The value passed as the l3_proto argument of mvneta_txq_desc_csum()
is __be16. And mvneta_txq_desc_csum uses this parameter as a __be16
value. So use __be16 as the type for the parameter, rather than
type with host byte order.
Flagged by Sparse as:
.../mvneta.c:1796:25: warning: restricted __be16 degrades to integer
.../mvneta.c:1979:45: warning: incorrect type in argument 2 (different base types)
.../mvneta.c:1979:45: expected int l3_proto
.../mvneta.c:1979:45: got restricted __be16 [usertype] l3_proto
No functional change intended.

'struct config_item_type' is not modified in this driver.
This structure is only used with config_group_init_type_name() which takes
a const struct config_item_type* as a 3rd argument.
This also makes things consistent with 'netconsole_target_type' witch is
already const.
Constifying this structure moves some data to a read-only section, so
increase overall security, especially when the structure holds some
function pointers.
On a x86_64, with allmodconfig:

Add support for offloading cls U32 filters. Only "skbedit queue_mapping"
and "drop" actions are supported. Also, only "ip" and "802_3" tc
protocols are allowed. The PF must advertise the VIRTCHNL_VF_OFFLOAD_TC_U32
capability flag.
Since the filters will be enabled via the FD stage at the PF, a new type
of FDIR filters is added and the existing list and state machine are used.
The new filters can be used to configure flow directors based on raw
(binary) pattern in the rx packet.
Examples:
0. # tc qdisc add dev enp175s0v0 ingress
1. Redirect UDP from src IP 192.168.2.1 to queue 12:
# tc filter add dev <dev> protocol ip ingress u32 \
match u32 0x45000000 0xff000000 at 0 \
match u32 0x00110000 0x00ff0000 at 8 \
match u32 0xC0A80201 0xffffffff at 12 \
match u32 0x00000000 0x00000000 at 24 \
action skbedit queue_mapping 12 skip_sw
2. Drop all ICMP:
# tc filter add dev <dev> protocol ip ingress u32 \
match u32 0x45000000 0xff000000 at 0 \
match u32 0x00010000 0x00ff0000 at 8 \
match u32 0x00000000 0x00000000 at 24 \
action drop skip_sw
3. Redirect ICMP traffic from MAC 3c:fd:fe:a5:47:e0 to queue 7
(note proto: 802_3):
# tc filter add dev <dev> protocol 802_3 ingress u32 \
match u32 0x00003CFD 0x0000ffff at 4 \
match u32 0xFEA547E0 0xffffffff at 8 \
match u32 0x08004500 0xffffff00 at 12 \
match u32 0x00000001 0x000000ff at 20 \
match u32 0x0000 0x0000 at 40 \
action skbedit queue_mapping 7 skip_sw
Notes on matches:
1 - All intermediate fields that are needed to parse the correct PTYPE
must be provided (in e.g. 3: Ethernet Type 0x0800 in MAC, IP version
and IP length: 0x45 and protocol: 0x01 (ICMP)).
2 - The last match must provide an offset that guarantees all required
headers are accounted for, even if the last header is not matched.
For example, in #2, the last match is 4 bytes at offset 24 starting
from IP header, so the total is 14 (MAC) + 24 + 4 = 42, which is the
sum of MAC+IP+ICMP headers.

In preparation for a second type of FDIR filters that can be added by
tc-u32, move the add/del of the FDIR logic to be entirely contained in
iavf_fdir.c.
The iavf_find_fdir_fltr_by_loc() is renamed to iavf_find_fdir_fltr()
to be more agnostic to the filter ID parameter (for now @loc, which is
relevant only to current FDIR filters added via ethtool).
The FDIR filter deletion is moved from iavf_del_fdir_ethtool() in
ethtool.c to iavf_fdir_del_fltr(). While at it, fix a minor bug where
the "fltr" is accessed out of the fdir_fltr_lock spinlock protection.

[why & how]
When the commit 9d84c7ef8a87 ("drm/amd/display: Correct cursor position
on horizontal mirror") was introduced, it used the wrong calculation for
the position copy for X. This commit uses the correct calculation for that
based on the original patch.

[why & how]
Cursor gets clipped off in the middle of the screen with hw
rotation 180. Fix a miscalculation of cursor offset when it's
placed near the edges in the pipe split case.
Cursor bugs with hw rotation were reported on AMD issue
tracker:
https://gitlab.freedesktop.org/drm/amd/-/issues/2247
The issues on rotation 270 was fixed by:
https://lore.kernel.org/amd-gfx/20221118125935.4013669-22-Brian.Chang@amd.com/
that partially addressed the rotation 180 too. So, this patch is the
final bits for rotation 180.

A recent change to the driver exposed a bug where the MAC RX
filters (unicast MAC, broadcast MAC, and multicast MAC) are
configured and enabled before the RX path is fully initialized.
The result of this bug is that after the PHY is started packets
that match these MAC RX filters start to flow into the RX FIFO.
And then, after rx_init() is completed, these packets will go
into the driver RX ring as well. If enough packets are received
to fill the RX ring (default size is 128 packets) before the call
to request_irq() completes, the driver RX function becomes stuck.
This bug is intermittent but is most likely to be seen where the
oob_net0 interface is connected to a busy network with lots of
broadcast and multicast traffic.
All the MAC RX filters must be disabled until the RX path is ready,
i.e. all initialization is done and all the IRQs are installed.

If the dm_resume method is called on a device that is not suspended, the
method will suspend the device briefly, before resuming it (so that the
table will be swapped).
However, there was a bug that the return value of dm_suspended_md was not
checked. dm_suspended_md may return an error when it is interrupted by a
signal. In this case, do_resume would call dm_swap_table, which would
return -EINVAL.
This commit fixes the logic, so that error returned by dm_suspend is
checked and the resume operation is undone.

Commit 60fa6ae6e6d0 ("ACPI: EC: Install address space handler at the
namespace root") caused _REG methods for EC operation regions outside
the EC device scope to be evaluated which on some systems leads to the
evaluation of _REG methods in the scopes of device objects representing
devices that are not present and not functional according to the _STA
return values. Some of those device objects represent EC "alternatives"
and if _REG is evaluated for their operation regions, the platform
firmware may be confused and the platform may start to behave
incorrectly.
To avoid this problem, only evaluate _REG for EC operation regions
located in the scopes of device objects representing known-to-be-present
devices.
For this purpose, partially revert commit 60fa6ae6e6d0 and trigger the
evaluation of _REG for EC operation regions from acpi_bus_attach() for
the known-valid devices.

doorbell rings
After napi_complete_done() is called when NAPI is polling in the current
process context, another NAPI may be scheduled and start running in
softirq on another CPU and may ring the doorbell before the current CPU
does. When combined with unnecessary rings when there is no need to arm
the CQ, it triggers error paths in the hardware.
This patch fixes this by calling napi_complete_done() after doorbell
rings. It limits the number of unnecessary rings when there is
no need to arm. MANA hardware specifies that there must be one doorbell
ring every 8 CQ wraparounds. This driver guarantees one doorbell ring as
soon as the number of consumed CQEs exceeds 4 CQ wraparounds. In practical
workloads, the 4 CQ wraparounds proves to be big enough that it rarely
exceeds this limit before all the napi weight is consumed.
To implement this, add a per-CQ counter cq->work_done_since_doorbell,
and make sure the CQ is armed as soon as passing 4 wraparounds of the CQ.
