Add a quirk for a copper SFP that identifies itself as "FS" "SFP-2.5G-T".
This module's PHY is inaccessible, and can only run at 2500base-X with the
host without negotiation. Add a quirk to enable the 2500base-X interface mode
with 2500base-T support and disable auto negotiation.

The Altima AC101L is obviously compatible with the AMD PHY,
as seen by reading the datasheet.

As we don't specify the MTU in the driver, the framework
will fall back to 1500 bytes and this doesn't work very
well when we try to attach a DSA switch:
eth1: mtu greater than device maximum
ixp4xx_eth c800a000.ethernet eth1: error -22 setting
MTU to 1504 to include DSA overhead
I checked the developer docs and the hardware can actually
do really big frames, so update the driver accordingly.

The flexible structure (a structure that contains a flexible-array member
at the end) `qed_ll2_tx_packet` is nested within the second layer of
`struct qed_ll2_info`:
struct qed_ll2_tx_packet {
...
/* Flexible Array of bds_set determined by max_bds_per_packet */
struct {
struct core_tx_bd *txq_bd;
dma_addr_t tx_frag;
u16 frag_len;
} bds_set[];
};
struct qed_ll2_tx_queue {
...
struct qed_ll2_tx_packet cur_completing_packet;
};
struct qed_ll2_info {
...
struct qed_ll2_tx_queue tx_queue;
struct qed_ll2_cbs cbs;
};
The problem is that member `cbs` in `struct qed_ll2_info` is placed just
after an object of type `struct qed_ll2_tx_queue`, which is in itself
an implicit flexible structure, which by definition ends in a flexible
array member, in this case `bds_set`. This causes an undefined behavior
bug at run-time when dynamic memory is allocated for `bds_set`, which
could lead to a serious issue if `cbs` in `struct qed_ll2_info` is
overwritten by the contents of `bds_set`. Notice that the type of `cbs`
is a structure full of function pointers (and a cookie :) ):
include/linux/qed/qed_ll2_if.h:
107 typedef
108 void (*qed_ll2_complete_rx_packet_cb)(void *cxt,
109 struct qed_ll2_comp_rx_data *data);
110
111 typedef
112 void (*qed_ll2_release_rx_packet_cb)(void *cxt,
113 u8 connection_handle,
114 void *cookie,
115 dma_addr_t rx_buf_addr,
116 bool b_last_packet);
117
118 typedef
119 void (*qed_ll2_complete_tx_packet_cb)(void *cxt,
120 u8 connection_handle,
121 void *cookie,
122 dma_addr_t first_frag_addr,
123 bool b_last_fragment,
124 bool b_last_packet);
125
126 typedef
127 void (*qed_ll2_release_tx_packet_cb)(void *cxt,
128 u8 connection_handle,
129 void *cookie,
130 dma_addr_t first_frag_addr,
131 bool b_last_fragment, bool b_last_packet);
132
133 typedef
134 void (*qed_ll2_slowpath_cb)(void *cxt, u8 connection_handle,
135 u32 opaque_data_0, u32 opaque_data_1);
136
137 struct qed_ll2_cbs {
138 qed_ll2_complete_rx_packet_cb rx_comp_cb;
139 qed_ll2_release_rx_packet_cb rx_release_cb;
140 qed_ll2_complete_tx_packet_cb tx_comp_cb;
141 qed_ll2_release_tx_packet_cb tx_release_cb;
142 qed_ll2_slowpath_cb slowpath_cb;
143 void *cookie;
144 };
Fix this by moving the declaration of `cbs` to the middle of its
containing structure `qed_ll2_info`, preventing it from being
overwritten by the contents of `bds_set` at run-time.
This bug was introduced in 2017, when `bds_set` was converted to a
one-element array, and started to be used as a Variable Length Object
(VLO) at run-time.

This issue is caused because usbnet_read_cmd() reads less bytes than requested

This patch fixes the issue by returning -ENODATA if usbnet_read_cmd() reads
less bytes than requested.

ATH10K_SCAN_STARTING state
Scan failure can not be recovered from when running a loop of the
following steps:
1. run scan: "iw wlan scan".
2. run command: echo soft > /sys/kernel/debug/ieee80211/phy0/ath10k/simulate_fw_crash
immediately after step 1.
result:
scan failed and can not recover even when wlan recovery succeeds:
command failed: Device or resource busy (-16)
reason:
When scan arrives, WMI_START_SCAN_CMDID is sent to the firmware and
function ath10k_hw_scan() returns, then simulate_fw_crash arrives
and the scan started event does not arrive, and then it starts to do
recovery of wlan. __ath10k_scan_finish() which is called from
ath10k_halt() is one step of recovery, it will not call
ieee80211_scan_completed() by logic currently because the scan state is
ATH10K_SCAN_STARTING. Thus it leads the scan not being completed in
mac80211, and leads all consecutive scans failing with -EBUSY in
nl80211_trigger_scan even after wlan recovery success.
Indicate scan complete with aborted flag to mac80211 for
ATH10K_SCAN_STARTING to allow recovery from scan failed with "Device or
resource busy (-16)" after wlan recovery.

At the time of the writing, the value of 'num_radar_types' is 7 or 9. So
on a 64 bits system, only 56 or 72 bytes are allocated for the
'detectors' array.
Turn it into a flex array, in order to simplify memory management and save
an indirection when the array is used.
Doing so, cd->detectors can't be NULL, and channel_detector_exit() can be
simplified as well.

If an error occurs and channel_detector_exit() is called, it relies on
entries of the 'detectors' array to be NULL.
Otherwise, it may access to un-initialized memory.
Fix it and initialize the memory, as what was done before the commit in

As talked about in commit d66d24ac300c ("ath10k: Keep track of which
interrupts fired, don't poll them"), if we access the copy engine
register at a bad time then ath10k can go boom. However, it's not
necessarily easy to know when it's safe to access them.
The ChromeOS test labs saw a crash that looked like this at
shutdown/reboot time (on a chromeos-5.15 kernel, but likely the
problem could also reproduce upstream):

Though there's no known way to reproduce the problem, it makes sense
that it would be the same issue where we're trying to access copy
engine registers when it's not allowed.
Let's fix this by changing how we "disable" the interrupts. Instead of
tweaking the copy engine registers we'll just use disable_irq() and
enable_irq(). Then we'll configure the interrupts once at power up
time.

crash
In a special WCN7855 firmware release the EHT (IEEE 802.11be) support has
been disabled for size reduction. Currently ath12k always enables EHT PHY
mode during vdev start but with the special firmware that will cause a
firmware crash during vdev start in firmware initialisation. This is
because the firmware will use the EHT mode to allocate resources but as
the EHT mode is not available in the firmware, there's an internal
conflict and the firmware will crash.
To fix the crash check the WMI_TLV_SERVICE_11BE flag to see if the firmware
supports EHT. If EHT is not supported downgrade the PHY mode to HE
(IEEE 802.11ax).
This does not impact QCN9274, because WMI_SERVICE_11BE is always enabled
for QCN9274, then eht_cap->has_eht will always set for it, and the logic
of this patch will not take effect and the PHY mode will not down grade
for it.

>From 'IEEE Std 802.11-2020 section 11.3.4.1':
If STA A in an infrastructure BSS receives a Class 2 or Class 3 frame
from STA B that is not authenticated with STA A
(i.e., the state for STA B is State 1), STA A shall discard the frame.
If the frame has an individual address in the Address 1 field,
the MLME of STA A shall send a Deauthentication frame to STA B.
When data frames from unassociated stations are received by an AP,
the AP is supposed to send a deauthentication/disassociation frame with
reason code "Class 2 frame received from nonauthenticated STA" or
"Class 3 frame received from nonassociated STA".
But ath12k AP doesn't send deauthentication/disassociation frames,
when it receives data frames from unassociated stations.
The ath12k driver drops the data frames from unassociated
station and the upper layer(mac80211/hostapd) is not aware of such event.
Hence deauthentication/disassociation frame is not sent to that
particular station by the AP.
To address this issue, allow the data frames from the
unassociated stations to reach mac80211 so that mac80211 can send
NL80211_CMD_UNEXPECTED_FRAME event to userspace(hostapd) and hostapd
upon receiving the event will send the deauthentication/disassociation
frame with proper reason code.
The data frame from unassociated stations gets dropped in mac80211.

When the master device is unbinded, make sure to clean up all of the
steering rules or flow tables that were created over the master, in
order to allow proper unbinding of master, and for ethernet traffic
to continue to work independently.
Upon bringing master device back up and attaching the slave to it,
checks if the slave already has IPsec configured and if so reconfigure
the rules needed to support RoCE traffic.
Note that while master device is unbound, the user is unable to
configure IPsec again, since they are in a kind of illegal state in
which they are in MPV mode but the slave has no master.
However if IPsec was configured before hand, it will continue to work
for ethernet traffic while master is unbound, and would continue to
work for all traffic when the master is bound back again.

But in case the traffic is coming from the slave, have to first send the

In the pathological case of building sky2 with 16k PAGE_SIZE, the
frag_addr[] array would never be used, so the original code was correct
that size should be 0. But the compiler now gets upset with 0 size arrays
in places where it hasn't eliminated the code that might access such an
array (it can't figure out that in this case an rx skb with fragments
would never be created). To keep the compiler happy, make sure there is
at least 1 frag_addr in struct rx_ring_info:

Since commit 23d775f12dcd ("net: dsa: mv88e6xxx: Wait for EEPROM done
before HW reset") the following error is seen on a imx8mn board with
a 88E6320 switch:
mv88e6085 30be0000.ethernet-1:00: Timeout waiting for EEPROM done
This board does not have an EEPROM attached to the switch though.
This problem is well explained by Andrew Lunn:
"If there is an EEPROM, and the EEPROM contains a lot of data, it could
be that when we perform a hardware reset towards the end of probe, it
interrupts an I2C bus transaction, leaving the I2C bus in a bad state,
and future reads of the EEPROM do not work.
The work around for this was to poll the EEInt status and wait for it
to go true before performing the hardware reset.
However, we have discovered that for some boards which do not have an
EEPROM, EEInt never indicates complete. As a result,
mv88e6xxx_g1_wait_eeprom_done() spins for a second and then prints a
warning.
We probably need a different solution than calling
mv88e6xxx_g1_wait_eeprom_done(). The datasheet for 6352 documents the
EEPROM Command register:
bit 15 is:
EEPROM Unit Busy. This bit must be set to a one to start an EEPROM
operation (see EEOp below). Only one EEPROM operation can be
executing at one time so this bit must be zero before setting it to
a one. When the requested EEPROM operation completes this bit will
automatically be cleared to a zero. The transition of this bit from
a one to a zero can be used to generate an interrupt (the EEInt in
Global 1, offset 0x00).
and more interesting is bit 11:
Register Loader Running. This bit is set to one whenever the
register loader is busy executing instructions contained in the
EEPROM."
Change to using mv88e6xxx_g2_eeprom_wait() to fix the timeout error
when the EEPROM chip is not present.

Switch to napi_consume_skb() to take advantage of bulk free, and skb
reuse through skb cache in conjunction with napi_build_skb().
When parameter 'budget' = 0, indicating non-NAPI context,
dev_consume_skb_any() is called internally.

Prepare for the coming implementation by GCC and Clang of the __counted_by
attribute. Flexible array members annotated with __counted_by can have
their accesses bounds-checked at run-time checking via CONFIG_UBSAN_BOUNDS
(for array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family
functions).
As found with Coccinelle[1], add __counted_by for struct mt76_rx_tid.

The 5.9/6GHz channel license of a certain platform device has been
regulated in various countries. That may be difference with standard
Liunx regulatory domain settings. In this case, when .reg_notifier()
called for regulatory change, mt792x chipset should update the channel
usage based on clc or dts configurations.
Channel would be disabled by following cases.
* clc report the particular UNII-x is disabled.
* dts enabled and the channel is not configured.

The clc event can report the radio configuration for the corresponding
country and the driver would take it as regulatory information of a
certain platform device.
This patch would change the clc commnad from no-waiting to waiting for
event. For backward compatible, we also add a new nic capability tag
to indicate the firmware did support this new clc event from now on.
