We face the issue that link change interrupt and link status may be
reported by different PHY layers. As a result the link change
interrupt may occur before the link status changes.
Export phy_queue_state_machine to allow PHY drivers to specify a
delay between link status change interrupt and link status check.

The phylib interrupt handler handles link change events only currently.
However PHY drivers may want to use other interrupt sources too,
e.g. to report temperature monitoring events. Therefore add a callback
to struct phy_driver allowing PHY drivers to implement a custom
interrupt handler.

This patch is a step towards allowing PHY drivers to handle more
interrupt sources than just link change. E.g. several PHY's have
built-in temperature monitoring and can raise an interrupt if a
temperature threshold is exceeded. We may be interested in such
interrupts also if the phylib state machine isn't started.
Therefore move enabling interrupts to phy_request_interrupt().

In case a call to dsa_tree_setup() fails, an attempt to cleanup is made
by calling dsa_tree_remove_switch(), which should take care of
removing/unregistering any resources previously allocated. This does not
happen because it is conditioned by dst->setup being true, which is set
only after _all_ setup steps were performed successfully.
This is especially interesting when the internal MDIO bus is registered
but afterwards, a port setup fails and the mdiobus_unregister() is never
called. This leads to a BUG_ON() complaining about the fact that it's
trying to free an MDIO bus that's still registered.
Add proper error handling in all functions branching from
dsa_tree_setup().

This patch is a further step towards decoupling firmware handling from
the actual driver code. Firmware can be for PHY and/or MAC, and two
pairs of read/write functions are needed for handling PHY firmware and
MAC firmware respectively. Pass these functions via struct rtl_fw and
avoid the ugly switching of mdio_ops behind the back of rtl_writephy().

Commit 283c16a2dfd3 ("indirect call wrappers: helpers to speed-up
indirect calls of builtin") introduces some macros to avoid doing
indirect calls.
Use these helpers to remove two indirect calls in the L4 checksum
calculation for devices which don't have hardware support for it.
As a test I generate packets with pktgen out to a dummy interface
with HW checksumming disabled, to have the checksum calculated in
every sent packet.
The packet rate measured with an i7-6700K CPU and a single pktgen
thread raised from 6143 to 6608 Kpps, an increase by 7.5%

This patch enables IPv4 and IPv6 conntrack from the bridge to deal with
local traffic. Hence, packets that are passed up to the local input path
are confirmed later on from the {ipv4,ipv6}_confirm() hooks.
For packets leaving the IP stack (ie. output path), fragmentation occurs
after the inet postrouting hook. Therefore, the bridge local out and
postrouting bridge hooks see fragments with conntrack objects, which is
inconsistent. In this case, we could defragment again from the bridge
output hook, but this is expensive. The recommended filtering spot for
outgoing locally generated traffic leaving through the bridge interface
is to use the classic IPv4/IPv6 output hook, which comes earlier.

This patch adds basic connection tracking support for the bridge,
including initial IPv4 support.
This patch register two hooks to deal with the bridge forwarding path,
one from the bridge prerouting hook to call nf_conntrack_in(); and
another from the bridge postrouting hook to confirm the entry.
The conntrack bridge prerouting hook defragments packets before passing
them to nf_conntrack_in() to look up for an existing entry, otherwise a
new entry is allocated and it is attached to the skbuff. The conntrack
bridge postrouting hook confirms new conntrack entries, ie. if this is
the first packet seen, then it adds the entry to the hashtable and (if
needed) it refragments the skbuff into the original fragments, leaving
the geometry as is if possible. Exceptions are linearized skbuffs, eg.
skbuffs that are passed up to nfqueue and conntrack helpers, as well as
cloned skbuff for the local delivery (eg. tcpdump), also in case of
bridge port flooding (cloned skbuff too).
The packet defragmentation is done through the ip_defrag() call. This
forces us to save the bridge control buffer, reset the IP control buffer
area and then restore it after call. This function also bumps the IP
fragmentation statistics, it would be probably desiderable to have
independent statistics for the bridge defragmentation/refragmentation.
The maximum fragment length is stored in the control buffer and it is
used to refragment the skbuff from the postrouting path.
The new fraglist splitter and fragment transformer APIs are used to
implement the bridge refragmentation code. The br_ip_fragment() function
drops the packet in case the maximum fragment size seen is larger than
the output port MTU.
This patchset follows the principle that conntrack should not drop
packets, so users can do it through policy via invalid state matching.
Like br_netfilter, there is no refragmentation for packets that are
passed up for local delivery, ie. prerouting -> input path. There are
calls to nf_reset() already in several spots in the stack since time ago
already, eg. af_packet, that show that skbuff fraglist handling from the
netif_rx path is supported already.
The helpers are called from the postrouting hook, before confirmation,
from there we may see packet floods to bridge ports. Then, although
unlikely, this may result in exercising the helpers many times for each
clone. It would be good to explore how to pass all the packets in a list
to the conntrack hook to do this handle only once for this case.
Thanks to Florian Westphal for handing me over an initial patchset
version to add support for conntrack bridge.

This patch exposes a new API to refragment a skbuff. This allows you to
split either a linear skbuff or to force the refragmentation of an
existing fraglist using a different mtu. The API consists of:
* ip6_frag_init(), that initializes the internal state of the transformer.
* ip6_frag_next(), that allows you to fetch the next fragment. This function
internally allocates the skbuff that represents the fragment, it pushes
the IPv6 header, and it also copies the payload for each fragment.
The ip6_frag_state object stores the internal state of the splitter.
This code has been extracted from ip6_fragment(). Symbols are also
exported to allow to reuse this iterator from the bridge codepath to
build its own refragmentation routine by reusing the existing codebase.

Add support for get/set of an optional backup key via TCP_FASTOPEN_KEY, in
addition to the current 'primary' key. The primary key is used to encrypt
and decrypt TFO cookies, while the backup is only used to decrypt TFO
cookies. The backup key is used to maximize successful TFO connections when
TFO keys are rotated.
Currently, TCP_FASTOPEN_KEY allows a single 16-byte primary key to be set.
This patch now allows a 32-byte value to be set, where the first 16 bytes
are used as the primary key and the second 16 bytes are used for the backup
key. Similarly, for getsockopt(), we can receive a 32-byte value as output
if requested. If a 16-byte value is used to set the primary key via
TCP_FASTOPEN_KEY, then any previously set backup key will be removed.

We would like to be able to rotate TFO keys while minimizing the number of
client cookies that are rejected. Currently, we have only one key which can
be used to generate and validate cookies, thus if we simply replace this
key clients can easily have cookies rejected upon rotation.
We propose having the ability to have both a primary key and a backup key.
The primary key is used to generate as well as to validate cookies.
The backup is only used to validate cookies. Thus, keys can be rotated as:
1) generate new key
2) add new key as the backup key
3) swap the primary and backup key, thus setting the new key as the primary
We don't simply set the new key as the primary key and move the old key to
the backup slot because the ip may be behind a load balancer and we further
allow for the fact that all machines behind the load balancer will not be
updated simultaneously.
We make use of this infrastructure in subsequent patches.

The driver core first registers with the hwmon and thermal subsystems
and only then proceeds to initialize the switch driver (e.g.,
mlxsw_spectrum). It is only during the last stage that the current
firmware version is validated and a newer one flashed, if necessary.
The above means that if a new firmware feature is utilized by the
hwmon/thermal code, the driver will not be able to load.
Solve this by re-ordering initializing the switch driver before
registering with the hwmon and thermal subsystems.

The smp_store_release call in fqdir_exit cannot protect the setting
of fqdir->dead as claimed because its memory barrier is only
guaranteed to be one-way and the barrier precedes the setting of
fqdir->dead.
IOW it doesn't provide any barriers between fq->dir and the following
hash table destruction.
In fact, the code is safe anyway because call_rcu does provide both
the memory barrier as well as a guarantee that when the destruction
work starts executing all RCU readers will see the updated value for
fqdir->dead.
Therefore this patch removes the unnecessary smp_store_release call
as well as the corresponding READ_ONCE on the read-side in order to
not confuse future readers of this code. Comments have been added
in their places.

This allows drivers to lookup i2c adapters on ACPI based systems similar to
of_get_i2c_adapter_by_node() with DT based systems.

This patch mostly capitalizes abbreviations in code comments. Fixed some
typos and removed some unnecessary newlines as well.

In ice_print_link_msg, add cases for 50GB and 100GB speeds. This
results in the right speed being reported on load, instead of
"Unknownbps".
When VF link if forced (in ice_set_pfe_link_forced), report
max speed 100GB.

Replace the use of the ICE_DBG_AQ_MSG bit when dumping firmware logging
messages with a separate distinct type ICE_DBG_FW_LOG. This is useful
so that developers may enable ICE_DBG_FW_LOG and get firmware logging
messages, without also dumping AdminQ messages at the same time.

The current specification has updates to the command formats for
manage MAC opcodes (opcodes 0x0107 and 0x0108) and get PHY caps
(opcode 0x0600). Update the code to reflect this.
