tcp: improve delivered counts in SCM_TSTAMP_ACK

Currently delivered and delivered_ce in OPT_STATS of SCM_TSTAMP_ACK do
not fully reflect the current ack being timestamped. Also they are not
in sync as the delivered count includes packets being sacked and some of
cumulatively acked but delivered_ce includes none.

This patch series updates tp->delivered and tp->delivered_ce together to

tcp_clean_rtx_queue() to reflect packets being cumulatively acked up
until the current skb for sack-enabled connections.

mptcp: refactor token container

Currently the msk sockets are stored in a single radix tree, protected by a
global spin_lock. This series moves to an hash table, allocated at boot time,
with per bucker spin_lock - alike inet_hashtables, but using a different key:
the token itself.

The above improves scalability, as write operations will have a far later chance
to compete for lock acquisition, allows lockless lookup, and will allow
easier msk traversing - e.g. for diag interface implementation's sake.

This also introduces trivial, related, kunit tests and move the existing in
kernel's one to kunit.

Replace the radix tree with a hash table allocated
at boot time. The radix tree has some shortcoming:
a single lock is contented by all the mptcp operation,
the lookup currently use such lock, and traversing
all the items would require a lock, too.

With hash table instead we trade a little memory to
address all the above - a per bucket lock is used.

To hash the MPTCP sockets, we re-use the msk' sk_node
entry: the MPTCP sockets are never hashed by the stack.
Replace the existing hash proto callbacks with a dummy
implementation, annotating the above constraint.

Additionally refactor the token creation to code to:

- limit the number of consecutive attempts to a fixed
maximum. Hitting a hash bucket with a long chain is
considered a failed attempt

- accept() no longer can fail to token management.

- if token creation fails at connect() time, we do
fallback to TCP (before the connection was closed)

net: organize driver docs by device type

This series finishes off what I started in
commit b255e500 ("net: documentation: build a directory structure for drivers").
The objective is to de-clutter our documentation folder so folks
have a chance of finding relevant info. I _think_ I got all the
driver docs from the main documentation directory this time around.

While doing this I realized that many of them are of limited relevance
these days, so I went ahead and sliced the drivers directory by
technology. Those feeling nostalgic are free to dive into the FDDI,
ATM etc. docs, but for most Ethernet is what we care about.

Organize driver documentation by device type. Most documents
have fairly verbose yet uninformative names, so let users
first select a well defined device type, and then search for
a particular driver.

While at it rename the section from Vendor drivers to
Hardware drivers. This seems more accurate, besides people
sometimes refer to out-of-tree drivers as vendor drivers.

net: phy: relax PHY and MDIO reset handling

Previously these patches were submitted as part of a larger series[1]
but since the approach in it will have to be reworked I'm resending
the ones that were non-controversial and have been reviewed for upstream.

Florian suggested a better solution for managing multiple resets. While
I will definitely try to implement something at the driver model's bus
level (together with regulator support), the 'resets' and 'reset-gpios'
DT property is a stable ABI defined in mdio.yaml so improving its support
is in order as we'll have to stick with it anyway. Current implementation
contains an unnecessary limitation where drivers without probe() can't
define resets.

Changes from the previous version:
- order forward declarations in patch 4 alphabetically
- collect review tags

Similarily to PHY drivers - there's no reason to require probe() to be

Currently we only call phy_device_reset() if the PHY driver implements
the probe() callback. This is not mandatory and many drivers (e.g.
realtek) don't need probe() for most devices but still can have reset
GPIOs defined. There's no reason to depend on the presence of probe()
here so pull the reset code out of the if clause.
