soc: qcom: ipa: kill IPA_RX_BUFFER_ORDER

Don't assume the receive buffer size is a power-of-2 number of pages.
Instead, define the receive buffer size independently, and then
compute the page order from that size when needed.

This fixes a build problem that arises when the ARM64_PAGE_SHIFT
config option is set to have a page size greater than 4KB.  The
problem was identified by Linux Kernel Functional Testing.

The IPA code basically assumed the page size to be 4KB.  A larger page
size caused the receive buffer size to become correspondingly larger
(32KB or 128KB for ARM64_16K_PAGES and ARM64_64K_PAGES, respectively).
The receive buffer size is used to compute an "aggregation byte limit"
value that gets programmed into the hardware, and the large page sizes
caused that limit value to be too big to fit in a 5 bit field.  This
triggered a BUILD_BUG_ON() call in ipa_endpoint_validate_build().

This fix causes a lot of receive buffer memory to be wasted if
system is configured for page size greater than 4KB.  But such a
misguided configuration will now build successfully.

net: dsa: sja1105: Add support for the SGMII port

SJA1105 switches R and S have one SerDes port with an 802.3z
quasi-compatible PCS, hardwired on port 4. The other ports are still
MII/RMII/RGMII. The PCS performs rate adaptation to lower link speeds;
the MAC on this port is hardwired at gigabit. Only full duplex is
supported.

The SGMII port can be configured as part of the static config tables, as
well as through a dedicated SPI address region for its pseudo-clause-22
registers. However it looks like the static configuration is not
able to change some out-of-reset values (like the value of MII_BMCR), so
at the end of the day, having code for it is utterly pointless. We are
just going to use the pseudo-C22 interface.

Because the PCS gets reset when the switch resets, we have to add even
more restoration logic to sja1105_static_config_reload, otherwise the
SGMII port breaks after operations such as enabling PTP timestamping
which require a switch reset.

>From PHYLINK perspective, the switch supports *only* SGMII (it doesn't
support 1000Base-X). It also doesn't expose access to the raw config
word for in-band AN in registers MII_ADV/MII_LPA.
It is able to work in the following modes:
 - Forced speed
 - SGMII in-band AN slave (speed received from PHY)
 - SGMII in-band AN master (acting as a PHY)

The latter mode is not supported by this patch. It is even unclear to me
how that would be described. There is some code for it left in the
patch, but 'an_master' is always passed as false.

cfg80211: Configure PMK lifetime and reauth threshold for PMKSA entries

Drivers that trigger roaming need to know the lifetime of the configured
PMKSA for deciding whether to trigger the full or PMKSA cache based
authentication. The configured PMKSA is invalid after the PMK lifetime
has expired and must not be used after that and the STA needs to
disassociate if the PMK expires. Hence the STA is expected to refresh
the PMK with a full authentication before this happens (e.g., when
reassociating to a new BSS the next time or by performing EAPOL
reauthentication depending on the AKM) to avoid unnecessary
disconnection.

The PMK reauthentication threshold is the percentage of the PMK lifetime
value and indicates to the driver to trigger a full authentication roam
(without PMKSA caching) after the reauthentication threshold time, but
before the PMK timer has expired. Authentication methods like SAE need
to be able to generate a new PMKSA entry without having to force a
disconnection after this threshold timeout. If no roaming occurs between
the reauthentication threshold time and PMK lifetime expiration,
disassociation is still forced.

The new attributes for providing these values correspond to the dot11
MIB variables dot11RSNAConfigPMKLifetime and
dot11RSNAConfigPMKReauthThreshold.

This type of functionality is already available in cases where user
space component is in control of roaming. This commit extends that same
capability into cases where parts or all of this functionality is
offloaded to the driver.

nl80211: add no pre-auth attribute and ext. feature flag for ctrl. port

If the nl80211 control port is used before this patch, pre-auth frames
(0x88c7) are send to userspace uncoditionally. While this enables userspace
to only use nl80211 on the station side, it is not always useful for APs.
Furthermore, pre-auth frames are ordinary data frames and not related to
the control port. Therefore it should for example be possible for pre-auth
frames to be bridged onto a wired network on AP side without touching
userspace.

For backwards compatibility to code already using pre-auth over nl80211,
this patch adds a feature flag to disable this behavior, while it remains
enabled by default. An additional ext. feature flag is added to detect this
from userspace.

the skbedit priority gadget. This patchset therefore implements offloading
of this action to the Spectrum ACL engine.

to support offloading of "priority" subcommand.

net: bridge: vlan: include stats in dumps if requested

This patch adds support for vlan stats to be included when dumping vlan
information. We have to dump them only when explicitly requested (thus the
flag below) because that disables the vlan range compression and will make
the dump significantly larger. In order to request the stats to be
included we add a new dump attribute called BRIDGE_VLANDB_DUMP_FLAGS which
can affect dumps with the following first flag:
  - BRIDGE_VLANDB_DUMPF_STATS
The stats are intentionally nested and put into separate attributes to make
it easier for extending later since we plan to add per-vlan mcast stats,
drop stats and possibly STP stats. This is the last missing piece from the
new vlan API which makes the dumped vlan information complete.

A dump request which should include stats looks like:
 [BRIDGE_VLANDB_DUMP_FLAGS] |= BRIDGE_VLANDB_DUMPF_STATS

A vlandb entry attribute with stats looks like:
 [BRIDGE_VLANDB_ENTRY] = {
     [BRIDGE_VLANDB_ENTRY_STATS] = {
         [BRIDGE_VLANDB_STATS_RX_BYTES]
         [BRIDGE_VLANDB_STATS_RX_PACKETS]

net: sched: Fix hw_stats_type setting in pedit loop

In the commit referenced below, hw_stats_type of an entry is set for every
entry that corresponds to a pedit action. However, the assignment is only
done after the entry pointer is bumped, and therefore could overwrite
memory outside of the entries array.

The reason for this positioning may have been that the current entry's
hw_stats_type is already set above, before the action-type dispatch.
However, if there are no more actions, the assignment is wrong. And if
there are, the next round of the for_each_action loop will make the
assignment before the action-type dispatch anyway.

Therefore fix this issue by simply reordering the two lines.

1. High Priority (HPFILTER) region (Highest Priority).
2. HASH region.
3. Normal FILTER region (Lowest Priority).

Currently, there's a 1-to-1 mapping between the prio value passed
by TC and the filter region index. However, it's possible to have
multiple TC rules with the same prio value. In this case, if a region
is exhausted, no attempt is made to try inserting the rule in the
next available region.

So, rework and remove the 1-to-1 mapping. Instead, dynamically select
the region to insert the filter rule, as long as the new rule's prio
value doesn't conflict with existing rules across all the 3 regions.

and statistics. This patch-set takes care of the former by making it a

 - vlan range to tunnel range mapping
   * The tunnel ids are globally unique for the vlan code and a vlan can
     be mapped to one tunnel, so the old API took care of ranges by
     taking the starting tunnel id value and incrementally mapping
     vlan id(i) -> tunnel id(i). This set takes the same approach and
     uses one new attribute - BRIDGE_VLANDB_ENTRY_TUNNEL_ID. If used
     with a vlan range then it's the starting tunnel id to map.

 - tunnel mapping removal

     encode mapping removal within the new attribute, in order to be
     able to remove a mapping we add a vlan flag which makes the new
     tunnel option remove the mapping

The rest is pretty straight-forward, in fact we directly re-use the old
code for manipulating tunnels by just mapping the command (set/del). In
order to be able to keep detecting vlan ranges we check that the current

attribute for the tunnel range end. It's simply base tunnel id + vlan
range. And second to support removing mappings we need an out-of-band way
to tell the option manipulating function because there are no
