The 'mptcp_subflow_context' structure has two items related to the
backup flags:
- 'backup': the subflow has been marked as backup by the other peer
- 'request_bkup': the backup flag has been set by the host
Before this patch, the scheduler was only looking at the 'backup' flag.
That can make sense in some cases, but it looks like that's not what we
wanted for the general use, because either the path-manager was setting
both of them when sending an MP_PRIO, or the receiver was duplicating
the 'backup' flag in the subflow request.
Note that the use of these two flags in the path-manager are going to be
fixed in the next commits, but this change here is needed not to modify
the behaviour.

mptcp: fix signal endpoint readd
Issue #501 [1] showed that the Netlink PM currently doesn't correctly
support removal and re-add of signal endpoints.
Patches 1 and 2 address the issue: the first one in the userspace path-
manager, introduced in v5.19 ; and the second one in the in-kernel path-
manager, introduced in v5.7.
Patch 3 introduces a related selftest. There is no 'Fixes' tag, because
it might be hard to backport it automatically, as missing helpers in
Bash will not be caught when compiling the kernel or the selftests.
The last two patches address two small issues in the MPTCP selftests,
one introduced in v6.6., and the other one in v5.17.

tp->scaling_ratio is not updated based on skb->len/skb->truesize once
SO_RCVBUF is set leading to the maximum window scaling to be 25% of
rcvbuf after
commit dfa2f0483360 ("tcp: get rid of sysctl_tcp_adv_win_scale")
and 50% of rcvbuf after
commit 697a6c8cec03 ("tcp: increase the default TCP scaling ratio").
50% tries to emulate the behavior of older kernels using
sysctl_tcp_adv_win_scale with default value.
Systems which were using a different values of sysctl_tcp_adv_win_scale
in older kernels ended up seeing reduced download speeds in certain
cases as covered in https://lists.openwall.net/netdev/2024/05/15/13
While the sysctl scheme is no longer acceptable, the value of 50% is
a bit conservative when the skb->len/skb->truesize ratio is later
determined to be ~0.66.
Applications not specifying SO_RCVBUF update the window scaling and
the receiver buffer every time data is copied to userspace. This
computation is now used for applications setting SO_RCVBUF to update
the maximum window scaling while ensuring that the receive buffer
is within the application specified limit.

We expect drivers implementing the new create/modify/destroy
API to populate the defaults in struct ethtool_rxfh_context.
In legacy API ctx isn't even passed, and rxfh.indir / rxfh.key
are NULL so drivers can't give us defaults even if they want to.
Call get_rxfh() to fetch the values. We can reuse rxfh_dev
for the get_rxfh(), rxfh stores the input from the user.

the only one to check for S390 to be n, all others had checked for !S390.
Since it is a boolean and not a tristate I am not sure it will be N. So
just update it to use the !S390 flag.
A quick check via "make menuconfig" verified that after making this change
there was an option to select the fbnic driver.

The PHY built in to the Realtek RTL8366S switch controller was
previously supported by genphy_driver. This PHY does not implement MMD
operations. Since commit 9b01c885be36 ("net: phy: c22: migrate to
genphy_c45_write_eee_adv()"), MMD register reads have been made during
phy_probe to determine EEE support. For genphy_driver, these reads are
transformed into 802.3 annex 22D clause 45-over-clause 22
mmd_phy_indirect operations that perform MII register writes to
MII_MMD_CTRL and MII_MMD_DATA. This overwrites those two MII registers,
which on this PHY are reserved and have another function, rendering the
PHY unusable while so configured.
Proper support for this PHY is restored by providing a phy_driver that
declares MMD operations as unsupported by using the helper functions
provided for that purpose, while remaining otherwise identical to
genphy_driver.

The ext interrupts are enabled when the firmware has been started, but
this may never happen, for example, if the board configuration file is
missing.
When the system is later suspended, the driver unconditionally tries to
disable interrupts, which results in an irq disable imbalance and causes
the driver to spin indefinitely in napi_synchronize().
Make sure that the interrupts have been enabled before attempting to
disable them.

However, if the driver didn't also have the WANT_MONITOR flag
this would cause mac80211 to allocate it without telling the
driver (which was intentional) but also use it for later APIs
to the driver without it ever having known about it which was
_not_ intentional.
Check through the code and only use the monitor_sdata in the

It could lead to error happen because the variable res is not updated if
the call to sr_share_read_word returns an error. In this particular case
error code was returned and res stayed uninitialized. Same issue also
applies to sr_read_reg.
This can be avoided by checking the return value of sr_share_read_word
and sr_read_reg, and propagating the error if the read operation failed.
Found by code review.

====================
ethtool: rss: small fixes to spec and GET
Two small fixes to the ethtool RSS_GET over Netlink.
Spec is a bit inaccurate and responses miss an identifier.
====================

The response to a GET request in Netlink should fully identify
the queried object. RSS_GET accepts context id as an input,
so it must echo that attribute back to the response.
After (assuming context 1 has been created):
$ ./cli.py --spec netlink/specs/ethtool.yaml \
--do rss-get \
--json '{"header": {"dev-index": 2}, "context": 1}'
{'context': 1,
'header': {'dev-index': 2, 'dev-name': 'eth0'},
[...]

The spec for Ethtool is a bit inaccurate. We don't currently
support dump. Context is only accepted as input and not echoed
to output (which is a separate bug).

In __bnxt_reserve_rings(), the existing code unconditionally sets the
default RSS indirection table to default if netif_is_rxfh_configured()
returns false. This used to be correct before we added RSS contexts
support. For example, if the user is changing the number of ethtool
channels, we will enter this path to reserve the new number of rings.
We will then set the RSS indirection table to default to cover the new
number of rings if netif_is_rxfh_configured() is false.
Now, with RSS contexts support, if the user has added or deleted RSS
contexts, we may now enter this path to reserve the new number of VNICs.
However, netif_is_rxfh_configured() will not return the correct state if
we are still in the middle of set_rxfh(). So the existing code may
set the indirection table of the default RSS context to default by
mistake.
Fix it to check if the reservation of the RX rings is changing. Only
check netif_is_rxfh_configured() if it is changing. RX rings will not
change in the middle of set_rxfh() and this will fix the issue.

Here is the big set of driver core changes for 6.11-rc1.
Lots of stuff in here, with not a huge diffstat, but apis are evolving
which required lots of files to be touched. Highlights of the changes
in here are:
- platform remove callback api final fixups (Uwe took many releases to
get here, finally!)
- Rust bindings for basic firmware apis and initial driver-core
interactions. It's not all that useful for a "write a whole driver
in rust" type of thing, but the firmware bindings do help out the
phy rust drivers, and the driver core bindings give a solid base on
which others can start their work. There is still a long way to go
here before we have a multitude of rust drivers being added, but
it's a great first step.
- driver core const api changes. This reached across all bus types,
and there are some fix-ups for some not-common bus types that
linux-next and 0-day testing shook out. This work is being done to
help make the rust bindings more safe, as well as the C code, moving
toward the end-goal of allowing us to put driver structures into
read-only memory. We aren't there yet, but are getting closer.
- minor devres cleanups and fixes found by code inspection
- arch_topology minor changes
- other minor driver core cleanups
All of these have been in linux-next for a very long time with no
reported problems.
