Add an option to initialize SOF_TIMESTAMPING_OPT_ID for TCP from
write_seq sockets instead of snd_una.

This should have been the behavior from the start. Because processes
may now exist that rely on the established behavior, do not change
behavior of the existing option, but add the right behavior with a new
flag. It is encouraged to always set SOF_TIMESTAMPING_OPT_ID_TCP on
stream sockets along with the existing SOF_TIMESTAMPING_OPT_ID.

Intuitively the contract is that the counter is zero after the
setsockopt, so that the next write N results in a notification for
the last byte N - 1.

On idle sockets snd_una == write_seq and this holds for both. But on
sockets with data in transmission, snd_una records the unacked offset
in the stream. This depends on the ACK response from the peer. A
process cannot learn this in a race free manner (ioctl SIOCOUTQ is one
racy approach).

write_seq records the offset at the last byte written by the process.
This is a better starting point. It matches the intuitive contract in
all circumstances, unaffected by external behavior.

The new timestamp flag necessitates increasing sk_tsflags to 32 bits.
Move the field in struct sock to avoid growing the socket (for some
common CONFIG variants). The UAPI interface so_timestamping.flags is
already int, so 32 bits wide.

mlxsw: Add Spectrum-1 ip6gre support

Ido Schimmel writes:

Currently, mlxsw only supports ip6gre offload on Spectrum-2 and newer
ASICs. Spectrum-1 can also offload ip6gre tunnels, but it needs double
entry router interfaces (RIFs) for the RIFs representing these tunnels.
In addition, the RIF index needs to be even. This is handled in
patches #1-#3.

The implementation can otherwise be shared between all Spectrum
generations. This is handled in patches #4-#5.

Patch #6 moves a mlxsw ip6gre selftest to a shared directory, as ip6gre
is no longer only supported on Spectrum-2 and newer ASICs.

This work is motivated by users that require multiple GRE tunnels that
all share the same underlay VRF. Currently, mlxsw only supports
decapsulation based on the underlay destination IP (i.e., not taking the
GRE key into account), so users need to configure these tunnels with
different source IPs and IPv6 addresses are easier to spare than IPv4.

Tested using existing ip6gre forwarding selftests.

There are two main differences between Spectrum-1 and newer ASICs in
terms of IP-in-IP support:

1. In Spectrum-1, RIFs representing ip6gre tunnels require two entries
   in the RIF table.

2. In Spectrum-2 and newer ASICs, packets ingress the underlay (during
   encapsulation) and egress the underlay (during decapsulation) via a
   special generic loopback RIF.

The first difference was handled in previous patches by adding the
'double_rif_entry' field to the Spectrum-1 operations structure of
ip6gre RIFs. The second difference is handled during RIF creation, by
only creating a generic loopback RIF in Spectrum-2 and newer ASICs.

Therefore, the ip6gre operations can be shared between Spectrum-1 and
newer ASIC in a similar fashion to how the ipgre operations are shared.

Rename the operations to not be Spectrum-2 specific and move them
earlier in the file so that they could later be used for Spectrum-1.

This can happen often with TCP TX zero copy, as one frag usually

====================
Support tc police jump conform-exceed attribute

The tc police action conform-exceed option defines how to handle
packets which exceed or conform to the configured bandwidth limit.
One of the possible conform-exceed values is jump, which skips over
a specified number of actions.
This series adds support for conform-exceed jump action.

The series adds platform support for branching actions by providing
true/false flow attributes to the branching action.
This is necessary for supporting police jump, as each branch may
execute a different action list.

The first five patches are preparation patches:
- Patches 1 and 2 add support for actions with no destinations (e.g. drop)
- Patch 3 refactor the code for subsequent function reuse
- Patch 4 defines an abstract way for identifying terminating actions
- Patch 5 updates action list validations logic considering branching actions

The following three patches introduce an interface for abstracting branching
actions:
- Patch 6 introduces an abstract api for defining branching actions
- Patch 7 generically instantiates the branching flow attributes using
  the abstract API

Patch 8 adds the platform support for jump actions, by executing the following
sequence:
  a. Store the jumping flow attr
  b. Identify the jump target action while iterating the actions list.
  c. Instantiate a new flow attribute after the jump target action.
     This is the flow attribute that the branching action should jump to.
  d. Set the target post action id on:
    d.1. The jumping attribute, thus realizing the jump functionality.
    d.2. The attribute preceding the target jump attr, if not terminating.

The next patches apply the platform's branching attributes to the police
action:
- Patch 9 is a refactor patch
- Patch 10 initializes the post meter table with the red/green flow attributes,
           as were initialized by the platform
- Patch 11 enables the offload of meter actions using jump conform-exceed
           value.

hid-logitech-hidpp, and the end result is that the probe of those mice
is now returning -ENODEV, leaving the end user with a dead mouse.

Given that commit 8544c812 ("HID: logitech-hidpp: Remove special-casing
of Bluetooth devices") is a direct dependency of 532223c8, revert it
too.

Note that this also adapt according to commit 908d325e ("HID:
logitech-hidpp: Detect hi-res scrolling support") to re-add support of
the devices that were removed from that commit too.

I have locally an MX Master and I tested this device with that revert,
ensuring we still have high-res scrolling.
