BCM4908 uses 2 Gbps link between switch and the Ethernet interface.
Without this BCM4908 devices were able to achieve only 2 x ~895 Mb/s.
This allows handling e.g. NAT traffic with 940 Mb/s.

pxa168_eth_remove() firstly calls unregister_netdev(),
then cancels a timeout work. unregister_netdev() shuts down a device
interface and removes it from the kernel tables. If the timeout occurs
in parallel, the timeout work (pxa168_eth_tx_timeout_task) performs stop
and open of the device. It may lead to an inconsistent state and memory
leaks.

Now that the dpaa2-switch driver has basic I/O capabilities on the
switch port net_devices and multiple bridging domains are supported,
move the driver out of staging.
The dpaa2-switch driver is placed right next to the dpaa2-eth driver
since, in the near future, they will be sharing most of the data path.
I didn't implement code reuse in this patch series because I wanted to
keep it as small as possible.
Also, the README is removed from staging with the intention to add
proper rst documentation afterwards to actually match was is supported
by the driver.

Since commit fd5736bf9f23 ("enetc: Workaround for MDIO register access
issue"), enetc_refill_rx_ring no longer updates the RX BD ring's
consumer index, that is left to be done by the caller. This has led to
bugs such as the ones found in 96a5223b918c ("net: enetc: remove bogus
write to SIRXIDR from enetc_setup_rxbdr") and 3a5d12c9be6f ("net: enetc:
keep RX ring consumer index in sync with hardware"), so it is desirable
that we move back the update of the consumer index into enetc_refill_rx_ring.
The trouble with that is the different MDIO locking context for the two
callers of enetc_refill_rx_ring:
- enetc_clean_rx_ring runs under enetc_lock_mdio()
- enetc_setup_rxbdr runs outside enetc_lock_mdio()
Simplify the callers of enetc_refill_rx_ring by making enetc_setup_rxbdr
explicitly take enetc_lock_mdio() around the call. It will be the only
place in need of ensuring the hot accessors can be used.

When we iterate through the BDs in the RX ring, the software producer
index (which is already passed by value to enetc_rxbd_next) lags behind,
and we end up with this funny looking "++i == rx_ring->bd_count" check
so that we drag it after us.
Let's pass the software producer index "i" by reference, so that
enetc_rxbd_next can increment it by itself (mod rx_ring->bd_count),
especially since enetc_rxbd_next has to increment the index anyway.

Since commit 3222b5b613db ("net: enetc: initialize RFS/RSS memories for
unused ports too") there is a requirement to initialize the memories of
unused PFs too, which has left the probe path in a bit of a rough shape,
because we basically have a minimal initialization path for unused PFs
which is separate from the main initialization path.
Now that initializing a control BD ring is as simple as calling
enetc_setup_cbdr, let's move that outside of enetc_alloc_si_resources
(unused PFs don't need classification rules, so no point in allocating
them just to free them later).
But enetc_alloc_si_resources is called both for PFs and for VFs, so now
that enetc_setup_cbdr is no longer called from this common function, it
means that the VF probe path needs to explicitly call enetc_setup_cbdr
too.

It makes no sense from an API perspective to first initialize some

enetc_clear_cbdr depends on struct enetc_hw because it must disable the

We shouldn't need to pass the struct device *dev to enetc CBDR APIs over
and over again, so save this inside struct enetc_cbdr::dma_dev and avoid
calling it from the enetc_free_cbdr functions.
This breaks the dependency of the cbdr API from struct enetc_si (the
station interface).

Recent versions of the PCI Express specification have deprecated support
for I/O transactions and actually some PCIe host bridges, such as Power
Systems Host Bridge 4 (PHB4), do not implement them. Conversely a DEFEA
adapter can have its MMIO decoding disabled with ECU (EISA Configuration
Utility) and therefore not available for us with the resource allocation
infrastructure we implement.
However either I/O address space will always be available for use with
the DEFEA (EISA) and DEFPA (PCI) adapters and both have double address
decoding implemented in hardware for Control and Status Register access.
The two kinds of adapters can be present both at once in a single mixed
PCI/EISA system. For the DEFTA (TURBOchannel) variant there is no issue
as there has been no port I/O address space defined for that bus.
To make people's life easier and the driver more robust remove the
DEFXX_MMIO configuration option so as to rather than making the choice
for the I/O address space to use at build time for all the adapters
installed in the system let the driver choose the most suitable address
space dynamically on a case-by-case basis at run time. Make MMIO the
default and resort to port I/O should the default fail for some reason.
This way multiple adapters installed in one system can use different I/O
address spaces each, in particular in the presence of DEFEA adapters in
a pure-EISA or a mixed EISA/PCI system (it is expected that DEFPA boards
will use MMIO in normal circumstances).
The choice of the I/O address space to use continues being reported by
the driver on startup, e.g.:
eisa 00:05: EISA: slot 5: DEC3002 detected
defxx: v1.12 2021/03/10 Lawrence V. Stefani and others
00:05: DEFEA at I/O addr = 0x5000, IRQ = 10, Hardware addr = 00-00-f8-c8-b3-b6
00:05: registered as fddi0
and:
defxx: v1.12 2021/03/10 Lawrence V. Stefani and others
0031:02:04.0: DEFPA at MMIO addr = 0x620c080020000, IRQ = 57, Hardware addr = 00-60-6d-93-91-98
0031:02:04.0: registered as fddi0
and:
defxx: v1.12 2021/03/10 Lawrence V. Stefani and others
tc2: DEFTA at MMIO addr = 0x1f100000, IRQ = 21, Hardware addr = 08-00-2b-b0-8b-1e
tc2: registered as fddi0
so there is no need to add further information.
The change is supposed to cause a negligible performance hit as I/O
accessors will now have code executed conditionally at run time.

Recent versions of the PCI Express specification have deprecated support
for I/O transactions and actually some PCIe host bridges, such as Power
Systems Host Bridge 4 (PHB4), do not implement them.
The default kernel configuration choice for the defxx driver is the use
of I/O ports rather than MMIO for PCI and EISA systems. It may have
made sense as a conservative backwards compatible choice back when MMIO
operation support was added to the driver as a part of TURBOchannel bus
support. However nowadays this configuration choice makes the driver
unusable with systems that do not implement I/O transactions for PCIe.
Make DEFXX_MMIO the configuration default then, except where configured
for EISA. This exception is because an EISA adapter can have its MMIO
decoding disabled with ECU (EISA Configuration Utility) and therefore
not available with the resource allocation infrastructure we implement,
while port I/O is always readily available as it uses slot-specific
addressing, directly mapped to the slot an option card has been placed
in and handled with our EISA bus support core. Conversely a kernel that
supports modern systems which may not have I/O transactions implemented
for PCIe will usually not be expected to handle legacy EISA systems.
The change of the default will make it easier for people, including but
not limited to distribution packagers, to make a working choice for the
driver.
Update the option description accordingly and while at it replace the
potentially ambiguous PIO acronym with IOP for "port I/O" vs "I/O ports"
according to our nomenclature used elsewhere.

Recent versions of the PCI Express specification have deprecated support
for I/O transactions and actually some PCIe host bridges, such as Power
Systems Host Bridge 4 (PHB4), do not implement them.
For those systems the PCI BARs that request a mapping in the I/O space
have the length recorded in the corresponding PCI resource set to zero,
which makes it unassigned:
# lspci -s 0031:02:04.0 -v
0031:02:04.0 FDDI network controller: Digital Equipment Corporation PCI-to-PDQ Interface Chip [PFI] FDDI (DEFPA) (rev 02)

I/O ports at <unassigned> [disabled]

Capabilities: [50] Power Management version 2
Kernel driver in use: defxx
Kernel modules: defxx
#
Regardless the driver goes ahead and requests it (here observed with a
Raptor Talos II POWER9 system), resulting in an odd /proc/ioport entry:
# cat /proc/ioports
00000000-ffffffffffffffff : 0031:02:04.0
#
Furthermore, the system gets confused as the driver actually continues
and pokes at those locations, causing a flood of messages being output
to the system console by the underlying system firmware, like:
defxx: v1.11 2014/07/01 Lawrence V. Stefani and others
defxx 0031:02:04.0: enabling device (0140 -> 0142)
LPC[000]: Got SYNC no-response error. Error address reg: 0xd0010000
IPMI: dropping non severe PEL event
LPC[000]: Got SYNC no-response error. Error address reg: 0xd0010014
IPMI: dropping non severe PEL event
LPC[000]: Got SYNC no-response error. Error address reg: 0xd0010014
IPMI: dropping non severe PEL event
and so on and so on (possibly intermixed actually, as there's no locking
between the kernel and the firmware in console port access with this
particular system, but cleaned up above for clarity), and once some 10k
of such pairs of the latter two messages have been produced an interace
eventually shows up in a useless state:
0031:02:04.0: DEFPA at I/O addr = 0x0, IRQ = 57, Hardware addr = 00-00-00-00-00-00
This was not expected to happen as resource handling was added to the
driver a while ago, because it was not known at that time that a PCI
system would be possible that cannot assign port I/O resources, and
oddly enough `request_region' does not fail, which would have caught it.
Correct the problem then by checking for the length of zero for the CSR
resource and bail out gracefully refusing to register an interface if
that turns out to be the case, producing messages like:
defxx: v1.11 2014/07/01 Lawrence V. Stefani and others
0031:02:04.0: Cannot use I/O, no address set, aborting
0031:02:04.0: Recompile driver with "CONFIG_DEFXX_MMIO=y"
Keep the original check for the EISA MMIO resource as implemented,
because in that case the length is hardwired to 0x400 as a consequence
of how the compare/mask address decoding works in the ESIC chip and it
is only the base address that is set to zero if MMIO has been disabled
for the adapter in EISA configuration, which in turn could be a valid
bus address in a legacy-free system implementing PCI, especially for
port I/O.
Where the EISA MMIO resource has been disabled for the adapter in EISA
configuration this arrangement keeps producing messages like:
eisa 00:05: EISA: slot 5: DEC3002 detected
defxx: v1.11 2014/07/01 Lawrence V. Stefani and others
00:05: Cannot use MMIO, no address set, aborting
00:05: Recompile driver with "CONFIG_DEFXX_MMIO=n"
00:05: Or run ECU and set adapter's MMIO location
with the last two lines now swapped for easier handling in the driver.
There is no need to check for and catch the case of a port I/O resource
not having been assigned for EISA as the adapter uses the slot-specific
I/O space, which gets assigned by how EISA has been specified and maps
directly to the particular slot an option card has been placed in. And
the EISA variant of the adapter has additional registers that are only
accessible via the port I/O space anyway.
While at it factor out the error message calls into helpers and fix an
argument order bug with the `pr_err' call now in `dfx_register_res_err'.

As explained in commit 29d98f54a4fe ("net: enetc: allow hardware
timestamping on TX queues with tc-etf enabled"), hardware TX
timestamping requires an skb with skb->tstamp = 0. When a packet is sent
with SO_TXTIME, the skb->skb_mstamp_ns corrupts the value of skb->tstamp,
so the drivers need to explicitly reset skb->tstamp to zero after
consuming the TX time.
Create a helper named skb_txtime_consumed() which does just that. All
drivers which offload TC_SETUP_QDISC_ETF should implement it, and it
would make it easier to assess during review whether they do the right
thing in order to be compatible with hardware timestamping or not.

There is a regular need in the kernel to provide a way to declare having
a dynamically sized set of trailing elements in a structure. Kernel code
should always use “flexible array members”[1] for these cases. The older
style of one-element or zero-length arrays should no longer be used[2].
Refactor the code according to the use of flexible-array members in
smt_sif_operation structure, instead of one-element arrays. Also, make
use of the struct_size() helper instead of the open-coded version
to calculate the size of the struct-with-flex-array. Additionally, make
use of the typeof operator to properly determine the object type to be
passed to macro smtod().
Also, this helps the ongoing efforts to enable -Warray-bounds by fixing
the following warnings:

The number of queues implemented by many virtio backends is limited,
especially some machines have a large number of CPUs. In this case, it
is often impossible to allocate a separate queue for
XDP_TX/XDP_REDIRECT, then xdp cannot be loaded to work, even xdp does
not use the XDP_TX/XDP_REDIRECT.
This patch allows XDP_TX/XDP_REDIRECT to run by reuse the existing SQ
with __netif_tx_lock() hold when there are not enough queues.

VF tunnel TX traffic offload is adding flow which forward to flow
tables with lower level, which isn't support on all FW versions
and may cause firmware to fail with syndrome.
Fixed by enabling VF tunnel TX offload only if flow table capability

flow_attr->ip_version has the matching that should be done inner/outer.
When working with chains, decapsulation is done on chain0 and next chain
match on outer header which is the original inner which could be ipv4.
So in tunnel route resolution we cannot use that to know which ip version
we are at so save tun_ip_version when parsing the tunnel match and use
that.
