As a preparatory patch to add support for a switchdev based cpsw driver,
move common ethtool functions to separate cpsw-ethtool.c file so that they
can be used across both drivers. It will simplify CPSW driver code
maintenance also.

The MAC SL submodule has a lot of common functions between many of TI SoCs
AM335x/AM437x/DRA7(AM57xx), Keystone 2 66AK2HK/E/L/G and K3 AM654, but
there are also differences especially in registers offsets and sets of
supported functions.
This patch introduces the MAC SL submodule API which is intended to provide
a common way to access the MAC SL submodule and hide HW integrations
details.

As a preparatory patch to add a switchdev based cpsw driver move the common
header definitions to cpsw_priv.h. The plan is to develop a new driver on
switchdev driver model and obsolete the current cpsw driver after all
required functions are added to the new driver. This patch allows the same
header file to be re-used on both drivers during the transition period.

The Davinci MDIO in most of the case implemented as module inside of TI
CPSW subsystem and fully depends on CPSW to be enabled, but historically
it's implemented as separate Platform device/driver and defined in DT files
in two ways:
- as standalone node
- as child node of CPSW subsystem.
In later case it's required to split CPSW subsystem "reg" property to
exclude MDIO I/O range which is not useful.
Hence, replace devm_ioremap_resource() with devm_ioremap() to allow define
full I/O range in parent CPSW subsystem without spliting.

Now CPSW ALE will set/clean Host port bit in Unregistered Multicast Flood
Mask (UNREG_MCAST_FLOOD_MASK) for every VLAN without checking if this port
belongs to VLAN or not when ALLMULTI mode flag is set for nedev. This is
working in non dual_mac mode, but in dual_mac - it causes
enabling/disabling ALLMULTI flag for both ports.
Hence fix it by adding additional parameter to cpsw_ale_set_allmulti() to
specify ALE port number for which ALLMULTI has to be enabled and check if
port belongs to VLAN before modifying UNREG_MCAST_FLOOD_MASK.

Add options to strictly validate messages and dump messages,
sometimes perhaps validating dump messages non-strictly may
be required, so add an option for that as well.
Since none of this can really be applied to existing commands,
set the options everwhere using the following spatch:
@@
identifier ops;
expression X;
@@
struct genl_ops ops[] = {
...,
{
.cmd = X,
+ .validate = GENL_DONT_VALIDATE_STRICT | GENL_DONT_VALIDATE_DUMP,
...
},
...
};
For new commands one should just not copy the .validate 'opt-out'
flags and thus get strict validation.

We currently have two levels of strict validation:
1) liberal (default)
- undefined (type >= max) & NLA_UNSPEC attributes accepted
- attribute length >= expected accepted
- garbage at end of message accepted
2) strict (opt-in)
- NLA_UNSPEC attributes accepted
- attribute length >= expected accepted
Split out parsing strictness into four different options:
* TRAILING - check that there's no trailing data after parsing
attributes (in message or nested)
* MAXTYPE - reject attrs > max known type
* UNSPEC - reject attributes with NLA_UNSPEC policy entries
* STRICT_ATTRS - strictly validate attribute size
The default for future things should be *everything*.
The current *_strict() is a combination of TRAILING and MAXTYPE,
and is renamed to _deprecated_strict().
The current regular parsing has none of this, and is renamed to
*_parse_deprecated().
Additionally it allows us to selectively set one of the new flags
even on old policies. Notably, the UNSPEC flag could be useful in
this case, since it can be arranged (by filling in the policy) to
not be an incompatible userspace ABI change, but would then going
forward prevent forgetting attribute entries. Similar can apply
to the POLICY flag.
We end up with the following renames:
* nla_parse -> nla_parse_deprecated
* nla_parse_strict -> nla_parse_deprecated_strict
* nlmsg_parse -> nlmsg_parse_deprecated
* nlmsg_parse_strict -> nlmsg_parse_deprecated_strict
* nla_parse_nested -> nla_parse_nested_deprecated
* nla_validate_nested -> nla_validate_nested_deprecated

For this patch, don't actually add the strict, non-renamed versions
yet so that it breaks compile if I get it wrong.
Also, while at it, make nla_validate and nla_parse go down to a
common __nla_validate_parse() function to avoid code duplication.
Ultimately, this allows us to have very strict validation for every
new caller of nla_parse()/nlmsg_parse() etc as re-introduced in the
next patch, while existing things will continue to work as is.
In effect then, this adds fully strict validation for any new command.

Even if the NLA_F_NESTED flag was introduced more than 11 years ago, most
netlink based interfaces (including recently added ones) are still not
setting it in kernel generated messages. Without the flag, message parsers
not aware of attribute semantics (e.g. wireshark dissector or libmnl's
mnl_nlmsg_fprintf()) cannot recognize nested attributes and won't display
the structure of their contents.
Unfortunately we cannot just add the flag everywhere as there may be
userspace applications which check nlattr::nla_type directly rather than
through a helper masking out the flags. Therefore the patch renames
nla_nest_start() to nla_nest_start_noflag() and introduces nla_nest_start()
as a wrapper adding NLA_F_NESTED. The calls which add NLA_F_NESTED manually
are rewritten to use nla_nest_start().
Except for changes in include/net/netlink.h, the patch was generated using
this semantic patch:
@@ expression E1, E2; @@
-nla_nest_start(E1, E2)
+nla_nest_start_noflag(E1, E2)

The bdinfo handled in hns3_handle_bdinfo is only valid on the
last BD of the current packet, currently the bd info may be handled
based on the first BD if the packet has more than two BDs, which
may cause rx error.
This patch fixes it by using the last BD of the current packet in
hns3_handle_bdinfo.
Also, hns3_set_rx_skb_rss_type has used RSS hash value from the last
BD of the current packet, so remove the same last BD calculation in
hns3_set_rx_skb_rss_type and call it from hns3_handle_bdinfo.

hns3_desc_unused() returns how many BD have been cleaned, but new
buffer has not been attached to them. The register of
HNS3_RING_RX_RING_FBDNUM_REG returns how many BD need allocating new
buffer to or need to cleaned. So the remaining BD need to be clean
is HNS3_RING_RX_RING_FBDNUM_REG - hns3_desc_unused().
Also, new buffer can not attach to the pending BD when the last BD is
not handled, because memcpy has not been done on the first pending BD.
This patch fixes by subtracting the pending BD num from unused_count
after 'HNS3_RING_RX_RING_FBDNUM_REG - unused_count' is used to calculate
the BD bum need to be clean.

PHY's behave differently when being reset. Some reset registers to
defaults, some don't. Some trigger an autoneg restart, some don't.
So let's also set the autoneg restart bit when resetting. Then PHY
behavior should be more consistent. Clearing BMCR_ISOLATE serves the
same purpose and is borrowed from genphy_restart_aneg.
BMCR holds the speed / duplex settings in fixed mode. Therefore
we may have an issue if a soft reset resets BMCR to its default.
So better call genphy_setup_forced() afterwards in fixed mode.
We've seen no related complaint in the last >10 yrs, so let's
treat it as an improvement.

Warning level 3 was used: -Wimplicit-fallthrough=3
Notice that, in this particular case, the code comments are modified
in accordance with what GCC is expecting to find.
This patch is part of the ongoing efforts to enable
-Wimplicit-fallthrough.

When building the L3 HW header for non-IP packets, trust the cast type
that was passed as parameter. qeth_l3_get_cast_type() has most likely
also used h_dest to determine the cast type, so we get the same
result, and can remove that duplicated code.
In the unlikely case that we would get a _different_ cast type, then
that's based off a route lookup and should be considered authoritative.

This de-duplicates the L2 and L3 cast-type code, and makes the L2 code
a bit more robust by removing the fragile assumption that skb->data
always points to the Ethernet Header. This would break in code paths
where we pushed the HW header onto the skb.

The QETH_MAX_BUFFER_ELEMENTS() macro effectively returns a constant
value. To avoid some redundant pointer chasing and computations in the
xmit hot path, cache this value in the queue struct.
Take this as opportunity to shrink some of the queue struct's fields to
their appropriate value range, slightly reducing its total size.

On the first initialization of a queue, its Output Buffers are in a
clean state with no attached resources. On every subsequent
initialization, qeth_l?_stop_card() has previously put them in a clean
state via qeth_drain_output_queues(). So the call to
qeth_clear_output_buffer() is redundant and can be removed.
While at it, move the initialization of the queue's card pointer into
the queue allocation. It never changes afterwards.

We have helper macros for all possible device types, replace all
remaining open-coded accesses to the type fields.

We don't keep track of Input Buffer states, so remove the comments that
make it sound like the qeth_qdio_buffer_states enum applies to
Input Buffers.
