In STEv1 counter action can be set either by filling counter ID on STE, in
which case it is executed before other actions on this STE, or as a single
action, in which case it is executed in accordance with the actions order.
FW steering on STEv1 devices implements counter as counter ID on STE, and
this counter is set on the last STE.
Fix SMFS to be consistent with this behaviour - move TX counter to the
last STE, this way the counter will include all actions of the previous STEs
that might have changed packet headers length, e.g. encap, vlan push, etc.

MDB is managed by extending mlx5 bridge to store an entry in
mlx5_esw_bridge->mdb_list linked list (used to iterate over all offloaded
MDBs) and mlx5_esw_bridge->mdb_ht hash table (used to lookup existing MDB
by MAC+VLAN). Every MDB entry can be attached to arbitrary amount of bridge
ports that are stored in mlx5_esw_bridge_mdb_entry->ports xarray in order
to allow both efficient lookup of the port and also iteration over all
ports that the entry is attached to. Every time MDB is attached/detached
to/from a port, the hardware rule is recreated with list of destinations
corresponding to all attached ports. When the entry is detached from the
last port it is removed from mdb and destroyed which means that the ports
xarray also acts as implicit reference counting mechanism.

- Flow group of size one that matches all packets and forwards them to the

Drivers call netdev_tx_completed_queue() right before
netif_txq_maybe_wake(). If BQL is enabled netdev_tx_completed_queue()
should issue a memory barrier, so we can depend on that separating
the stop check from the consumer index update, instead of adding
another barrier in netif_txq_maybe_wake().
This matters more than the barriers on the xmit path, because
the wake condition is almost always true. So we issue the
consumer side barrier often.
Wrap netdev_tx_completed_queue() in a local helper to issue
the barrier even if BQL is disabled. Keep the same semantics
as netdev_tx_completed_queue() (barrier only if bytes != 0)
to make it clear that the barrier is conditional.
Plus since macro gets pkt/byte counts as arguments now -
we can skip waking if there were no packets completed.

Convert bnxt to use new macros rather than open code the logic.
Two differences:
(1) bnxt_tx_int() will now only issue a memory barrier if it sees
enough space on the ring to wake the queue. This should be fine,
the mb() is between the writes to the ring pointers and checking
queue state.
(2) we'll start the queue instead of waking on race, this should
be safe inside the xmit handler.

A lot of drivers follow the same scheme to stop / start queues
without introducing locks between xmit and NAPI tx completions.
I'm guessing they all copy'n'paste each other's code.
The original code dates back all the way to e1000 and Linux 2.6.19.
Smaller drivers shy away from the scheme and introduce a lock
which may cause deadlocks in netpoll.
Provide macros which encapsulate the necessary logic.
The macros do not prevent false wake ups, the extra barrier
required to close that race is not worth it. See discussion in:

There was a sort of rush surrounding commit 88c0a6b503b7 ("net: create a
netdev notifier for DSA to reject PTP on DSA master"), due to a desire
to convert DSA's attempt to deny TX timestamping on a DSA master to
something that doesn't block the kernel-wide API conversion from
ndo_eth_ioctl() to ndo_hwtstamp_set().
What was required was a mechanism that did not depend on ndo_eth_ioctl(),
and what was provided was a mechanism that did not depend on
ndo_eth_ioctl(), while at the same time introducing something that
wasn't absolutely necessary - a new netdev notifier.
There have been objections from Jakub Kicinski that using notifiers in
general when they are not absolutely necessary creates complications to
the control flow and difficulties to maintainers who look at the code.
So there is a desire to not use notifiers.
In addition to that, the notifier chain gets called even if there is no
DSA in the system and no one is interested in applying any restriction.
Take the model of udp_tunnel_nic_ops and introduce a stub mechanism,
through which net/core/dev_ioctl.c can call into DSA even when
CONFIG_NET_DSA=m.
Compared to the code that existed prior to the notifier conversion, aka
what was added in commits:
- 4cfab3566710 ("net: dsa: Add wrappers for overloaded ndo_ops")
- 3369afba1e46 ("net: Call into DSA netdevice_ops wrappers")
this is different because we are not overloading any struct
net_device_ops of the DSA master anymore, but rather, we are exposing a
rather specific functionality which is orthogonal to which API is used
to enable it - ndo_eth_ioctl() or ndo_hwtstamp_set().
Also, what is similar is that both approaches use function pointers to
get from built-in code to DSA.
There is no point in replicating the function pointers towards
__dsa_master_hwtstamp_validate() once for every CPU port (dev->dsa_ptr).
Instead, it is sufficient to introduce a singleton struct dsa_stubs,
built into the kernel, which contains a single function pointer to
__dsa_master_hwtstamp_validate().
I find this approach preferable to what we had originally, because
dev->dsa_ptr->netdev_ops->ndo_do_ioctl() used to require going through
struct dsa_port (dev->dsa_ptr), and so, this was incompatible with any
attempts to add any data encapsulation and hide DSA data structures from
the outside world.

====================
Add support for J784S4 CPSW9G
This series adds a new compatible to am65-cpsw driver for the CPSW9G
instance of the CPSW Ethernet Switch on TI's J784S4 SoC which has 8
external ports and 1 internal host port.
The CPSW9G instance supports QSGMII and USXGMII modes for which driver
support is added.
Additionally, the interface mode specific configurations are moved to the
am65_cpsw_nuss_mac_config() callback. Also, a TODO comment is added for
verifying whether in-band mode is necessary for 10 Mbps RGMII mode.
NOTE:
I have verified that the mac_config() operations are preserved across
link up and link down events for SGMII and USXGMII mode with the new
implementation in this series, as suggested by:
Russell King <linux@armlinux.org.uk>
For patches 1 and 3 of this series, I believe that the following tag:
Suggested-by: Russell King <linux@armlinux.org.uk>
should be added. However, I did not add it since I did not yet get
the permission to do so. I will be happy if the tags are added, since
the new implementation is almost entirely based on Russell's suggestion,
with minor changes made by me.

TI's J784S4 SoC supports USXGMII mode. Add USXGMII mode to the
extra_modes member of the J784S4 SoC data.
Configure MAC control register for supporting USXGMII mode and add
MAC_5000FD in the "mac_capabilities" member of struct "phylink_config".

QSGMII support for it by adding QSGMII mode to the extra_modes member of
the "j784s4_cpswxg_pdata" SoC data.

Move the interface mode specific configuration to the mac_config()
callback am65_cpsw_nuss_mac_config().
Also, do not reset the MAC Control register on mac_link_down(). Only
clear those bits that can possibly be set in mac_link_up().
Let the MAC remain in IDLE state after mac_link_down(). Bring it out of
the IDLE state on mac_link_up().

HWmon core receives an array of pointers to hwmon_channel_info and it
does not modify it, thus it can be array of const pointers for safety.
This allows drivers to make them also const.

When a device is roaming between interfaces and a new flow entry is
created, we should assume that its output device is more up to date than
whatever entry existed already.

WED version 2 (on MT7986 and later) can offload flows originating from
wireless devices.
In order to make that work, ndo_setup_tc needs to be implemented on the
netdevs. This adds the required code to offload flows coming in from WED,
while keeping track of the incoming wed index used for selecting the
correct PPE device.
