We have plans for increasing MAX_SKB_FRAGS, but sk_msg_sg::copy
is currently an unsigned long, limiting MAX_SKB_FRAGS to 30 on 32bit arches.
Convert it to a bitmap, as Jakub suggested.

Instead of disabling TSO at compile time if MAX_SKB_FRAGS > 32,
implement ndo_features_check() method for this driver for
a more dynamic handling.
If skb has more than 32 frags and is a GSO packet, force
software segmentation.
Most locally generated packets will use a small number
of fragments anyway.
For forwarding workloads, we can limit gro_max_size at ingress,
we might also implement gro_max_segs if needed.

It seems this one-element array is not actually being used as an
array of variable size, so we can just replace it with just a
non-array object of type struct desc_frag and refactor a bit the
rest of the code.
This helps with the ongoing efforts to globally enable -Warray-bounds
and get us closer to being able to tighten the FORTIFY_SOURCE routines
on memcpy().
This issue was found with the help of Coccinelle and audited and fixed,
manually.

There is a regular need in the kernel to provide a way to declare having
a dynamically sized set of trailing elements in a structure. Kernel code
should always use “flexible array members”[1] for these cases. The older
style of one-element or zero-length arrays should no longer be used[2].

net: device tracking improvements
Main goal of this series is to be able to detect the following case
which apparently is still haunting us.
dev_hold_track(dev, tracker_1, GFP_ATOMIC);
dev_hold(dev);
dev_put(dev);
dev_put(dev); // Should complain loudly here.
dev_put_track(dev, tracker_1); // instead of here (as before this series)

We are still chasing some syzbot reports where we think a rogue dev_put()
is called with no corresponding prior dev_hold().
Unfortunately it eats a reference on dev->dev_refcnt taken by innocent
dev_hold_track(), meaning that the refcount saturation splat comes
too late to be useful.
Make sure that 'not tracked' dev_put() and dev_hold() better use
CONFIG_NET_DEV_REFCNT_TRACKER=y debug infrastructure:
Prior patch in the series allowed ref_tracker_alloc() and ref_tracker_free()
to be called with a NULL @trackerp parameter, and to use a separate refcount
only to detect too many put() even in the following case:
dev_hold_track(dev, tracker_1, GFP_ATOMIC);
dev_hold(dev);
dev_put(dev);
dev_put(dev); // Should complain loudly here.
dev_put_track(dev, tracker_1); // instead of here
Add clarification about netdev_tracker_alloc() role.
v2: I replaced the dev_put() in linkwatch_do_dev()
with __dev_put() because callers called netdev_tracker_free().

This patch implemented a new function named pm_nl_set_endpoint(), wrapped
the PM netlink commands 'ip mptcp endpoint change flags' and 'pm_nl_ctl
set flags' in it, and used a new argument 'ip_mptcp' to choose which one

'ip mptcp' used the ID number argument to find out the address to change
flags, while 'pm_nl_ctl' used the address and port number arguments. So
we need to parse the address ID from the PM dump output as well as the
address and port number.

The insertion frequency is represented as "k/n", meaning IOAM will be
added to {k} packets over {n} packets, with 0 < k <= n and 1 <= {k,n} <=
1000000. Therefore, it provides the following percentages of insertion
frequency: [0.0001% (min) ... 100% (max)].
Not only this solution allows an operator to apply dynamic frequencies
based on the current traffic load, but it also provides some
flexibility, i.e., by distinguishing similar cases (e.g., "1/2" and
"2/4").
"1/2" = Y N Y N Y N Y N ...
"2/4" = Y Y N N Y Y N N ...

net: ipa: improve RX buffer replenishing
This series revises the algorithm used for replenishing receive
buffers on RX endpoints. Currently there are two atomic variables
that track how many receive buffers can be sent to the hardware.
The new algorithm obviates the need for those, by just assuming we
always want to provide the hardware with buffers until it can hold
no more.
The first patch eliminates an atomic variable that's not required.
The next moves some code into the main replenish function's caller,
making one of the called function's arguments unnecessary. The
next six refactor things a bit more, adding a new helper function
that allows us to eliminate an additional atomic variable. And the
final two implement two more minor improvements.

Rather than tracking the number of receive buffer transactions that
have been submitted without a doorbell, just track the total number
of transactions that have been issued. Then ring the doorbell when
that number modulo the replenish batch size is 0.
The effect is roughly the same, but the new count is slightly more
interesting, and this approach will someday allow the replenish
batch size to be tuned at runtime.

When replenishing, have ipa_endpoint_replenish() allocate a
transaction, and pass that to ipa_endpoint_replenish_one() to fill.
Then, if that produces no error, commit the transaction within the
replenish loop as well. In this way we can distinguish between
transaction failures and buffer allocation/mapping failures.
Failure to allocate a transaction simply means the hardware already
has as many receive buffers as it can hold. In that case we can
break out of the replenish loop because there's nothing more to do.
If we fail to allocate or map pages for the receive buffer, just
try again later.

A transaction failure only occurs if no more transactions are
