By default Flow Control feature is not being enabled in stmmac.
This is a useful feature that can prevent loss of packets and now that
XGMAC already supports it (along with GMAC and QoS) it makes sense to
activate it.
Switch the module parameter to FLOW_AUTO so that Flow Control is
activated.

On platforms that lack a TCAM (like LS1088A), masking of
flow steering keys is not supported. Until now we didn't
offer flow steering capabilities at all on these platforms,
since our driver implementation configured a "comprehensive"
FS key (containing all supported header fields), with masks
used to ignore the fields not present in the rules provided
by the user.
We now allow ethtool rules that share a common key (i.e. have
the same header fields). The FS key is now kept in the driver
private data and initialized when the first rule is added to
an empty table, rather than at probe time. If a rule with a new
composition key is wanted, the user must first manually delete
all previous rules.
When building a FS table entry to pass to firmware, we still use
the old building algorithm, which assumes an all-supported-fields
key, and later collapse the fields which aren't actually needed.
Masked rules are not supported; if provided, the mask value
will be ignored. For firmware versions older than MC10.7.0
(that only offer the legacy ABIs for configuring distribution
keys) flow steering without masking support remains unavailable.

The Micrel KSZ9031 PHY may fail to establish a link when the Asymmetric
Pause capability is set. This issue is described in a Silicon Errata
(DS80000691D or DS80000692D), which advises to always disable the
capability. This patch implements the workaround by defining a KSZ9031
specific get_feature callback to force the Asymmetric Pause capability
bit to be cleared.
This fixes issues where the link would not come up at boot time, or when
the Asym Pause bit was set later on.

In the case where PTP is running on the hardware clock, but the kernel
system time is not being synced, a device reset can mess up the clock
time.
This occurs because we reset the clock time based on the kernel time
every reset. This causes us to potentially completely reset the PTP
time, and can cause unexpected behavior in programs like ptp4l.
Avoid this by saving the PTP time prior to device reset, and then
restoring using that time after the reset.
Directly restoring the PTP time we saved isn't perfect, because time
should have continued running, but the clock will essentially be stopped
during the reset. This is still better than the current solution of
assuming that the PTP HW clock is synced to the CLOCK_REALTIME.
We can do even better, by saving the ktime and calculating
a differential, using ktime_get(). This is based on CLOCK_MONOTONIC, and
allows us to get a fairly precise measure of the time difference between
saving and restoring the time.
Using this, we can update the saved PTP time, and use that as the value
to write to the hardware clock registers. This, of course is not perfect.
However, it does help ensure that the PTP time is restored as close as
feasible to the time it should have been if the reset had not occurred.
During device initialization, continue using the system time as the
source for the creation of the PTP clock, since this is the best known
current time source at driver load.

This patch introduces DDP (Dynamic Device Personalization) which allows
loading profiles that change the way internal parser interprets processed
frames. To load DDP profiles it utilizes ethtool flash feature. The files
with recipes must be located in /var/lib/firmware directory. Afterwards
the recipe can be loaded by invoking:
ethtool -f <if_name> <file_name> 100
ethtool -f <if_name> - 100
See further details of this feature in the i40e documentation, or
visit
https://www.intel.com/content/www/us/en/architecture-and-technology/ethernet/dynamic-device-personalization-brief.html
The driver shall verify DDP profile can be loaded in accordance with
the rules:
* Package with Group ID 0 are exclusive and can only be loaded the first.
* Packages with Group ID 0x01-0xFE can only be loaded simultaneously
with the packages from the same group.
* Packages with Group ID 0xFF are compatible with all other packages.

A merge flow is formed from 2 sub flows. The match fields of the merge are
the same as the first sub flow that has formed it, with the actions being
a combination of the first and second sub flow. Therefore, a merge flow
should replace sub flow 1 when offloaded.
Offload valid merge flows by using a new 'flow mod' message type to
replace an existing offloaded rule. Track the deletion of sub flows that
are linked to a merge flow and revert offloaded merge rules if required.

With the merging of 2 sub flows, a new 'merge' flow will be created and
written to FW. The TC layer is unaware that the merge flow exists and will
request stats from the sub flows. Conversely, the FW treats a merge rule
the same as any other rule and sends stats updates to the NFP driver.
Add links between merge flows and their sub flows. Use these links to pass
merge flow stats updates from FW to the underlying sub flows, ensuring TC
stats requests are handled correctly. The updating of sub flow stats is
done on (the less time critcal) TC stats requests rather than on FW stats
update.

When combining 2 sub_flows to a single 'merge flow' (assuming the merge is
valid), the merge flow should contain the same match fields as sub_flow 1
with actions derived from a combination of sub_flows 1 and 2. This action
list should have all actions from sub_flow 1 with the exception of the
output action that triggered the 'implicit recirculation' by sending to
an internal port, followed by all actions of sub_flow 2. Any pre-actions
in either sub_flow should feature at the start of the action list.
Add code to generate a new merge flow and populate the match and actions
fields based on the sub_flows. The offloading of the flow is left to
future patches.

Each flow is given a context ID that the fw uses (along with its cookie)
to identity the flow. The flows stats are updated by the fw via this ID
which is a reference to a pre-allocated array entry.
In preparation for flow merge code, enable the nfp_fl_payload structure to
be accessed via this stats context ID. Rather than increasing the memory
requirements of the pre-allocated array, add a new rhashtable to associate
each active stats context ID with its rule payload.
While adding new code to the compile metadata functions, slightly
restructure the existing function to allow for cleaner, easier to read

FW may receive a packet with its ingress port marked as an internal port.
If a rule does not exist to match on this port, the packet will be sent to
the NFP driver. Modify the flower app to detect packets from such internal
ports and convert the ingress port to the correct kernel space netdev.
At this point, it is assumed that fallback packets from internal ports are
to be sent out said port. Therefore, set the redir_egress bool to true on
detection of these ports.

Currently, it is assumed that fallback packets will be from reprs. Modify
this to allow an app to receive non-repr ports from the fallback channel -
e.g. from an internal port. If such a packet is received, do not update
repr stats.
Change the naming function calls so as not to imply it will always be a
repr netdev returned. Add the option to set a bool value to redirect a
fallback packet out the returned port rather than RXing it. Setting of
this bool in subsequent patches allows the handling of packets falling
back when they are due to egress an internal port.

Recent FW modifications allow the offloading of non repr ports. These
ports exist internally on the NFP. So if a rule outputs to an 'internal'
port, then the packet will recirculate back into the system but will now
have this internal port as it's incoming port. These ports are indicated
by a specific type field combined with an 8 bit port id.
Add private app data to assign additional port ids for use in offloads.
Provide functions to lookup or create new ids when a rule attempts to
match on an internal netdev - the only internal netdevs currently
supported are of type openvswitch. Have a netdev notifier to release
port ids on netdev unregister.
OvS offloads rules that match on internal ports as TC egress filters.
Ensure that such rules are accepted by the driver.

sk_forward_alloc's updating is also done on rx path, but to be consistent
we change to use sk_mem_charge() in sctp_skb_set_owner_r().
In sctp_eat_data(), it's not enough to check sctp_memory_pressure only,
which doesn't work for mem_cgroup_sockets_enabled, so we change to use
sk_under_memory_pressure().
When it's under memory pressure, sk_mem_reclaim() and sk_rmem_schedule()
should be called on both RENEGE or CHUNK DELIVERY path exit the memory
pressure status as soon as possible.
Note that sk_rmem_schedule() is using datalen to make things easy there.

Now when sending packets, sk_mem_charge() and sk_mem_uncharge() have been
used to set sk_forward_alloc. We just need to call sk_wmem_schedule() to
check if the allocated should be raised, and call sk_mem_reclaim() to
check if the allocated should be reduced when it's under memory pressure.
If sk_wmem_schedule() returns false, which means no memory is allowed to
allocate, it will block and wait for memory to become available.
Note different from tcp, sctp wait_for_buf happens before allocating any
skb, so memory accounting check is done with the whole msg_len before it
too.
