Firmware doesn't allow flow rules in FDB to do header rewrite and send
packets to both internal and uplink vports. The following syndrome
will be generated when trying to offload such kind of rules:
mlx5_core 0000:08:00.0: mlx5_cmd_out_err:803:(pid 23569): SET_FLOW_TABLE_ENTRY(0x936) op_mod(0x0) failed, status bad parameter(0x3), syndrome (0x8c8f08), err(-22)
To avoid this syndrome, add a checking before creating FTE. If a rule
with header rewrite action forwards packets to both VF and PF, an
error is returned directly.

Even if the PF driver had no error on his part of the sync reset flow,
the firmware can see wider picture as it syncs all the PFs in the flow.

A new check for the tx devlink health reporter is introduced for
determining when the PTP port timestamping SQ is considered unhealthy. If
there are enough CQEs considered never to be delivered, the space that can
be utilized on the SQ decreases significantly, impacting performance and
usability of the SQ. The health reporter is triggered when the number of
likely never delivered port timestamping CQEs that utilize the space of the
PTP SQ is greater than 93.75% of the total capacity of the SQ. A devlink
health reporter recover method is also provided for this specific TX error
context that restarts the PTP SQ.

Use a map structure for associating CQEs containing port timestamping
information with the appropriate skb. Track order of WQEs submitted using a
FIFO. Check if the corresponding port timestamping CQEs from the lookup
values in the FIFO are considered dropped due to time elapsed. Return the
lookup value to a freelist after consuming the skb. Reuse the freed lookup
in future WQE submission iterations.
The map structure uses an integer identifier for the key and returns an skb
corresponding to that identifier. Embed the integer identifier in the WQE
submitted to the WQ for the transmit path when the SQ is a PTP (port
timestamping) SQ. The embedded identifier can then be queried using a field
in the CQE of the corresponding port timestamping CQ. In the port
timestamping napi_poll context, the identifier is queried from the CQE
polled from CQ and used to lookup the corresponding skb from the WQE submit
path. The skb reference is removed from map and then embedded with the port
HW timestamp information from the CQE and eventually consumed.
The metadata freelist FIFO is an array containing integer identifiers that
can be pushed and popped in the FIFO. The purpose of this structure is
bookkeeping what identifier values can safely be used in a subsequent WQE
submission and should not contain identifiers that have still not been
reaped by processing a corresponding CQE completion on the port
timestamping CQ.
The ts_cqe_pending_list structure is a combination of an array and linked
list. The array is pre-populated with the nodes that will be added and
removed from the head of the linked list. Each node contains the unique
identifier value associated with the values submitted in the WQEs and
retrieved in the port timestamping CQEs. When a WQE is submitted, the node
in the array corresponding to the identifier popped from the metadata
freelist is added to the end of the CQE pending list and is marked as
"in-use". The node is removed from the linked list under two conditions.
The first condition is that the corresponding port timestamping CQE is
polled in the PTP napi_poll context. The second condition is that more than
a second has elapsed since the DMA timestamp value corresponding to the WQE
submission. When the first condition occurs, the "in-use" bit in the linked
list node is cleared, and the resources corresponding to the WQE submission
are then released. The second condition, however, indicates that the port
timestamping CQE will likely never be delivered. It's not impossible for
the device to post a CQE after an infinite amount of time though highly
improbable. In order to be resilient to this improbable case, resources
related to the corresponding WQE submission are still kept, the identifier
value is not returned to the freelist, and the "in-use" bit is cleared on
the node to indicate that it's no longer part of the linked list of "likely
to be delivered" port timestamping CQE identifiers. A count for the number
of port timestamping CQEs considered highly likely to never be delivered by
the device is maintained. This count gets decremented in the unlikely event
a port timestamping CQE considered unlikely to ever be delivered is polled
in the PTP napi_poll context.

- data segments : 3053 (BG: 3053)
- node segments : 2955 (BG: 2955)
Total GC calls is larger than BGGC calls, the reason is:
- f2fs_stat_info.call_count accounts total migrated section count
by f2fs_gc()
- f2fs_stat_info.bg_gc accounts total call times of f2fs_gc() from
background gc_thread
Another issue is gc_foreground_calls sysfs entry shows total GC call

The commit 25f9080576 ("f2fs: add async reset zone command support")
introduced "async reset zone commands" by calling
__submit_zone_reset_cmd() in async discard operations. However,
__submit_zone_reset_cmd() is called regardless of zone type of discard
target zone. When devices have conventional zones, zone reset commands
are sent to the conventional zones and cause I/O errors.
Avoid the I/O errors by checking that the discard target zone type is
sequential write required. If not, handle the discard operation in same
manner as non-zoned, regular block devices. For that purpose, add a new
helper function f2fs_bdev_index() which gets index of the zone reset
target device.

Shinichiro Kawasaki reported:
When I ran workloads on f2fs using v6.5-rcX with fixes [1][2] and a zoned block
devices with 4kb logical block size, I observe mount failure as follows. When
I revert this commit, the failure goes away.
[ 167.781975][ T1555] F2FS-fs (dm-0): IO Block Size: 4 KB
[ 167.890728][ T1555] F2FS-fs (dm-0): Found nat_bits in checkpoint

[ 171.496000][ T1555] F2FS-fs (dm-0): (0) : Unaligned zone reset attempted (block 280000 + 80000)
[ 171.505037][ T1555] F2FS-fs (dm-0): Discard zone failed: (errno=-5)
The patch replaced "sbi->log_blocksize - SECTOR_SHIFT" with
"sbi->log_sectors_per_block". However, I think these two are not equal when the
device has 4k logical block size. The former uses Linux kernel sector size 512
byte. The latter use 512b sector size or 4kb sector size depending on the
device. mkfs.f2fs obtains logical block size via BLKSSZGET ioctl from the device
and reflects it to the value sbi->log_sector_size_per_block. This causes
unexpected write pointer calculations in check_zone_write_pointer(). This
resulted in unexpected zone reset and the mount failure.

There isn't actually a a690_gmu.bin. But it appears that the normal
a660_gmu.bin works fine. Normally all the devices within a sub-
generation (or "family") will use the same fw, and a690 is in the a660
family.

svc_tcp_sendmsg used to factor in the xdr->page_base when sending pages,
but commit 5df5dd03a8 ("sunrpc: Use sendmsg(MSG_SPLICE_PAGES) rather
then sendpage") dropped that part of the handling. Fix it by setting
the bv_offset of the first bvec.

====================
devlink: introduce selective dumps
Motivation:
For SFs, one devlink instance per SF is created. There might be
thousands of these on a single host. When a user needs to know port
handle for specific SF, he needs to dump all devlink ports on the host
which does not scale good.
Solution:
Allow user to pass devlink handle (and possibly other attributes)
alongside the dump command and dump only objects which are matching
the selection.
Use split ops to generate policies for dump callbacks acccording to
the attributes used for selection.
The userspace can use ctrl genetlink GET_POLICY command to find out if
the selective dumps are supported by kernel for particular command.
Example:
$ devlink port show
auxiliary/mlx5_core.eth.0/65535: type eth netdev eth2 flavour physical port 0 splittable false
auxiliary/mlx5_core.eth.1/131071: type eth netdev eth3 flavour physical port 1 splittable false
$ devlink port show auxiliary/mlx5_core.eth.0
auxiliary/mlx5_core.eth.0/65535: type eth netdev eth2 flavour physical port 0 splittable false
$ devlink port show auxiliary/mlx5_core.eth.1
auxiliary/mlx5_core.eth.1/131071: type eth netdev eth3 flavour physical port 1 splittable false
Extension:
patches #12 and #13 extends selection attributes by port index
for health reporter dumping.

Introduce dumpit callbacks for generated split ops. Have them
as a thin wrapper around iteration function and allow to pass dump_one()
function pointer directly without need to store in devlink_cmd structs.
Note that the function prototypes are temporary until the generated ones
will replace them in a follow-up patch.
