Adding flow director filters stopped working correctly after
commit 2fba7dc5157b ("ice: Add support for XDP multi-buffer
on Rx side"). As a result, only first flow director filter
can be added, adding next filter leads to NULL pointer
dereference attached below.
Rx buffer handling and reallocation logic has been optimized,
however flow director specific traffic was not accounted for.
As a result driver handled those packets incorrectly since new
logic was based on ice_rx_ring::first_desc which was not set
in this case.
Fix this by setting struct ice_rx_ring::first_desc to next_to_clean
for flow director received packets.

With clang's kernel control flow integrity (kCFI, CONFIG_CFI_CLANG),
indirect call targets are validated against the expected function
pointer prototype to make sure the call target is valid to help mitigate
ROP attacks. If they are not identical, there is a failure at run time,
which manifests as either a kernel panic or thread getting killed. A
warning in clang aims to catch these at compile time, which reveals:
drivers/net/ethernet/pasemi/pasemi_mac.c:1665:21: error: incompatible function pointer types initializing 'netdev_tx_t (*)(struct sk_buff *, struct net_device *)' (aka 'enum netdev_tx (*)(struct sk_buff *, struct net_device *)') with an expression of type 'int (struct sk_buff *, struct net_device *)' [-Werror,-Wincompatible-function-pointer-types-strict]
.ndo_start_xmit = pasemi_mac_start_tx,
^~~~~~~~~~~~~~~~~~~
1 error generated.
->ndo_start_xmit() in 'struct net_device_ops' expects a return type of
'netdev_tx_t', not 'int'. Adjust the return type of
pasemi_mac_start_tx() to match the prototype's to resolve the warning.
While PowerPC does not currently implement support for kCFI, it could in
the future, which means this warning becomes a fatal CFI failure at run
time.

The Geneve encapsulation, as defined in RFC 8926, has a Protocol Type
field, which states the Ethertype of the payload appearing after the
Geneve header.
Commit 435fe1c0c1f7 ("net: geneve: support IPv4/IPv6 as inner protocol")
introduced a new IFLA_GENEVE_INNER_PROTO_INHERIT flag that allowed the
use of other Ethertypes than Ethernet. However, it did not get rid of a
restriction that prohibits receiving payloads other than Ethernet,
instead the commit white-listed additional Ethertypes, IPv4 and IPv6.
This patch removes this restriction, making it possible to receive any
Ethertype as a payload, if the IFLA_GENEVE_INNER_PROTO_INHERIT flag is
set.
The restriction was set in place back in commit 0b5e8b8eeae4
("net: Add Geneve tunneling protocol driver"), which implemented a
protocol layer driver for Geneve to be used with Open vSwitch. The
relevant discussion about introducing the Ethertype white-list can be
found here:
https://lore.kernel.org/netdev/CAEP_g=_1q3ACX5NTHxLDnysL+dTMUVzdLpgw1apLKEdDSWPztw@mail.gmail.com/
<quote>
>> + if (unlikely(geneveh->proto_type != htons(ETH_P_TEB)))

> Why? I thought the point of geneve carrying protocol field was to
> allow protocols other than Ethernet... is this temporary maybe?
Yes, it is temporary. Currently OVS only handles Ethernet packets but
this restriction can be lifted once we have a consumer that is capable
of handling other protocols.
</quote>
This white-list was then ported to a generic Geneve netdevice in commit
371bd1061d29 ("geneve: Consolidate Geneve functionality in single
module."). Preserving the Ethertype white-list at this point made sense,
as the Geneve device could send out only Ethernet payloads anyways.
However, now that the Geneve netdevice supports encapsulating other
payloads with IFLA_GENEVE_INNER_PROTO_INHERIT and we have a consumer
capable of other protocols, it seems appropriate to lift the restriction
and allow any Geneve payload to be received.

CoreSight ETM4x architecture clearly provides ways to identify a device
via registers in the "Management" class, TRCDEVARCH and TRCDEVTYPE. These
registers can be accessed without the Trace domain being powered on.
We additionally added TRCIDR1 as fallback in order to cover for any
ETMs that may not have implemented TRCDEVARCH. So far, nobody has
reported hitting a WARNING we placed to catch such systems.
Also, more importantly it is problematic to access TRCIDR1, which is a
"Trace" register via MMIO access, without clearing the OSLK. But we cannot
mess with the OSLK until we know for sure that this is an ETMv4 device.
Thus, this kind of creates a chicken and egg problem unnecessarily for
systems "which are compliant" to the ETMv4 architecture.
Let us remove the TRCIDR1 fall back check and rely only on TRCDEVARCH.

Like the Windows Lenovo Yoga Book X91F/L the Android Lenovo Yoga Book

add a quirk for this.
When the quirk for the X91F/L was initially added it was written to
also apply to the X90F/L but this does not work because the Android
version of the Yoga Book uses completely different DMI strings.
Also adjust the X91F/L quirk to reflect that it only applies to

The SGMII core found in several MediaTek SoCs is identical to what can
also be found in MediaTek's MT7531 Ethernet switch IC.
As this has not always been clear, both drivers developed different
implementations to deal with the PCS.
Recently Alexander Couzens pointed out this fact which lead to the
development of this shared driver.
Add a dedicated driver, mostly by copying the code now found in the
Ethernet driver. The now redundant code will be removed by a follow-up
commit.

The previous commit 6a192c0cbf38 ("platform/x86/intel/tpmi: Fix
double free reported by Smatch") incorrectly handle the deallocation of
res variable. As shown in the comment, intel_vsec_add_aux handles all
the deallocation of res and feature_vsec_dev. Therefore, kfree(res) can
still cause double free if intel_vsec_add_aux returns error.
Fix this by adjusting the error handling part in tpmi_create_device,
following the function intel_vsec_add_dev.

The Amlogic Meson internal PHY's have the same register layout as
certain SMSC PHY's (also for non-c22-standard registers). This seems
to be more than just coincidence. Apparently they also need the same
workaround for EDPD mode (energy detect power down). Therefore let's
reuse SMSC PHY driver functionality in the meson-gxl PHY driver.
Tested with a G12A internal PHY. I don't have GXL test hw,
therefore I replace only the callbacks that are identical in
the SMSC PHY driver.

enough to allow for this alignment.
Also, correct the maximum and minimum MTU sizes, and add a new
preprocessor macro for the maximum frame size, GELIC_NET_MAX_FRAME.

Currently one counter is shared between all IPsec Tx offloaded
rules to count the total amount of packets/bytes that was IPsec
Tx offloaded, replace this scheme by adding a new flow table (ft)
with one rule that counts all flows that passes through this
table (like Rx status ft), this ft is pointed by all IPsec Tx
offloaded rules. The above allows to have a counter per tx flow
rule in while keeping a separate global counter that store the
aggregation outcome of all these per flow counters.

During XFRM stack acquire flow, a default SA is created to be updated
later, once acquire netlink message is handled in user space.
This SA is also passed to IPsec offload supporting driver, however this
SA acts only as placeholder and does not have context suitable for
offloading in HW yet. Identify this kind of SA by special offload flag
(XFRM_DEV_OFFLOAD_FLAG_ACQ), and create a SW only context.
In such cases with special mark so it won't be installed in HW in addition
