All drivers have been converted. Stop using the rxnfc fallbacks
for Rx Flow Hashing configuration.
Joe pointed out in earlier review that in ethtool_set_rxfh()
we need both .get_rxnfc and .get_rxfh_fields, because we need
both the ring count and flow hashing (because we call
ethtool_check_flow_types()). IOW the existing check added
for transitioning drivers was buggy.

Migrate to new callbacks added by commit 9bb00786fc61 ("net: ethtool:

Zeroing data on SET is not necessary, the argument is not copied
back to user space. The driver has no other RXNFC functionality
so the SET callback can be now removed.

Use netmem_dma_*() helpers and declare netmem_tx to support netmem TX.
By this change, all bnxt devices will support the netmem TX.
Unreadable skbs are not going to be handled by the TX push logic.
So, it checks whether a skb is readable or not before the TX push logic.
netmem TX can be tested with ncdevmem.c

The rcar_canfd_f_*() inline functions to obtain channel-specific CAN-FD
register offsets really describe a memory layout. Hence replace them by
a C structure, to simplify the code, and reduce kernel size.
This also gets rid of warnings about unused rcar_canfd_f_*() inline
functions, which are reported by recent versions of clang.

Correct the endianness annotation of port assignments:
A host byte order value (RDS_TCP_PORT) is correctly converted to
network byte order (big endian) using htons. But it is then cast back to
host byte order before assigning to a variable that expects a big endian
value. Address this by dropping the cast.
This is not a bug because, while the endian annotation is changed by
this patch, the assigned value is unchanged.
Also correct the endianness of address assignment.
A host byte order value (INADDR_ANY) is incorrectly assigned as-is to
a variable that expects a big endian value. Address this by converting
the value to network byte order (big endian).
This is not a bug because INADDR_ANY is 0, which is isomorphic
with regards to endian conversions. IOW, while the endian annotation
is changed by this patch, the assigned value is unchanged.
Incorrect endian annotations appear to date back to IPv4-only code added
by commit 70041088e3b9 ("RDS: Add TCP transport to RDS").

gve: XDP TX and redirect support for DQ RDA
A previous patch series[1] introduced the ability to process XDP buffers
to the DQ RDA queue format. This is a follow-up patch series to
introduce XDP_TX and XDP_REDIRECT support and expose XDP support to the
kernel.
Link: https://git.kernel.org/netdev/net-next/c/e2ac75a8a967 [1]

This patch adds support for XDP_TX and XDP_REDIRECT for the DQ RDA
queue format. To appropriately support transmission of XDP frames, a
new pending packet type GVE_TX_PENDING_PACKET_DQO_XDP_FRAME is
introduced for completion handling, as there was a previous assumption
that completed packets would be SKBs.
XDP_TX handling completes the basic XDP actions, so the feature is
recorded accordingly. This patch also enables the ndo_xdp_xmit callback
allowing DQ to handle XDP_REDIRECT packets originating from another
interface.
The XDP spinlock is moved to common TX ring fields so that it can be
used in both GQ and DQ. Originally, it was in a section which was
mutually exclusive for GQ and DQ.
In summary, 3 XDP features are exposed for the DQ RDA queue format:
1) NETDEV_XDP_ACT_BASIC
2) NETDEV_XDP_ACT_NDO_XMIT
3) NETDEV_XDP_ACT_REDIRECT
Note that XDP and header-data split are mutually exclusive for the time
being due to lack of multi-buffer XDP support.
This patch does not add support for the DQ QPL format. That is to come
in a future patch series.

This patch performs various minor DQO TX datapath refactors in
preparation for adding XDP_TX and XDP_REDIRECT support. The following
refactors are performed:
1) gve_tx_fill_pkt_desc_dqo() relies on a SKB pointer to
get whether checksum offloading should be enabled. This won't work
for the XDP case, which does not have a SKB. This patch updates the
method to use a boolean representing whether checksum offloading
should be enabled directly.
2) gve_maybe_stop_dqo() contains some synchronization between the true
TX head and the cached value, a synchronization which is common for
XDP queues and normal netdev queues. However, that method is reserved
for netdev TX queues. To avoid duplicate code, this logic is factored
out into a new method, gve_has_tx_slots_available().
3) gve_tx_update_tail() is added to update the TX tail, a functionality
that will be common between normal TX and XDP TX codepaths.

which branches on queue format.

Currently the call_rcu() API does not check whether a callback
pointer is NULL. If NULL is passed, rcu_core() will try to invoke
it, resulting in NULL pointer dereference and a kernel crash.
To prevent this and improve debuggability, this patch adds a check
for NULL and emits a kernel stack trace to help identify a faulty
caller.

Exit to userspace for TDG.VP.VMCALL<GetTdVmCallInfo> via KVM_EXIT_TDX,
to allow userspace to provide information about the support of
TDVMCALLs when r12 is 1 for the TDVMCALLs beyond the GHCI base API.
GHCI spec defines the GHCI base TDVMCALLs: <GetTdVmCallInfo>, <MapGPA>,
<ReportFatalError>, <Instruction.CPUID>, <#VE.RequestMMIO>,
<Instruction.HLT>, <Instruction.IO>, <Instruction.RDMSR> and
<Instruction.WRMSR>. They must be supported by VMM to support TDX guests.
For GetTdVmCallInfo
- When leaf (r12) to enumerate TDVMCALL functionality is set to 0,
successful execution indicates all GHCI base TDVMCALLs listed above are
supported.
Update the KVM TDX document with the set of the GHCI base APIs.
- When leaf (r12) to enumerate TDVMCALL functionality is set to 1, it
indicates the TDX guest is querying the supported TDVMCALLs beyond
the GHCI base TDVMCALLs.
Exit to userspace to let userspace set the TDVMCALL sub-function bit(s)
accordingly to the leaf outputs. KVM could set the TDVMCALL bit(s)
supported by itself when the TDVMCALLs don't need support from userspace
after returning from userspace and before entering guest. Currently, no
such TDVMCALLs implemented, KVM just sets the values returned from
userspace.

Handle TDVMCALL for GetQuote to generate a TD-Quote.
GetQuote is a doorbell-like interface used by TDX guests to request VMM
to generate a TD-Quote signed by a service hosting TD-Quoting Enclave
operating on the host. A TDX guest passes a TD Report (TDREPORT_STRUCT) in
a shared-memory area as parameter. Host VMM can access it and queue the
operation for a service hosting TD-Quoting enclave. When completed, the
Quote is returned via the same shared-memory area.
KVM only checks the GPA from the TDX guest has the shared-bit set and drops
the shared-bit before exiting to userspace to avoid bleeding the shared-bit
into KVM's exit ABI. KVM forwards the request to userspace VMM (e.g. QEMU)
and userspace VMM queues the operation asynchronously. KVM sets the return
code according to the 'ret' field set by userspace to notify the TDX guest
whether the request has been queued successfully or not. When the request
has been queued successfully, the TDX guest can poll the status field in
the shared-memory area to check whether the Quote generation is completed
or not. When completed, the generated Quote is returned via the same
buffer.
Add KVM_EXIT_TDX as a new exit reason to userspace. Userspace is
required to handle the KVM exit reason as the initial support for TDX,
by reentering KVM to ensure that the TDVMCALL is complete. While at it,
add a note that KVM_EXIT_HYPERCALL also requires reentry with KVM_RUN.

Add the new TDVMCALL status code TDVMCALL_STATUS_SUBFUNC_UNSUPPORTED and
return it for unimplemented TDVMCALL subfunctions.
Returning TDVMCALL_STATUS_INVALID_OPERAND when a subfunction is not
implemented is vague because TDX guests can't tell the error is due to
the subfunction is not supported or an invalid input of the subfunction.
New GHCI spec adds TDVMCALL_STATUS_SUBFUNC_UNSUPPORTED to avoid the
ambiguity. Use it instead of TDVMCALL_STATUS_INVALID_OPERAND.
Before the change, for common guest implementations, when a TDX guest
receives TDVMCALL_STATUS_INVALID_OPERAND, it has two cases:
1. Some operand is invalid. It could change the operand to another value
retry.
2. The subfunction is not supported.
For case 1, an invalid operand usually means the guest implementation bug.
Since the TDX guest can't tell which case is, the best practice for
handling TDVMCALL_STATUS_INVALID_OPERAND is stopping calling such leaf,
treating the failure as fatal if the TDVMCALL is essential or ignoring
it if the TDVMCALL is optional.
With this change, TDVMCALL_STATUS_SUBFUNC_UNSUPPORTED could be sent to
old TDX guest that do not know about it, but it is expected that the
guest will make the same action as TDVMCALL_STATUS_INVALID_OPERAND.
Currently, no known TDX guest checks TDVMCALL_STATUS_INVALID_OPERAND
specifically; for example Linux just checks for success.

The MTUs are negotiated for each direction. In this traces 32767 for
iPhone->localhost and no MTU for localhost->iPhone, which based on
'4.4 L2CAP_CONFIGURATION_REQ' (Core specification v5.4, Vol. 3, Part
A):
The only parameters that should be included in the
L2CAP_CONFIGURATION_REQ packet are those that require different
values than the default or previously agreed values.
...
Any missing configuration parameters are assumed to have their
most recently explicitly or implicitly accepted values.
and '5.1 Maximum transmission unit (MTU)':
If the remote device sends a positive L2CAP_CONFIGURATION_RSP
packet it should include the actual MTU to be used on this channel
for traffic flowing into the local device.
...
The default value is 672 octets.
is set by BlueZ to 672 bytes.
It seems that the iPhone used the lowest negotiated value to transfer
data to the localhost instead of the negotiated one for the incoming
direction.
This could be fixed by using the MTU negotiated for the other
direction, if exists, in the L2CAP_CONFIGURATION_RSP.
This allows to use segmented packets as in the following traces:

A previous fix corrected the retry condition for when to continue a
current bundle, but it missed that the current (not the total) transfer
count also applies to the buffer put. If not, then for incrementally
consumed buffer rings repeated completions on the same request may end
up over consuming.

driver
In the case of SME-in-driver, the driver can internally choose to
update the links based on the AP MLD recommendation and do link
reconfiguration negotiation with AP MLD.
(e.g., After the driver processing the BSS Transition Management request
frame received from the AP MLD with Neighbor Report containing
Multi-Link element with recommended links information chooses to do link
reconfiguration negotiation with AP MLD).
To support this, extend cfg80211_mlo_reconf_add_done() and
NL80211_CMD_ASSOC_MLO_RECONF to indicate added links information for
driver-initiated link reconfiguration requests. For removed links,
the driver indicates links information using the
NL80211_CMD_LINKS_REMOVED event for driver-initiated cases, the same as
supplicant initiated cases.
For the driver-initiated case, cfg80211 will receive link
reconfiguration result asynchronously from driver so holding BSSes of
the accepted add links is needed in the event path. Also, no need of
unhold call for the rejected add link BSSes since there was no hold call
happened previously.
Once the supplicant receives the NL80211_CMD_ASSOC_MLO_RECONF event,
it needs to process the information about newly added links and install
per-link group keys (e.g., GTK/IGTK/BIGTK etc.).
In case of the SME-in-driver, using a vendor interface etc. to notify
the supplicant to initiate a link reconfiguration request and then
supplicant sending command to the cfg80211 can lead to race conditions.
The correct design to avoid this is that the driver indicates the
cfg80211 directly with the results of the link reconfiguration
negotiation.

The existing documentation for the NL80211_CMD_ASSOC_MLO_RECONF
does not clearly explain handling of link reconfiguration request
results from the driver.
Add documentation to explain that the command is used as an event to
notify userspace about added links information, and that the existing
NL80211_CMD_LINKS_REMOVED command is used to notify userspace about
removed links information.

Currently, in ieee80211_assign_beacon() mbssid count is updated as link's
bssid_indicator. mbssid count is the total number of MBSSID elements in
the beacon instead of Max BSSID indicator of the Multiple BSS set.
This will result in drivers obtaining an invalid bssid_indicator for BSSes
in a Multiple BSS set.
Fix this by updating link's bssid_indicator from MBSSID element for
Transmitting BSS and update the same for all of its Non-Transmitting BSSes.

Currently, in multi-radio wiphy cases, if one radio is operating on a DFS
channel, -EBUSY is returned even when a scan is requested on a different
radio. Because of this, an MLD AP with one radio (link) on a DFS channel
and Automatic Channel Selection (ACS) on another radio (link) cannot be
brought up.
In multi-radio wiphy cases, multiple radios are grouped under a single
wiphy. Hence, if a radio is operating on a DFS channel and a scan is
requested on a different radio of the same wiphy, the scan can be allowed
simultaneously without impacting the DFS operations.
Add logic to check the underlying radio used for the requested scan. If the
radio on which DFS is already running is not being used, allow the scan
operation; otherwise, return -EBUSY.
