Add parsing support by implementing struct mlx5e_tc_act for police
action.
TC rule with police actions is broken down into several rules in
different tables. One rule with the original match in the original
flow table, which set fte_id, do metering, and jump to the post_meter
table. If there are more police actions, more rules are created for
each of them. Besides, a last rule is created in the end.
In post_meter table, there are two pre-defined rules, one is to drop
packet if its packet color is RED, the other is to jump back to
post_act table. As fte_id is updated before jumping, the rule for next
meter is matched to do another round of metering (if there are
multiple meters in the flow rule). Otherwise, last fte_id is matched
and do the original actions.

Flow meter object monitors the packets rate for the flows it is
attached to, and color packets with GREEN or RED. The post meter table
is used to check the color. Packet is dropped if it's RED, or
forwarded to post_act table if GREEN.
Packet color will be set to 8 LSB of the register C5, so they are
reserved for metering, which are previously used for matching fte id.

Add functions to create and destroy flow meter aso object.
This object only supports the range allocation. 64 objects are
allocated at a time, and there are two meters in each object.
Usually only one meter is allocated for a flow, so bitmap is used
to manage these 128 meters.
TC police action is mapped to hardware meter. As the index is unique
for each police action, add APIs to allocate or free hardware meter by
the index. If the meter is already created, increment its refcnt,
otherwise create new one. If police action has different parameters,
update hardware meter accordingly.

Add a separate API to create SQ and CQ for advanced steering
operations (ASO).
Since the mlx5_en API to create these resources is strongly coupled
with netdev channels and datapath elements, this API provides an
alternative for creating send queues that are used for ASO.
Currently the API allows creating channels with 2 wqbbs only - meaning
the support will be for a single ACCESS_ASO wqe with data at a time.

Currently, there are three eswitch modes, none, legacy and switchdev.
None is the default mode. Remove redundant none mode as eswitch mode
should always be either legacy mode or switchdev mode.
With this patch, there are two behavior changes:
1. Legacy becomes the default mode. When querying eswitch mode using
devlink, a valid mode is always returned.
2. When disabling sriov, the eswitch mode will not change, only vfs
are unloaded.

The ksz9477 and lan937x has few difference in the static and reserved
table register 0x041C. For the ksz9477 if the bit 0 is 1 - read
operation and 0 - write operation. But for lan937x bit 1:0 used for
selecting the read/write operation, 01 - write and 10 - read.
To use ksz9477 mdb add/del and enable_stp_addr for the lan937x, masks &
shifts are introduced for ksz9477 & lan937x in ksz_common.c. Then
updated the function with masks & shifts based on the switch instead of

As stated by Russel King, miic_config() can be called as a result of
ethtool setting the configuration while the link is already up. Since
the speed is also set in this function, it could potentially modify
the current speed that is set. This will only happen if there is
no PHY present and we aren't using fixed-link mode.
Handle that by storing the current interface mode in the miic_port
structure and update the speed only if the interface mode is going to
be changed.

Increase akm_suites array size in struct cfg80211_crypto_settings to 10
and advertise the capability to userspace. This allows userspace to send
more than two AKMs to driver in netlink commands such as
NL80211_CMD_CONNECT.
This capability is needed for implementing WPA3-Personal transition mode
correctly with any driver that handles roaming internally. Currently,
the possible AKMs for multi-AKM connect can include PSK, PSK-SHA-256,
SAE, FT-PSK and FT-SAE. Since the count is already 5, increasing
the akm_suites array size to 10 should be reasonable for future
usecases.

The commit referenced below moved the invocation past the "next" label,
without any explanation. In fact this allows misbehaving backends undue
control over the domain the frontend runs in, as earlier detected errors
require the skb to not be freed (it may be retained for later processing
via xennet_move_rx_slot(), or it may simply be unsafe to have it freed).
This is CVE-2022-33743 / XSA-405.

Bounce all data on the skbs to be transmitted into zeroed pages if the
backend is untrusted. This avoids leaking data present in the pages
shared with the backend but not part of the skb fragments. This
requires introducing a new helper in order to allocate skbs with a
size multiple of XEN_PAGE_SIZE so we don't leak contiguous data on the
granted pages.
Reporting whether the backend is to be trusted can be done using a
module parameter, or from the xenstore frontend path as set by the
toolstack when adding the device.
This is CVE-2022-33741, part of XSA-403.
