Introduce and use per vport ACL tables creation and destroy APIs, so that
subsequently patch can use them during enabling/disabling a vport in
unified way for legacy vs offloads mode.

In subsequent patch, esw_enable_vport() could fail and return error.
Prepare code to handle such error.

When eswitch is disabled, vport event handler is unregistered.
This unregistration already synchronizes with running EQ event handler
in below code flow.
mlx5_eswitch_disable()
mlx5_eswitch_event_handlers_unregister()
mlx5_eq_notifier_unregister()
atomic_notifier_chain_unregister()
synchronize_rcu()
notifier_callchain
eswitch_vport_event()
queue_work()
Additionally vport->enabled flag is set under state_lock during
esw_enable_vport() but is not read under state_lock in
(a) esw_disable_vport() and (b) under atomic context
eswitch_vport_event().
It is also necessary to synchronize with already scheduled vport event.
This is already achieved using below sequence.
mlx5_eswitch_event_handlers_unregister()
[..]
flush_workqueue()
Hence,
(a) Remove vport->enabled check in eswitch_vport_event() which
doesn't make any sense.
(b) Remove redundant flush_workqueue() on every vport disable.
(c) Keep esw_disable_vport() symmetric with esw_enable_vport() for
state_lock.

Currently esw_enable_vport() does vport check for zero to enable drop
counters regardless of execution on ECPF/PF.
While esw_disable_vport() considers such scenario.
To keep consistency across code for checking for manager_vport,
introduce and use mlx5_esw_is_manager_vport() to check if a specified
vport is eswitch manager vport or not.

irqreturn_t type is an enum and in this context it's unsigned, so "err"
can't be irqreturn_t or it breaks the error handling. In fact the "err"
variable is only used to store integers (never irqreturn_t) so it should
be declared as int.
I removed the initialization because it's not required. Using a bogus
initializer turns off GCC's uninitialized variable warnings. Secondly,
there is a GCC warning about unused assignments and we would like to
enable that feature eventually so we have been trying to remove these
unnecessary initializers.

This patch converts the MACB Ethernet driver to the Phylink framework.
The MAC configuration is moved to the Phylink ops and Phylink helpers
are now used in the ethtools functions. This helps to access the flow
control and pauseparam logic and this will be helpful in the future for
boards using this controller with SFP cages.

To enable xilinx axi_emac driver support on zynqmp ultrascale platform
(ARCH64) there are two choices, mention ARCH64 as a dependency list
and other is to check if this ARCH dependency list is really needed.
Later approach seems more reasonable, so remove the obsolete ARCH
dependency list for the axi_emac driver.

The BCM2711 needs a different maximum DMA burst length. If not set
accordingly a timeout in the transmit queue happens and no package
can be sent. So use the new compatible to derive this value.
Until now the GENET HW version was used as the platform identifier.
This doesn't work with SoC-specific modifications, so introduce a proper
platform data structure.

The sfc driver can drop packets processed with XDP, notably when running
out of buffer space on XDP_TX, or returning an unknown XDP action.
This increments the rx_xdp_bad_drops ethtool counter.
Call trace_xdp_exception everywhere rx_xdp_bad_drops is incremented,
except for fragmented RX packets as the XDP program hasn't run yet.
This allows it to easily be monitored from userspace.
This mirrors the behavior of other drivers.

In case the firmware had an error while processing EMADs, it can send back
an ASCII string with the reason using EMAD string TLV.
This patch adds the support for using EMAD string TLV. In case of an error,
reports the reason using devlink hwerr tracepoint.

Until now the code assumes a fixed structure which makes it difficult to
support EMADs with and without new TLVs.
Make it more generic by parsing the TLVs when the EMADs are received and
store the offset to the different TLVs in the control block. Using these
offsets to extract information from the EMADs without relying on a specific
structure.

This looks over-engineered. Let's use some helpers to get the buffer
length and hereby simplify the stmmac_rx() function. No performance drop

Add support for chip version RTL8117. Settings have been copied from
Realtek's r8168 driver, there however chip ID 54a belongs to a chip
version called RTL8168FP. It was confirmed that RTL8117 works with
Realtek's driver, so both chip versions seem to be the same or at
least compatible.
