulation.
Note that the TSF sync is not ideal in case of an external medium
simulation. This is because the mactime for received frames needs to be
estimated and the simulation may not update the timestamp of beacons
to the actual time that the frame was transmitted.
The implementation has an initial short phase where it scans for
clusters. This facilitates cluster joining and avoids creating a new
cluster immediately, which would result in two cluster join
notifications. It does not scan otherwise and will only see another
cluster appearing if a discovery beacon happens to be sent during the
2.4 GHz discovery window (DW).

Frames submitted on the NAN device interface should only be transmitted
during one of the discovery windows (DWs). It is assumed that software
submits frames from the DW end notifications for the next DW period.
Simulate this behaviour by checking that we are currently in a DW before
transmitting from ieee80211_hwsim_wake_tx_queue. As frames will be
queued up at the start of a DW, wake the management TX queue every time
a DW is started. Do so with a randomized offset just to avoid every
client transmitting at the same time.

The RX path allocations for rxbufs_pre, das_pre, and rxq scale with
queue count and queue depth. With high queue counts and depth, these can
exceed what kmalloc can reliably provide from physically contiguous
memory under fragmentation.
Switch these from kmalloc to kvmalloc variants so the allocator
transparently falls back to vmalloc when contiguous memory is scarce,
and update the corresponding frees to kvfree.

Convert tx_qp from a single contiguous array allocation to per-queue
individual allocations. Each mana_tx_qp struct is approximately 35KB.
With many queues (e.g., 32/64), the flat array requires a single
contiguous allocation that can fail under memory fragmentation.
Change mana_tx_qp *tx_qp to mana_tx_qp **tx_qp (array of pointers),
allocating each queue's mana_tx_qp individually via kvzalloc. This
reduces each allocation to ~35KB and provides vmalloc fallback,
avoiding allocation failure due to fragmentation.

None of the udp_tunnel users need struct socket in their
fast paths; it is only used for tunnel setup / teardown.
While the UDP tunnel interface accepts struct socket, this
encourages users to store the pointer unnecessarily. This
leads to extra dereferences when accessing struct sock fields
(e.g., sk->sk_user_data instead of sock->sk->sk_user_data).
Furthermore, these dereferences necessitate synchronize_rcu()
in udp_tunnel_sock_release() to protect the fast paths from
sock_orphan() setting sk->sk_socket to NULL.
This overhead can be avoided if users store the struct sock
pointer directly in their private structures.
As a prep, let's change udp_tunnel_sock_release() to take
struct sock instead of struct socket.

Introduce support for continuous ranging and advanced timing
parameters in the FTM request, response, and capability paths.
This enables more flexible ranging scenarios with improved control
over measurement timing and session management.

Document the MDIO interface topology with an ASCII diagram
showing the MAC, PCS (MMD 3), FEC, Separated PMA (MMD 8), and PMD
(MMD 1) blocks and their interconnects. The diagram illustrates how
4 lanes connect the MAC through PCS, FEC, and PMA, then narrow to
2 lanes at the PMD.
The c45 read and write routines are enhanced to support
read and write of the separated PMA for the fbnic.

Consolidate the register reads for boiler plate registers
to reduce LOC and cleanup pcs reads for DEVS1 to
fetch overrides for reserved bits that the hardware does not
return.

Currently the remain_on_channel operation does not support
filtering incoming frames by destination MAC address. This
prevents use cases such as PASN authentication in the
responder side that need to receive frames addressed to a
specific MAC during the off-channel period.
Add an rx_addr parameter to the remain_on_channel operation
callback and propagate it through the call chain from nl80211
to driver implementations. Introduce the extended feature
NL80211_EXT_FEATURE_ROC_ADDR_FILTER as a capability gate so
that cfg80211 rejects the request if the driver does not
advertise support for address filtering. Extract the address
from the NL80211_ATTR_MAC attribute when provided in the
netlink message and update the tracing infrastructure to
include the address in remain_on_channel trace events. The
rx_addr parameter is optional and can be NULL, maintaining
backward compatibility with existing drivers.

Simply immediately TX all available packets on the corresponding queue.
This removes the HWSIM_TM_CMD_STOP_QUEUES/HWSIM_TM_CMD_RESUME_QUEUES
feature for now. It should be reasonably simple to add it back if it is
needed.

Refactor the NAN timer to more closely track the where in the NAN
schedule the device currently is. Do this by having an hrtimer that
fires at the start of every slot.
For now continue to update the current channel at the start of the DW.
In the future, the correct channel according to the schedule should be
used everywhere.
This is in preparation to more accurately simulate more of the NAN
logic.

It is easy to calculate the next target beacon transmission time (TBTT)
based on the current TSF and the beacon interval. Use this method to
calculate the time to the next beacon.
With this, the bcn_delta variable can be removed and drift over time due
to the timer firing late is fully avoided.

By delegating writing the timestamp into beacons and probe responses, we
can remove the abs_bcn_ts from the global data and still avoid any time
offset issues. This also seems conceptually closer to "real" hardware
where the timestamp will be written late in the TX path.
Move sending the SKB to the monitor interface to happen later, so that
the frame timestamp has the value filled in by mac80211_hwsim.
