Before "sis900: fix TX completion" patch, TX completion was done on TxIDLE interrupt.
TX completion also was the only thing done on TxIDLE interrupt.
Since "sis900: fix TX completion", TX completion is done on TxDESC interrupt.
So it is not necessary any more to set and to check for TxIDLE.
Eliminate TxIDLE from sis900.
Correct some typos, too.

As other udp/ip tunnels do, tipc udp media should also have a
lockless dst_cache supported on its tx path.
Here we add dst_cache into udp_replicast to support dst cache
for both rmcast and rcast, and rmcast uses ub->rcast and each
rcast uses its own node in ub->rcast.list.

Pull pidfd fixes from Christian Brauner:
"Userspace tools and libraries such as strace or glibc need a cheap and
reliable way to tell whether CLONE_PIDFD is supported. The easiest way
is to pass an invalid fd value in the return argument, perform the
syscall and verify the value in the return argument has been changed
to a valid fd.
However, if CLONE_PIDFD is specified we currently check if pidfd == 0
and return EINVAL if not.
The check for pidfd == 0 was originally added to enable us to abuse
the return argument for passing additional flags along with
CLONE_PIDFD in the future.
However, extending legacy clone this way would be a terrible idea and
with clone3 on the horizon and the ability to reuse CLONE_DETACHED
with CLONE_PIDFD there's no real need for this clutch. So remove the
pidfd == 0 check and help userspace out.
Also, accordig to Al, anon_inode_getfd() should only be used past the
point of no failure and ksys_close() should not be used at all since
it is far too easy to get wrong. Al's motto being "basically, once
it's in descriptor table, it's out of your control". So Al's patch
switches back to what we already had in v1 of the original patchset
and uses a anon_inode_getfile() + put_user() + fd_install() sequence
in the success path and a fput() + put_unused_fd() in the failure
path.
The other two changes should be trivial"

Pull AFS fixes from David Howells:
"The in-kernel AFS client has been undergoing testing on opendev.org on
one of their mirror machines. They are using AFS to hold data that is
then served via apache, and Ian Wienand had reported seeing oopses,
spontaneous machine reboots and updates to volumes going missing. This
patch series appears to have fixed the problem, very probably due to
patch (2), but it's not 100% certain.
(1) Fix the printing of the "vnode modified" warning to exclude checks
on files for which we don't have a callback promise from the
server (and so don't expect the server to tell us when it
changes).
Without this, for every file or directory for which we still have
an in-core inode that gets changed on the server, we may get a
message logged when we next look at it. This can happen in bulk
if, for instance, someone does "vos release" to update a R/O
volume from a R/W volume and a whole set of files are all changed
together.
We only really want to log a message if the file changed and the
server didn't tell us about it or we failed to track the state
internally.
(2) Fix accidental corruption of either afs_vlserver struct objects or
the the following memory locations (which could hold anything).
The issue is caused by a union that points to two different
structs in struct afs_call (to save space in the struct). The call
cleanup code assumes that it can simply call the cleanup for one
of those structs if not NULL - when it might be actually pointing
to the other struct.
This means that every Volume Location RPC op is going to corrupt
something.
(3) Fix an uninitialised spinlock. This isn't too bad, it just causes
a one-off warning if lockdep is enabled when "vos release" is
called, but the spinlock still behaves correctly.
(4) Fix the setting of i_block in the inode. This causes du, for
example, to produce incorrect results, but otherwise should not be
dangerous to the kernel"

Implement net DIM over a generic DIM library, add RDMA DIM
dim.h lib exposes an implementation of the DIM algorithm for
dynamically-tuned interrupt moderation for networking interfaces.
We want a similar functionality for other protocols, which might need to
optimize interrupts differently. Main motivation here is DIM for NVMf
storage protocol.
Current DIM implementation prioritizes reducing interrupt overhead over
latency. Also, in order to reduce DIM's own overhead, the algorithm might
take some time to identify it needs to change profiles. While this is
acceptable for networking, it might not work well on other scenarios.
Here we propose a new structure to DIM. The idea is to allow a slightly
modified functionality without the risk of breaking Net DIM behavior for
netdev. We verified there are no degradations in current DIM behavior with
the modified solution.
Suggested solution:
- Common logic is implemented in lib/dim/dim.c
- Net DIM (existing) logic is implemented in lib/dim/net_dim.c, which uses
the common logic in dim.c
- Any new DIM logic will be implemented in "lib/dim/new_dim.c".
This new implementation will expose modified versions of profiles,
dim_step() and dim_decision().
- DIM API is declared in include/linux/dim.h for all implementations.
Pros for this solution are:
- Zero impact on existing net_dim implementation and usage
- Relatively more code reuse (compared to two separate solutions)
- Increased extensibility

The QCA8337(N) has a RESETn signal on Pin B42 that
triggers a chip reset if the line is pulled low.
The datasheet says that: "The active low duration
must be greater than 10 ms".
This can hopefully fix some of the issues related
to pin strapping in OpenWrt for the EA8500 which
suffers from detection issues after a SoC reset.
Please note that the qca8k_probe() function does
currently require to read the chip's revision
register for identification purposes.

Gateway validation does not need a dst_entry, it only needs the fib
entry to validate the gateway resolution and egress device. So,
convert ip6_nh_lookup_table from ip6_pol_route to fib6_table_lookup
and ip6_route_check_nh to use fib6_lookup over rt6_lookup.
ip6_pol_route is a call to fib6_table_lookup and if successful a call
to fib6_select_path. From there the exception cache is searched for an
entry or a dst_entry is created to return to the caller. The exception
entry is not relevant for gateway validation, so what matters are the
calls to fib6_table_lookup and then fib6_select_path.
Similarly, rt6_lookup can be replaced with a call to fib6_lookup with
RT6_LOOKUP_F_IFACE set in flags. Again, the exception cache search is
not relevant, only the lookup with path selection. The primary difference
in the lookup paths is the use of rt6_select with fib6_lookup versus
rt6_device_match with rt6_lookup. When you remove complexities in the
rt6_select path, e.g.,
1. saddr is not set for gateway validation, so RT6_LOOKUP_F_HAS_SADDR
is not relevant
2. rt6_check_neigh is not called so that removes the RT6_NUD_FAIL_DO_RR
return and round-robin logic.
the code paths are believed to be equivalent for the given use case -
validate the gateway and optionally given the device. Furthermore, it
aligns the validation with onlink code path and the lookup path actually
used for rx and tx.
Adjust the users, ip6_route_check_nh_onlink and ip6_route_check_nh to
handle a fib6_info vs a rt6_info when performing validation checks.
Existing selftests fib-onlink-tests.sh and fib_tests.sh are used to
verify the changes.

FDB, VLAN and PTP fixes for SJA1105 DSA
This patchset is an assortment of fixes for the net-next version of the
sja1105 DSA driver:
- Avoid a kernel panic when the driver fails to probe or unregisters
- Finish Arnd Bermann's idea of compiling PTP support as part of the
main DSA driver and not separately
- Better handling of initial port-based VLAN as well as VLANs for
dsa_8021q FDB entries
- Fix address learning for the SJA1105 P/Q/R/S family
- Make static FDB entries persistent across switch resets
- Fix reporting of statically-added FDB entries in 'bridge fdb show'

The first generation switches don't tell us through the dynamic config
interface whether the dumped FDB entries are static or not (the LOCKEDS
bit from P/Q/R/S).
However, now that we're keeping a mirror of all 'bridge fdb' commands in
the static config, this is an opportunity to compare a dumped FDB entry
to the driver's private database. After all, what makes an entry static
is that *we* added it.

A FDB entry means that "frames that match this VID and DMAC must be
forwarded to this port".
In the case of dsa_8021q however, the VID is not a single one (and
neither two, as my previous patch assumed). The VID can be set either by
the CPU port (1 tx_vid), or by any of the other front-panel port (n-1
rx_vid's).

The reason why this wasn't tackled earlier is that I had hoped I
understood the user manual wrong. But unfortunately hacks are required
in order to retrieve the static/dynamic nature of FDB entries on SJA1105
P/Q/R/S, since this info is stored in the writeback buffer of the
dynamic config command.

After commit 8456721dd4 ("net: dsa: sja1105: Add support for
configuring address ageing time"), we started to reset the switch rather
often (each time the bridge core changes the ageing time on a switch
port).
The unfortunate reality is that SJA1105 doesn't have any {cold, warm,
whatever} reset mode in which it accepts a new configuration stream
without flushing the FDB. Instead, in its world, the FDB *is* an
optional part of the static configuration.
So we play its game, and do what we also do for VLANs: for each 'bridge
fdb' command, we add the FDB entry through the dynamic interface, and we
append the in-kernel static config memory with info that we're going to
use later, when the next reset command is going to be issued.
The result is that 'bridge fdb' commands are now persistent (dynamically
learned entries are lost, but that's ok).

At the end of the commit 1da7382134 ("net: dsa: sja1105: Add FDB
operations for P/Q/R/S series") message, I said that:
At the moment only FDB entries installed statically through 'bridge fdb'
are visible in the dump callback - the dynamically learned ones are
still under investigation.
It looks like the reason why they were not visible in 'bridge fdb' was
that they were never learned - always flooded.
SJA1105 P/Q/R/S manual says about the MAXADDRP[port] field:
Specify the maximum number of MAC address dynamically learned from
the respective port. It is used to limit the number of learned MAC
addresses per port.
It looks like not providing a value in the static config (aka providing
zeroes) is enough for it to not store the learned addresses in the FDB.
For now we divide the 1024 entry FDB "equally" amongst the 5 ports. This
may be revisited if the situation calls for that - for now I'm happy
that learning works.

In SJA1105 there is no concept of 'default values' per se, everything
needs to be driver-supplied through the static configuration tables.
The issue is that the hardware manual says that 'at least the default
untagging VLAN' is mandatory to be provided through the static config.
But VLAN 0 isn't a very good initial pvid - its use is reserved for
priority-tagged frames, and the layers of the stack that care about
those already make sure that this VLAN is installed, as can be seen in
the message below:
8021q: adding VLAN 0 to HW filter on device swp2
So change the pvid provided through the static configuration to 1, which
matches the bridge core's defaults.

As Arnd Bergmann pointed out in commit 78fe8a28fb ("net: dsa: sja1105:

separate loadable kernel module.
So remove the exported symbols and make sja1105.ko contain PTP support
or not based on CONFIG_NET_DSA_SJA1105_PTP.

check and we can also drop the allocation of the txbuf which is part
of the driver data and wastes 256 bytes for no reason. Regmap covers
