- added clock name and improved clk handling
- fixed binding errors
Changes in v3:
- use readl_poll_timeout_atomic in mdio_wait
- return -ETIMEDOUT, if mdio_wait failed
- added DT binding and changed name to idt,3243x-emac
- fixed usage of of_get_mac_address for net-next

During testing it was found that, with the default FIFO configuration,
a sender which isn't persuaded by our PAUSE frames and keeps sending
will cause some MAC RX frame errors. To mitigate this, we need to ensure
that the FIFO never runs completely full, so we need to fix up a setting

net: enetc: add support for flow control
In the ENETC receive path, a frame received by the MAC is first stored
in a 256KB 'FIFO' memory, then transferred to DRAM when enqueuing it to
the RX ring. The FIFO is a shared resource for all ENETC ports, but
every port keeps track of its own memory utilization, on RX and on TX.
There is a setting for RX rings through which they can either operate in
'lossy' mode (where the lack of a free buffer causes an immediate
discard of the frame) or in 'lossless' mode (where the lack of a free
buffer in the ring makes the frame stay longer in the FIFO).
In turn, when the memory utilization of the FIFO exceeds a certain
margin, the MAC can be configured to emit PAUSE frames.
There is enough FIFO memory to buffer up to 3 MTU-sized frames per RX
port while not jeopardizing the other use cases (jumbo frames), and
also not consume bytes from the port TX allocations. Also, 3 MTU-sized
frames worth of memory is enough to ensure zero loss for 64 byte packets
at 1G line rate.

net: enetc: add a mini driver for the Integrated Endpoint Register Block
The NXP ENETC is a 4-port Ethernet controller which 'smells' to
operating systems like 4 distinct PCIe PFs with SR-IOV, each PF having
its own driver instance, but in fact there are some hardware resources
which are shared between all ports, like for example the 256 KB SRAM
FIFO between the MACs and the Host Transfer Agent which DMAs frames to
DRAM.
To hide the stuff that cannot be neatly exposed per port, the hardware
designers came up with this idea of having a dedicated register block
which is supposed to be populated by the bootloader, and contains
everything configuration-related: MAC addresses, FIFO partitioning, etc.
When a port is reset using PCIe Function Level Reset, its defaults are
transferred from the IERB configuration. Most of the time, the settings
made through the IERB are read-only in the port's memory space (if they
are even visible), so they cannot be modified at runtime.
Linux doesn't have any advanced FIFO partitioning requirements at all,
but when reading through the hardware manual, it became clear that, even
though there are many good 'recommendations' for default values, many of
them were not actually put in practice on LS1028A. So we end up with a
default configuration that:
(a) does not have enough TX and RX byte credits to support the max MTU
of 9600 (which the Linux driver claims already) properly (at full speed)
(b) allows the FIFO to be overrun with RX traffic, potentially
overwriting internal data structures.
The last part sounds a bit catastrophic, but it isn't. Frames are
supposed to transit the FIFO for a very short time, but they can
actually accumulate there under 2 conditions:
(a) there is very severe congestion on DRAM memory, or
(b) the RX rings visible to the operating system were configured for
lossless operation, and they just ran out of free buffers to copy
the frame to. This is what is used to put backpressure onto the MAC
with flow control.
So since ENETC has not supported flow control thus far, RX FIFO overruns
were never seen with Linux. But with the addition of flow control, we
should configure some registers to prevent this from happening. What we
are trying to protect against are bad actors which continue to send us
traffic despite the fact that we have signaled a PAUSE condition. Of
course we can't be lossless in that case, but it is best to configure
the FIFO to do tail dropping rather than letting it overrun.
So in a nutshell, this driver is a fixup for all the IERB default values
that should have been but aren't.
The IERB configuration needs to be done _before_ the PFs are enabled.
So every PF searches for the presence of the "fsl,ls1028a-enetc-ierb"
node in the device tree, and if it finds it, it "registers" with the
IERB, which means that it requests the IERB to fix up its default
values. This is done through -EPROBE_DEFER. The IERB driver is part of
the fsl_enetc module, but is technically a platform driver, since the
IERB is a good old fashioned MMIO region, as opposed to ENETC ports
which pretend to be PCIe devices.
The driver was already configuring ENETC_PTXMBAR (FIFO allocation for
TX) because due to an omission, TXMBAR is a read/write register in the
PF memory space. But the manual is quite clear that the formula for this
should depend upon the TX byte credits (TXBCR). In turn, the TX byte
credits are only readable/writable through the IERB. So if we want to
ensure that the TXBCR register also has a value that is correct and in
line with TXMBAR, there is simply no way this can be done from the PF
driver, access to the IERB is needed.
I could have modified U-Boot to fix up the IERB values, but that is
quite undesirable, as old U-Boot versions are likely to be floating
around for quite some time from now.

Create a common helper that can be used outside of the TSN code for

correct for LS1028A, the only Linux-capable instantiation of ENETC thus
far.
Note that ENETC port 3 is PF 6. The TSN code did not care about this

some struct members adjacent to each other in a single call to
memcpy(). This causes a legitimate compiler warning because memcpy()
overruns the length of &link_usettings.base. Fix this by directly
using &link_usettings and _from_ as destination and source addresses,
instead.
This helps with the ongoing efforts to globally enable -Warray-bounds
and get us closer to being able to tighten the FORTIFY_SOURCE routines
on memcpy().

nexthop: Support large scale nexthop flushing
Patch #1 fixes a day-one bug in the nexthop code and allows "ip nexthop

Patch #2 adds a test case.
Targeting at net-next since this use case never worked, the flow is

netfilter: Dissect flow after packet mangling
Netfilter tries to reroute mangled packets as a different route might
need to be used following the mangling. When this happens, netfilter
does not populate the IP protocol, the source port and the destination
port in the flow key. Therefore, FIB rules that match on these fields
are ignored and packets can be misrouted.
Solve this by dissecting the outer flow and populating the flow key
before rerouting the packet. Note that flow dissection only happens when
FIB rules that match on these fields are installed, so in the common
case there should not be a penalty.

The nftables offload parser sets FLOW_DISSECTOR_KEY_BASIC .n_proto to the

- the original FLOW_DISSECTOR_KEY_VLAN .tpid to the

- the original FLOW_DISSECTOR_KEY_CVLAN .tpid to the .n_proto field.

The statement where an array is being overrun is shown in the following snippet:
if (rate <= DESC_RATE11M)
tx_power = pwr_idx_2g->cck_base[group];
else
====> tx_power = pwr_idx_2g->bw40_base[group];
The associated arrays are defined in main.h as follows:
struct rtw_2g_txpwr_idx {
u8 cck_base[6];
u8 bw40_base[5];
struct rtw_2g_1s_pwr_idx_diff ht_1s_diff;
struct rtw_2g_ns_pwr_idx_diff ht_2s_diff;
struct rtw_2g_ns_pwr_idx_diff ht_3s_diff;
struct rtw_2g_ns_pwr_idx_diff ht_4s_diff;
};
The problem arises because the value of group is 5 for channel 14. The trivial
increase in the dimension of bw40_base fails as this struct must match the layout of
efuse. The fix is to add the rate as an argument to rtw_get_channel_group() and set
the group for channel 14 to 4 if rate <= DESC_RATE11M.

will be restored after an interface down/up cycle, and also when
resuming from suspend. This doesn't seem to provide the best user
experience. Change this to keep user settings, and just ensure that in
jumbo mode pause is disabled.
Small drawback: When switching back mtu from jumbo to non-jumbo then
pause remains disabled (but user can enable it using ethtool).
I think that's a not too common scenario and acceptable.

airo: work around stack usage warning
gcc-11 with KASAN on 32-bit arm produces a warning about a function
that needs a lot of stack space:
drivers/net/wireless/cisco/airo.c: In function 'setup_card.constprop':
drivers/net/wireless/cisco/airo.c:3960:1: error: the frame size of 1512 bytes is larger than 1400 bytes [-Werror=frame-larger-than=]
Most of this is from a single large structure that could be dynamically
allocated or moved into the per-device structure. However, as the callers
all seem to have a fairly well bounded call chain, the easiest change
is to pull out the part of the function that needs the large variables
into a separate function and mark that as noinline_for_stack. This does
not reduce the total stack usage, but it gets rid of the warning and
requires minimal changes otherwise.

mwifiex: don't print SSID to logs
There are a few reasons not to dump SSIDs as-is in kernel logs:
1) they're not guaranteed to be any particular text encoding (UTF-8,
ASCII, ...) in general
2) it's somewhat redundant; the BSSID should be enough to uniquely
identify the AP/STA to which we're connecting
3) BSSIDs have an easily-recognized format, whereas SSIDs do not (they
are free-form)
4) other common drivers (e.g., everything based on mac80211) get along
just fine by only including BSSIDs when logging state transitions
Additional notes on reason #3: this is important for the
privacy-conscious, especially when providing tools that convey
kernel logs on behalf of a user -- e.g., when reporting bugs. So for
example, it's easy to automatically filter logs for MAC addresses, but
it's much harder to filter SSIDs out of unstructured text.

cxl/mem: Fix memory device capacity probing
The CXL Identify Memory Device output payload emits capacity in 256MB
units. The driver is treating the capacity field as bytes. This was
missed because QEMU reports bytes when it should report bytes / 256MB.

====================
mptcp: Fixes and tracepoints from the mptcp tree
Here's one more batch of changes that we've tested out in the MPTCP tree.
Patch 1 makes the MPTCP KUnit config symbol more consistent with other
subsystems.
Patch 2 fixes a couple of format specifiers in pr_debug()s
Patches 3-7 add four helpful tracepoints for MPTCP.
Patch 8 is a one-line refactor to use an available helper macro.
