Three conflicts, one of which, for marvell10g.c is non-trivial and
requires some follow-up from Heiner or someone else.
The issue is that Heiner converted the marvell10g driver over to
use the generic c45 code as much as possible.
However, in 'net' a bug fix appeared which makes sure that a new
local mask (MDIO_AN_10GBT_CTRL_ADV_NBT_MASK) with value 0x01e0
is cleared.

This fixes a regression introduced by
commit 0d2e778e38e0ddffab4bb2b0e9ed2ad5165c4bf7
"net: phy: replace PHY_HAS_INTERRUPT with a check for
config_intr and ack_interrupt".
This assumes that a PHY cannot trigger interrupt unless
it has .config_intr() or .ack_interrupt() implemented.
A later patch makes the code assume both need to be
implemented for interrupts to be present.
But this PHY (which is inside a DSA) will happily
fire interrupts without either callback.
Implement dummy callbacks for .config_intr() and
.ack_interrupt() in the phy header to fix this.
Tested on the RTL8366RB on D-Link DIR-685.
Fixes: 0d2e778e38e0 ("net: phy: replace PHY_HAS_INTERRUPT with a check for config_intr and ack_interrupt")

syzbot was able to trigger another soft lockup [1]
I first thought it was the O(N^2) issue I mentioned in my
prior fix (f657d22ee1f "net/x25: do not hold the cpu
too long in x25_new_lci()"), but I eventually found
that x25_bind() was not checking SOCK_ZAPPED state under
socket lock protection.
This means that multiple threads can end up calling
x25_insert_socket() for the same socket, and corrupt x25_list

This reverts commit 5a2de63fd1a5 ("bridge: do not add port to router list
when receives query with source 0.0.0.0") and commit 0fe5119e267f ("net:
bridge: remove ipv6 zero address check in mcast queries")
The reason is RFC 4541 is not a standard but suggestive. Currently we
will elect 0.0.0.0 as Querier if there is no ip address configured on
bridge. If we do not add the port which recives query with source
0.0.0.0 to router list, the IGMP reports will not be about to forward
to Querier, IGMP data will also not be able to forward to dest.
As Nikolay suggested, revert this change first and add a boolopt api
to disable none-zero election in future if needed.

Just like commit e2ba732a1681 ("selftests: fib_tests: sleep after
changing carrier"), wait one second to allow linkwatch to propagate the
carrier change to the stack.
There are two sets of carrier tests. The first slept after the carrier
was set to off, and when the second set ran, it was likely that the
linkwatch would be able to run again without much delay, reducing the
likelihood of a race. However, if you run 'fib_tests.sh -t carrier' on a
loop, you will quickly notice the failures.
Sleeping on the second set of tests make the failures go away.

Because 1000BaseT isn't covered by Clause 45, the 1000BaseT flags in
phydev->lp_advertising may have been set based on vendor registers
already. genphy_c45_read_lpa() would clear these flags as of today.
Therefore switch to mii_lpa_mod_linkmode_lpa_t.

AQCS109 belongs to a family of PHY's where certain members don't

reports 10G and 5G capability. Therefore remove the not supported
modes for AQCS109.

mlxsw: Add support for new port types and speeds for Spectrum-2
Shalom says:
This patchset adds support for new port types and speeds for Spectrum-2.
Patch #1 + #2 removes an unsupported PTYS field and a duplicate link
mode entry.
Patch #3 queries port's connector type from firmware instead of deriving
it from port admin state.
Patch #4 renames functions which relate to port type-speed to be
Spectrum-1 specific.
Patch #5 defines port type-speed operations and applies it for
Spectrum-1.
Patch #6 + #7 are small renaming and cosmetic changes.
Patch #8 adds new port type-speed fields for PTYS register. These new
fields extend the existing ones in order to support more types and
speeds.
Patch #9 adds Spectrum-2 support for port type-speed operations.
Patch #10 adds Spectrum-2 new port types and speeds.
For Spectrum-2, the user must configure all the types per speed if he /
she wants a specific speed to be advertised. For example, if the user
wants to advertise 100Gbps 4-lanes speed, the following ethtool bits
should be advertised:
Supported ethtool bits for 100Gbps 4-lanes:
0x1000000000 100000baseKR4 Full
0x2000000000 100000baseSR4 Full
0x4000000000 100000baseCR4 Full
0x8000000000 100000baseLR4_ER4 Full

Add Spectrum-2 ASIC port type-speed operations.
Since multiple ethtool link modes are represented using a single bit in the
ASIC, the driver forces the user to configure all types per a specific
speed. For example, if the user wants to advertise 100Gbps 4-lanes speed,
he should advertise all the types of 100Gbps 4-lanes speed that are
supported by the ASIC as shown below:
Supported ethtool bits for 100Gbps 4-lanes:
0x1000000000 100000baseKR4 Full

for BPF related discussions, originally in context of BPF track at LSF/MM
for topic discussions. It's *optional* but *desirable* to keep it in Cc for
BPF related kernel/loader/llvm/tooling threads, meaning also infrastructure
like llvm that sits on top of kernel but is crucial to BPF. In any case,
netdev with it's bpf delegate is *as-is* today primary list for patches, so
nothing changes in the workflow. Main purpose is to have some more awareness
