Currently, device V1 and V2 do not support segmentation
offload for UDP based tunnel packet who needs outer UDP
checksum offload, so there is a workaround in the driver
to set the checksum of the outer UDP checksum as zero. This
is not what the user wants, so remove this feature for
device V1 and V2, add support for it later(when the device
has the ability to do that).

For the device that supports TX hardware checksum, the hardware
can calculate the checksum from the start and fill the checksum
to the offset position, which reduces the operations of
calculating the type and header length of L3/L4. So add this
feature for the HNS3 ethernet driver.
The previous simple BD description is unsuitable, rename it as
HW TX CSUM.

For XDP TX, even tough we start out with correctly aligned buffers, the
XDP program might change the data's alignment. For REDIRECT, we have no
control over the alignment either.
Create a new workaround for xdp_frame structures to verify the erratum
conditions and move the data to a fresh buffer if necessary. Create a new
xdp_frame for managing the new buffer and free the old one using the XDP
API.
Due to alignment constraints, all frames have a 256 byte headroom that
is offered fully to XDP under the erratum. If the XDP program uses all
of it, the data needs to be move to make room for the xdpf backpointer.
Disable the metadata support since the information can be lost.

Use an xdp_frame structure for managing the frame. Store a backpointer to
the structure at the start of the buffer before enqueueing for cleanup
on TX confirmation. Reserve DPAA_TX_PRIV_DATA_SIZE bytes from the frame
size shared with the XDP program for this purpose. Use the XDP
API for freeing the buffer when it returns to the driver on the TX
confirmation path.
The frame queues are shared with the netstack. The DPAA driver is a LLTX
driver so no explicit locking is required on transmission.
This approach will be reused for XDP REDIRECT.

Implement the XDP_DROP and XDP_PASS actions.
Avoid draining and reconfiguring the buffer pool at each XDP
setup/teardown by increasing the frame headroom and reserving
XDP_PACKET_HEADROOM bytes from the start. Since we always reserve an
entire page per buffer, this change only impacts Jumbo frame scenarios
where the maximum linear frame size is reduced by 256 bytes. Multi
buffer Scatter/Gather frames are now used instead in these scenarios.
Allow XDP programs to access the entire buffer.
The data in the received frame's headroom can be overwritten by the XDP
program. Extract the relevant fields from the headroom while they are
still available, before running the XDP program.
Since the headroom might be resized before the frame is passed up to the
stack, remove the check for a fixed headroom value when building an skb.
Allow the meta data to be updated and pass the information up the stack.
Scatter/Gather frames are dropped when XDP is enabled.

The offsets for almost all GSI registers we use have different
offsets starting at IPA version 4.5. Only two registers remain
in their original location.
In a way though, the new register locations are not *that*
different. The entire group of affected registers has simply
been shifted down in memory by a fixed amount (0xd000). So for
example, the channel context 0 register that has a base offset of
0x0001c000 for "older" hardware now has a base offset of 0x0000f000.
This patch aims to add support for IPA v4.5 registers at their new
offets in a way that minimizes the amount of code that needs to
change. It is not ideal, but it avoids the need to maintain
a nearly complete set of additional register offset definitions.
The approach takes advantage of the fact that when accessing GSI
registers we do not access any of memory at lower end of the "gsi"
memory range (with two exceptions already noted). In particular,
we do not access anything within the bottom 0xd000 bytes of the
GSI memory range.
For IPA version 4.5, after we map the GSI memory, we adjust the
virtual memory pointer downward by the fixed amount (0xd000).
That way, register accesses using the offsets defined by the
existing GSI_REG_*() macros will resolve to the proper locations
for IPA version 4.5.
The two registers *not* affected by this offset are accessed only
in gsi_irq_setup(). There, for IPA version 4.5, we undo the general
register adjustment by adding the fixed amount back to the virtual
address to access these registers.

Update the IPA code to make use of the updated IPA v4.5 register
definitions. Generally what this patch does is, if IPA v4.5
hardware is in use:
- Ensure new registers or fields in IPA v4.5 are updated where
required
- Ensure registers or fields not supported in IPA v4.5 are not
examined when read, or are set to 0 when written
It does this while preserving the existing functionality for IPA
versions lower than v4.5.
The values to program for QSB_MAX_READS and QSB_MAX_WRITES and the
source and destination resource counts are updated to be correct for
all versions through v4.5 as well.
Note that IPA_RESOURCE_GROUP_SRC_MAX and IPA_RESOURCE_GROUP_DST_MAX
already reflect that 5 is an acceptable number of resources (which
IPA v4.5 implements).

IPA v4.5 adds a few fields to the endpoint header and extended
header configuration registers that represent new high-order bits
for certain offsets and sizes. Add code to incorporate these upper
bits into the registers for IPA v4.5.
This includes creating ipa_header_size_encoded(), which handles
encoding the metadata offset field for use in the ENDP_INIT_HDR
register in a way appropriate for the hardware version. This and
ipa_metadata_offset_encoded() ensure the mask argument passed to
u32_encode_bits() is constant.

Update "ipa_reg.h" so that register definitions support IPA hardware
version 4.5, in addition to versions 3.5.1 through v4.2. Most of
the register definitions are the same, but in some cases fields are
added, changed, or eliminated.
Updates for a few IPA v4.5 registers are more complex, and adding
those definition will be deferred to separate patches. This patch
only updates the register offset and field definitions, and adds
informational comments.
The only code change avoids accessing the backward compatibility
register for IPA version 4.5 in ipa_hardware_config(). Other IPA
v4.5-specific code changes will come later.

The device supports an operation that allows the driver to issue one
request to update the adjacency index for all the routes in a given
virtual router (VR) from old index and size to new ones. This is useful
in case the configuration of a certain nexthop group is updated and its
adjacency index changes.
Currently, the driver does not use this operation in an efficient
manner. It iterates over all the routes using the nexthop group and
issues an update request for the VR if it is not the same as the
previous VR.
Instead, use the VR tracking added in the previous patch to update the
adjacency index once for each VR currently using the nexthop group.
Example:
8k IPv6 routes were added in an alternating manner to two VRFs. All the
routes are using the same nexthop object ('nhid 1').
Before:
# perf stat -e devlink:devlink_hwmsg --filter='incoming==0' -- ip nexthop replace id 1 via 2001:db8:1::2 dev swp3
Performance counter stats for 'ip nexthop replace id 1 via 2001:db8:1::2 dev swp3':

Number of EMAD transactions corresponds to number of routes using the
nexthop group.
After:
# perf stat -e devlink:devlink_hwmsg --filter='incoming==0' -- ip nexthop replace id 1 via 2001:db8:1::2 dev swp3

Pull mtd fixes from Miquel Raynal:
"Because of a recent change in the core, NAND controller drivers
initializing the ECC engine too early in the probe path are broken.
Drivers should wait for the NAND device to be discovered and its
memory layout known before doing any ECC related initialization, so
instead of reverting the faulty change which is actually moving in the
right direction, let's fix the drivers directly: socrates, sharpsl,
r852, plat_nand, pasemi, tmio, txx9ndfmc, orion, mpc5121, lpc32xx_slc,
lpc32xx_mlc, fsmc, diskonchip, davinci, cs553x, au1550, ams-delta,

Pull drm fixes from Dave Airlie:
"Unfortunately this has a bit of thanksgiving stuffing in it, as it a
bit larger (at least the vc4 patches) than I like at this point in
time.
The main thing is it has a bunch of regressions fixes for reports in
the last couple of weeks, ast, nouveau and the amdgpu ttm init fix,
along with the usual selection of amdgpu and i915 fixes.
The vc4 fixes are a few but they are fixes and the nastiest one is a
fix for when you have a 2.4Ghz Wifi and a HDMI signal with a clock in
that range and there isn't enough shielding and interference happen
between the two, the fix adjusts the mode clock to try and avoid the
wifi channels in that case.
Hopefully you can merge this between turkey slices, and next week
should be quieter.
ast:
- LUT loading regression fix
nouveau:
- relocations regression fix
amdgpu:
- ttm init oops fix
- Runtime pm fix
- SI UVD suspend/resume fix
- HDCP fix for headless cards
- Sienna Cichlid golden register update
i915:
- Fix Perf/OA workaround register corruption (Lionel)
- Correct a comment statement in GVT (Yan)
- Fix GT enable/disable iterrupts, including a race condition that
prevented GPU to go idle (Chris)
- Free stale request on destroying the virtual engine (Chris)
exynos:
- config dependency fix
mediatek:
- unused var removal
- horizonal front/back porch formula fix
vc4:
- wifi and hdmi interference fix
- mode rejection fixes
- use after free fix
- cleanup some code"

git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
Pull arm64 fixes from Will Deacon:
"The main changes are relating to our handling of access/dirty bits,
where our low-level page-table helpers could lead to stale young
mappings and loss of the dirty bit in some cases (the latter has not
been observed in practice, but could happen when clearing "soft-dirty"
if we enabled that). These were posted as part of a larger series, but
the rest of that is less urgent and needs a v2 which I'll get to
shortly.
In other news, we've now got a set of fixes to resolve the
lockdep/tracing problems that have been plaguing us for a while, but
they're still a bit "fresh" and I plan to send them to you next week
after we've got some more confidence in them (although initial CI
results look good).
Summary:
- Fix kerneldoc warnings generated by ACPI IORT code
- Fix pte_accessible() so that access flag is ignored
- Fix missing header #include
- Fix loss of software dirty bit across pte_wrprotect() when HW DBM
is enabled"
