Existing match criteria didn't allow to match whole subnet and
only by specific addresses only. This caused to tunnel mode do not
forward such traffic through relevant SA.
In tunnel mode, policies look like this:
src 192.169.0.0/16 dst 192.169.0.0/16
dir out priority 383615 ptype main
tmpl src 192.169.101.2 dst 192.169.101.1
proto esp spi 0xc5141c18 reqid 1 mode tunnel
crypto offload parameters: dev eth2 mode packet
In this case, the XFRM core code handled all subnet calculations and
forwarded network address to the drivers e.g. 192.169.0.0.
For mlx5 devices, there is a need to set relevant prefix e.g. 0xFFFF00
to perform flow steering match operation.

Patch [1] added mlx5 driver support for 8 ports HCAs which are available
since ConnectX-8. Now that Multiport E-Switch is tested, we can enable
it by removing flag MLX5_LAG_MPESW_OFFLOADS_SUPPORTED_PORTS.

Currently, when auto-negotiation is disabled, the driver retrieves
the speed and converts it into all link modes that correspond to
that speed. With this patch, we add the ability to set the number
of lanes, so that the combination of speed and lanes corresponds to
exactly one specific link mode for the extended bit map.
For the legacy bit map the driver sets all link modes correspond to
speed and lanes.
This change provides users with the option to set a specific link
mode, rather than enabling all link modes associated with a given
speed when auto-negotiation is off.

Introduce struct mlx5_link_info with a speed field and change the
types of mlx5e_link_speed and mlx5e_ext_link_speed from arrays of
u32 to arrays of struct mlx5_link_info. These arrays are renamed
to mlx5e_link_info and mlx5e_ext_link_info, respectively.
This change prepares for a future patch that will introduce a lanes
field in struct mlx5_link_info and add lanes mapping alongside the
speed for each link mode in the two arrays.
Additionally, rename function mlx5_port_speed2linkmodes() to
mlx5_port_info2linkmodes() and function mlx5_port_ptys2speed()
to mlx5_port_ptys2info() and update the speed parameter/return
type to struct mlx5_link_info, in preparation for the upcoming
patch where these functions will also utilize the lanes field.

The port header is a general file under include, yet it
contains declarations for functions that are either not
exported or exported but not used outside the mlx5_core
driver.
To enhance code organization, we move these declarations
to mlx5_core.h, where they are more appropriately scoped.
This refactor removes unnecessary exported symbols and
prevents unexported functions from being inadvertently
referenced outside of the mlx5_core driver.

icss_iep_perout_enable_hw() is a common function for generating
both pps and perout signals. When enabling pps, the application needs
to only pass enable/disable argument, whereas for perout it supports
different flags to configure the signal.
In case the app passes a valid phase offset value, the signal should
start toggling after that phase offset, else start immediately or
as soon as possible. ICSS_IEP_SYNC_START_REG register take number of
clock cycles to wait before starting the signal after activation time.
Set appropriate value to this register to support phase offset.

is also one feature which can configured for perout, incorporate this
in the function to get the expected signal.

Currently, the calls to phylink's suspend and resume functions are
inside overly complex tests, and boil down to:
if (device_may_wakeup(priv->device) && priv->plat->pmt) {
call phylink
} else {
call phylink and
if (device_may_wakeup(priv->device))
do something else
}
This results in phylink always being called, possibly with differing
arguments for phylink_suspend().
Simplify this code, noting that each site is slightly different due to
the order in which phylink is called and the "something else".

Only devlink and sriov paths are grabbing rtnl explicitly. The rest is
covered by netdev instance lock which the core now grabs, so there is
no need to manage rtnl in most places anymore.
On the core side we can now try to drop rtnl in some places
(do_setlink for example) for the drivers that signal non-rtnl
mode (TBD).

For the drivers that use shaper API, switch to the mode where
core stack holds the netdev lock. This affects two drivers:
* iavf - already grabs netdev lock in ndo_open/ndo_stop, so mostly
remove these
* netdevsim - switch to _locked APIs to avoid deadlock
iavf_close diff is a bit confusing, the existing call looks like this:
iavf_close() {
netdev_lock()
..
netdev_unlock()
wait_event_timeout(down_waitqueue)
}
I change it to the following:
netdev_lock()
iavf_close() {
..
netdev_unlock()
wait_event_timeout(down_waitqueue)
netdev_lock() // reusing this lock call
}
netdev_unlock()
Since I'm reusing existing netdev_lock call, so it looks like I only
add netdev_unlock.

When the XDP metadata area was used, it is expected that the same
metadata can also be accessed from TC, as can be read in the description
of the bpf_xdp_adjust_meta helper function. In the tun driver, this was
not yet implemented.
To make this work, the skb that is being built on XDP_PASS should know
of the current size of the metadata area. This is ensured by adding
calls to skb_metadata_set. For the tun_xdp_one code path, an additional
check is necessary to handle the case where the externally initialized
xdp_buff has no metadata support (xdp->data_meta == xdp->data + 1).
More information about this feature can be found in the commit message
of commit de8f3a83b0a0 ("bpf: add meta pointer for direct access").

Enable the support for the bpf_xdp_adjust_meta helper function for XDP
buffers initialized by the tun driver. This allows to reserve a metadata
area that is useful to pass any information from one XDP program to
another one, for example when using tail-calls.
Whether this helper function can be used in an XDP program depends on
how the xdp_buff was initialized. Most net drivers initialize the
xdp_buff in a way, that allows bpf_xdp_adjust_meta to be used. In case
of the tun driver, this is currently not the case.
There are two code paths in the tun driver that lead to a
bpf_prog_run_xdp and where metadata support should be enabled:
1. tun_build_skb, which is called by tun_get_user and is used when
writing packets from userspace into the device. In this case, the
xdp_buff created in tun_build_skb has no support for
bpf_xdp_adjust_meta and calls of that helper function result in
ENOTSUPP.
For this code path, it's sufficient to set the meta_valid argument of
the xdp_prepare_buff call. The reserved headroom is large enough
already.
2. tun_xdp_one, which is called by tun_sendmsg which again is called by
other drivers (e.g. vhost_net). When the TUN_MSG_PTR mode is used,
another driver may pass a batch of xdp_buffs to the tun driver. In
this case, that other driver is the one initializing the xdp_buff.
See commit 043d222f93ab ("tuntap: accept an array of XDP buffs
through sendmsg()") for details.
For now, the vhost_net driver is the only one using TUN_MSG_PTR and
it already initializes the xdp_buffs with metadata support and
sufficient headroom. But the tun driver disables it again, so the
xdp_set_data_meta_invalid call has to be removed.

daddr can be NULL if there is no neighbour table entry present,
in that case the tx packet should be dropped.
saddr will usually be set by MCTP core, but check for NULL in case a
packet is transmitted by a different protocol.

On MMIO devices (e.g. MT7988 or EN7581) unicast traffic received on lanX
port is flooded on all other user ports if the DSA switch is configured
without VLAN support since PORT_MATRIX in PCR regs contains all user
ports. Similar to MDIO devices (e.g. MT7530 and MT7531) fix the issue
defining default VLAN-ID 0 for MT7530 MMIO devices.

Intel platform will configure the SerDes through PMC API based on the
provided interface mode.
This patch adds several new functions below:-
- intel_tsn_lane_is_available(): This new function reads FIA lane
ownership registers and common lane registers through IPC commands
to know which lane the mGbE port is assigned to.
- intel_mac_finish(): To configure the SerDes based on the assigned
lane and latest interface mode, it sends IPC command to the PMC through
PMC driver/API. The PMC acts as a proxy for R/W on behalf of the driver.
- intel_set_reg_access(): Set the register access to the available TSN
interface.

The xpcs_switch_interface_mode function was introduced to handle
interface switching.
According to the XPCS datasheet, a soft reset is required to initiate
Clause 37 auto-negotiation when the XPCS switches interface modes.
When the interface mode switches from 2500BASE-X to SGMII,
re-initiating Clause 37 auto-negotiation is required for the SGMII
interface mode to function properly.

The phylink_expects_phy() function allows MAC drivers to check if they are
expecting a PHY to attach. The checking condition in phylink_expects_phy()
aims to achieve the same result as the checking condition in
phylink_attach_phy().
However, the checking condition in phylink_expects_phy() uses
pl->link_config.interface, while phylink_attach_phy() uses
pl->link_interface.
Initially, both pl->link_interface and pl->link_config.interface are set
to SGMII, and pl->cfg_link_an_mode is set to MLO_AN_INBAND.
When the interface switches from SGMII to 2500BASE-X,
pl->link_config.interface is updated by phylink_major_config().
At this point, pl->cfg_link_an_mode remains MLO_AN_INBAND, and
pl->link_config.interface is set to 2500BASE-X.
Subsequently, when the STMMAC interface is taken down
administratively and brought back up, it is blocked by
phylink_expects_phy().
Since phylink_expects_phy() and phylink_attach_phy() aim to achieve the
same result, phylink_expects_phy() should check pl->link_interface,
which never changes, instead of pl->link_config.interface, which is
updated by phylink_major_config().

ice_health_init() was introduced in the commit 2a82874a3b7b ("ice: add
Tx hang devlink health reporter"). The call to it should have been put
after ice_devlink_register(). It went unnoticed until next reporter by
Konrad, which receives events from FW. FW is reporting all events, also
from prior driver load, and thus it is not unlikely to have something
at the very beginning. And that results in a splat:
[ 24.455950] ? devlink_recover_notify.constprop.0+0x198/0x1b0
[ 24.455973] devlink_health_report+0x5d/0x2a0
[ 24.455976] ? __pfx_ice_health_status_lookup_compare+0x10/0x10 [ice]
[ 24.456044] ice_process_health_status_event+0x1b7/0x200 [ice]
Do the analogous thing for deinit patch.
