do_tcp_sendpages() is now just a small wrapper around tcp_sendmsg_locked(),

Add layer 4 RSS hashing on UDP traffic to allow for the
utilization of multiple queues for multiple connections on

Previously, since the introduction of the driver, RSS hashing
was only performed on the source and destination IP addresses
of UDP packets thereby limiting UDP traffic to a single queue
for multiple connections on the same IP address. The transport
layer is now included in RSS hashing for UDP traffic, which
was not previously the case. The reason behind the previous

Parse all meta data in the same place where protocol type fields are
parsed. Add description for the currently implemented meta data. It is
important to note that depending on DDP not all described meta data can
be available. Using not available meta data leads to error returned by
function which is looking for correct words in profiles read from DDP.

ice: use src VSI instead of src MAC in slow-path
The use of a source MAC to direct packets from the VF to the corresponding
port representor is only ok if there is only one MAC on a VF. To support
this functionality when the number of MACs on a VF is greater, it is
necessary to match a source VSI instead of a source MAC.
Let's use the new switch API that allows matching on metadata.
If MAC isn't used in match criteria there is no need to handle adding
rule after virtchnl command. Instead add new rule while port representor
is being configured.
Remove rule_added field, checking for sp_rule can be used instead.
Remove also checking for switchdev running in deleting rule as it can be
called from unroll context when running flag isn't set. Checking for
sp_rule covers both context (with and without running flag).
Rules are added in eswitch configuration flow, so there is no need to

ice: allow matching on meta data
Add meta data matching criteria in the same place as protocol matching
criteria. There is no need to add meta data as special words after
parsing all lookups. Trade meta data in the same why as other lookups.
The one difference between meta data lookups and protocol lookups is
that meta data doesn't impact how the packets looks like. Because of that
ignore it when filling testing packet.
Match on tunnel type meta data always if tunnel type is different than
TNL_LAST.

ice: remove redundant Rx field from rule info
Information about the direction is currently stored in sw_act.flag.
There is no need to duplicate it in another field.
Setting direction flag doesn't mean that there is a match criteria for
direction in rule. It is only a information for HW from where switch id
should be collected (VSI or port). In current implementation of advance
rule handling, without matching for direction meta data, we can always
set one the same flag and everything will work the same.
Ability to match on direction meta data will be added in follow up

criteria, but they are handled in other function.

Russell King says:
====================
net: sfp: add support for control of rate selection
This series introduces control of the rate selection SFP pins (or
their soft state in the I2C diagnostics EEPROM). Several SNIA documents
(referenced in the commits) describe the various different modes for
these, and we implement them all for maximum compatibility, but as
we know, SFP modules tend to do their own thing, so that may not be
sufficient.
In order to implement this, we need to change the locking arrangement
in the SFP layer - we need to make st_mutex (state mutex) able to be
taken from within the rtnl lock and sm_mutex (state machine mutex).
Essentially, st_mutex protects the hard (gpio) and soft state signals.
So, patches 2 through 5 rejig the locking so that st_mutex is only
ever taken when we want to fiddle with the signal state variables,
read or write the GPIOs, or read or write the soft state.
Patch 1 adds a helper that makes the locking rejig a little easier
as it combines the update of sfp->state with setting the updated
control state to the module.
Patch 6 adds code to phylink to give the signalling rate for various
PHY interface modes that are relevant to SFPs - this is the baud rate
of the encoded signal, not the data rate, which is what matters for
SFPs. This rate is passed through the SFP bus layer into the SFP
socket driver, which initially has a stub sfp_set_signal_rate().
Patch 7 adds the code to the SFP socket driver to parse the rate
selection data in the EEPROM, configure which RS signals need to be
driven, and the signalling rate threshold. We fill in
sfp_set_signal_rate() to set the rate select pins as appropriate.

net: lan966x: Add support for DSCP rewrite
Add support for DSCP rewrite in lan966x driver. On egress DSCP is
rewritten from either classified DSCP, or frame DSCP. Classified DSCP is
determined by the Analyzer Classifier on ingress, and is mapped from
classified QoS class and DP level. Classification of DSCP is by default
enabled for all ports.
It is required that DSCP is trusted for the egress port *and* rewrite
table is not empty, in order to rewrite DSCP based on classified DSCP,
otherwise DSCP is always rewritten from frame DSCP.

Its currently not allowed to perform queries on a map, for example:
table t {
map m {
typeof ip saddr : meta mark
..
chain c {
ip saddr @m counter
will fail, because kernel requires that userspace provides a destination
register when the referenced set is a map.
However, internally there is no real distinction between sets and maps,
maps are just sets where each key is associated with a value.
Relax this so that maps can be used just like sets.
This allows to have rules that query if a given key exists
without making use of the associated value.
This also permits != checks which don't work for map lookups.
When no destination reg is given for a map, then permit this for named
maps.
Data and dump paths need to be updated to consider priv->dreg_set
instead of the 'set-is-a-map' check.
Checks in reduce and validate callbacks are not changed, this
can be relaxed later if a need arises.

behind this combination of tests.
But that causes a warning when building with CONFIG_TRACING_BRANCHES,
since that sets DISABLE_BRANCH_PROFILING for the tracing code, and the
declaration is thus hidden:
kernel/trace/trace_branch.c:205:6: error: no previous prototype for 'ftrace_likely_update' [-Werror=missing-prototypes]
Move the declaration out of the #ifdef to avoid the warning.

ice: Remove LAG+SRIOV mutual exclusion
There was a change previously to stop SR-IOV and LAG from existing on the
same interface. This was to prevent the violation of LACP (Link
Aggregation Control Protocol). The method to achieve this was to add a
no-op Rx handler onto the netdev when SR-IOV VFs were present, thus
blocking bonding, bridging, etc from claiming the interface by adding
its own Rx handler. Also, when an interface was added into a aggregate,
then the SR-IOV capability was set to false.
There are some users that have in house solutions using both SR-IOV and
bridging/bonding that this method interferes with (e.g. creating duplicate
VFs on the bonded interfaces and failing between them when the interface
fails over).
It makes more sense to provide the most functionality
possible, the restriction on co-existence of these features will be
removed. No additional functionality is currently being provided beyond
what existed before the co-existence restriction was put into place. It is
up to the end user to not implement a solution that would interfere with
existing network protocols.

ice: update PHY type to ethtool link mode mapping
Some link modes can be more accurately reported due to newer link mode
values that have been added to the kernel; update those PHY type to report
modes that better reflect the link mode.
