Commit 3c783b83 ("net: dsa: mv88e6xxx: get rid of SPEED_MAX setting")
stopped relying on SPEED_MAX constant and hardcoded speed settings
for the switch ports and rely on phylink configuration.

It turned out, however, that when the relevant code is called,
the mac_capabilites of CPU/DSA port remain unset.
mv88e6xxx_setup_port() is called via mv88e6xxx_setup() in
dsa_tree_setup_switches(), which precedes setting the caps in
phylink_get_caps down in the chain of dsa_tree_setup_ports().

As a result the mac_capabilites are 0 and the default speed for CPU/DSA
port is 10M at the start. To fix that, execute mv88e6xxx_get_caps()
and obtain the capabilities driectly.

net: dsa: microchip: add support for phylink mac config and link up

This patch series add support common phylink mac config and link up for the ksz
series switches. At present, ksz8795 and ksz9477 doesn't implement the phylink
mac config and link up. It configures the mac interface in the port setup hook.

Some group of switches have some register address and bit fields common and
others are different. So, this patch aims to have common phylink implementation
which configures the register based on the chip id.

tls: rx: decrypt from the TCP queue

This is the final part of my TLS Rx rework. It switches from
strparser to decrypting data from skbs queued in TCP. We don't
need the full strparser for TLS, its needs are very basic.
This set gives us a small but measurable (6%) performance
improvement (continuous stream).
====================

Link: https://lore.kernel.org/r/20220722235033.2594446-1-kuba@kernel.orgSigned-off-by: Jakub Kicinski <kuba@kernel.org>

TLS is a relatively poor fit for strparser. We pause the input
every time a message is received, wait for a read which will
decrypt the message, start the parser, repeat. strparser is
built to delineate the messages, wrap them in individual skbs
and let them float off into the stack or a different socket.
TLS wants the data pages and nothing else. There's no need
for TLS to keep cloning (and occasionally skb_unclone()'ing)
the TCP rx queue.

This patch uses a pre-allocated skb and attaches the skbs
from the TCP rx queue to it as frags. TLS is careful never
to modify the input skb without CoW'ing / detaching it first.

Since we call TCP rx queue cleanup directly we also get back
the benefit of skb deferred free.

Overall this results in a 6% gain in my benchmarks.

Wrap the remaining skb_cow_data() into a helper, so it's easier

so make sure relevant pointers get reloaded after the call.
Signed-off-by: Jakub Kicinski <kuba@kernel.org>

Expose TCP rx queue accessor and cleanup, so that TLS can
decrypt directly from the TCP queue. The expectation
is that the caller can access the skb returned from
tcp_recv_skb() and up to inq bytes worth of data (some
of which may be in ->next skbs) and then call
tcp_read_done() when data has been consumed.
The socket lock must be held continuously across
those two operations.
Signed-off-by: Jakub Kicinski <kuba@kernel.org>

The non-zero-copy path assumes a full skb with decrypted contents.
This means the device offload would have to CoW the data. Try
to keep the zero-copy status instead, copy the data to user space.
Signed-off-by: Jakub Kicinski <kuba@kernel.org>

In the future we'll want to reuse the input skb in case of
zero-copy so we shouldn't always free darg.skb. Move the
freeing of darg.skb into the non-zc cases. All cases will
now free ctx->recv_pkt (inside let tls_rx_rec_done()).
Signed-off-by: Jakub Kicinski <kuba@kernel.org>

After recent changes the SW side of tls_rx_one_record() can
be nicely encapsulated in its own function. Move the pad handling
as well. This will be useful for ->zc handling in tls_decrypt_device().

Implement dev info and dev flash for line cards

This patchset implements two features:
1) "devlink dev info" is exposed for line card (patches 6-9)
2) "devlink dev flash" is implemented for line card gearbox
   flashing (patch 10)

For every line card, "a nested" auxiliary device is created which
allows to bind the features mentioned above (patch 4).

The relationship between line card and its auxiliary dev devlink
is carried over extra line card netlink attribute (patches 3 and 5).

The first patch removes devlink_mutex from devlink_register/unregister()
which eliminates possible deadlock during devlink reload command. The
second patchset follows up with putting net pointer check into new
helper.
