net: dsa: mv88e6xxx: add Amethyst specific SMI GPIO function
Amethyst family (MV88E6191X/6193X/6393X) has a simplified SMI GPIO setting
via the Scratch and Misc register so it requires family specific function.
In the v1 review, Andrew pointed out that it would make sense to rename the
existing mv88e6xxx_g2_scratch_gpio_set_smi as it only works on the MV6390
family.
Changes in v2:
* Add rename of mv88e6xxx_g2_scratch_gpio_set_smi to
mv88e6390_g2_scratch_gpio_set_smi

The existing mv88e6390_g2_scratch_gpio_set_smi() cannot be used on the
88E6393X as it requires certain P0_MODE, it also checks the CPU mode
as it impacts the bit setting value.
This is all irrelevant for Amethyst (MV88E6191X/6193X/6393X) as only
the default value of the SMI_PHY Config bit is set to CPU_MGD bootstrap
pin value but it can be changed without restrictions so that GPIO pins
9 and 10 are used as SMI pins.
So, introduce Amethyst specific function and call that if the Amethyst
family wants to setup the external PHY.

====================
tools: ynl: stop using libmnl
There is no strong reason to stop using libmnl in ynl but there
are a few small ones which add up.
First (as I remembered immediately after hitting send on v1),
C++ compilers do not like the libmnl for_each macros.
I haven't tried it myself, but having all the code directly
in YNL makes it easier for folks porting to C++ to modify them
and/or make YNL more C++ friendly.
Second, we do much more advanced netlink level parsing in ynl
than libmnl so it's hard to say that libmnl abstracts much from us.
The fact that this series, removing the libmnl dependency, only
adds <300 LoC shows that code savings aren't huge.
OTOH when new types are added (e.g. auto-int) we need to add
compatibility to deal with older version of libmnl (in fact,
even tho patches have been sent months ago, auto-ints are still
not supported in libmnl.git).
Thrid, the dependency makes ynl less self contained, and harder
to vendor in. Whether vendoring libraries into projects is a good
idea is a separate discussion, nonetheless, people want to do it.
Fourth, there are small annoyances with the libmnl APIs which
are hard to fix in backward-compatible ways. See the last patch
for example.
All in all, libmnl is a great library, but with all the code
generation and structured parsing, ynl is better served by going
its own way.

All callers to mnl_cb_run2() call mnl_socket_recvfrom() right before.
Wrap the two in a helper, take typed arguments (struct ynl_parse_arg),
instead of hoping that all callers remember that parser error handling
requires yarg.
In case of ynl_sock_read_family() we will no longer check for kernel
returning no data, but that would be a kernel bug, not worth complicating
the code to catch this. Calling mnl_cb_run2() on an empty buffer
is legal and results in STOP (1).

drivers: net: Convert EEE handling to use linkmode bitmaps
EEE has until recently been limited to lower speeds due to the use of
the legacy u32 for link speeds. This restriction has been lifted, with
the use of linkmode bitmaps, added in the following patches:
1f069de636 ethtool: add linkmode bitmap support to struct ethtool_keee
1d756ff13d ethtool: add suffix _u32 to legacy bitmap members of struct ethtool_keee
285cc15cc5 ethtool: adjust struct ethtool_keee to kernel needs
0b3100bc8f ethtool: switch back from ethtool_keee to ethtool_eee for ioctl
d80a523353 ethtool: replace struct ethtool_eee with a new struct ethtool_keee on kernel side
This patchset converts the remaining MAC drivers still using the old
_u32 to link modes.
A couple of Intel drivers do odd things with EEE, setting the autoneg
bit. It is unclear why, no other driver does, ethtool does not display
it, and EEE is always negotiated. One patch in this series deletes
this code.
With all users of the legacy _u32 changed to link modes, the _u32
values are removed from keee, and support for them in the ethtool core
is removed.

modes, rather than u32 values.
Rework determining if EEE is active to make is similar as to how
phylib decides, and make use of a phylib helper to validate if EEE is
valid in for the current link mode. This then requires that PHYLIB is
selected.

The input parameter 'level' in rawv6_get/seticmpfilter is not used.
Therefore, remove it.

Updating link clock rate for different speeds is only needed when
using RGMII, as that mode requires changing clock speed when the link
speed changes. Let's restrict updating the link clock speed in
ethqos_update_link_clk() to just RGMII. Other modes such as SGMII
only need to enable the link clock (which is already done in probe).

Justin Iurman says:
====================
ioam6: netlink multicast event
v5:
- remove the "must be the destination" check before sending an ioam6
event
v4:
- rebase on top of net merge
v3:
- patchset was mistakenly superseded due to same cover title used for
iproute2-next equivalent patch -> resend (renamed)
v2:
- fix warnings
Add generic netlink multicast event support to ioam6 as another solution
to share IOAM data with user space. The other one being via IPv6 raw
sockets combined with ancillary data (or packet socket, if the listener
does not need the processing of the IOAM Option-Type, since the hook is
before in that case). This patchset focuses on the IOAM Pre-allocated
Trace (the only Option-Type currently supported in the kernel), and so
on IOAM "trace" events. See an example of a consumer here [1].

If we're processing an IOAM Pre-allocated Trace Option-Type (the only
one supported currently), then send the trace as an ioam6 event to the
netlink multicast group. This way, user space apps will be able to
collect IOAM data.

Add a multicast group to the ioam6 generic netlink family and provide
ioam6_event() to send an ioam6 event to the multicast group.

Add new api to support ioam6 events for generic netlink multicast. A
first "trace" event is added to the list of ioam6 events, which will
represent an IOAM Pre-allocated Trace Option-Type. It provides another
solution to share IOAM data with user space.
