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.

For tcindex filter, it is too late to initialize the
net pointer in tcf_exts_validate(), as tcf_exts_get_net()
requires a non-NULL net pointer. We can just move its
initialization into tcf_exts_init(), which just requires
an additional parameter.
This makes the code in tcindex_alloc_perfect_hash()
prettier.

Kalle Valo says:
====================
wireless-drivers-next patches for 5.1
Most likely the last set of patches for 5.1. WPA3 support to ath10k
and qtnfmac. FTM support to iwlwifi and ath10k. And of course other
new features and bugfixes.
wireless-drivers was merged due to dependency in mt76.
Major changes:
iwlwifi
* HE radiotap
* FTM (Fine Timing Measurement) initiator and responder implementation
* bump supported firmware API to 46
* VHT extended NSS support
* new PCI IDs for 9260 and 22000 series
ath10k
* change QMI interface to support the new (and backwards incompatible)
interface from HL3.1 and used in recent HL2.0 branch firmware
releases
* support WPA3 with WCN3990
* support for mac80211 airtime fairness based on transmit rate
estimation, the firmware needs to support WMI_SERVICE_PEER_STATS to
enable this
* report transmit airtime to mac80211 with firmwares having
WMI_SERVICE_REPORT_AIRTIME feature, this to have more accurate
airtime fairness based on real transmit time (instead of just
estimated from transmit rate)
* support Fine Timing Measurement (FTM) responder role
* add dynamic VLAN support with firmware having WMI_SERVICE_PER_PACKET_SW_ENCRYPT
* switch to use SPDX license identifiers
ath
* add new country codes for US
brcmfmac
* support monitor frames with the hardware/ucode header
qtnfmac
* enable WPA3 SAE and OWE support
mt76
* beacon support for USB devices (mesh+ad-hoc only)
rtlwifi
* convert to use SPDX license identifiers
libertas_tf
* get the MAC address before registering the device

This extends the NL80211_CMD_ASSOCIATE event case to report
NL80211_ATTR_REQ_IE similarly to what is already done with the
NL80211_CMD_CONNECT events if the driver provides this information. In
practice, this adds (Re)Association Request frame information element
reporting to mac80211 drivers for the cases where user space SME is
used.
This provides more information for user space to figure out which
capabilities were negotiated for the association. For example, this can
be used to determine whether HT, VHT, or HE is used.

clang warns about overflowing the data[] member in the struct pnpipehdr:

Using a flexible array member at the end of the struct avoids the
warning, but since we cannot have a flexible array member inside
of the union, each index now has to be moved back by one, which
makes it a little uglier.

In preparation for removing switchdev_port_attr_get(), introduce
PORT_PRE_BRIDGE_FLAGS which will be called through
switchdev_port_attr_set(), in the caller's context (possibly atomic) and
which must be checked by the switchdev driver in order to return whether
the operation is supported or not.
This is entirely analoguous to how the BRIDGE_FLAGS_SUPPORT works,
except it goes through a set() instead of get().

Add devlink flash update command. Advanced NICs have firmware
stored in flash and often cryptographically secured. Updating
that flash is handled by management firmware. Ethtool has a
flash update command which served us well, however, it has two
shortcomings:
- it takes rtnl_lock unnecessarily - really flash update has
nothing to do with networking, so using a networking device
as a handle is suboptimal, which leads us to the second one:
- it requires a functioning netdev - in case device enters an
error state and can't spawn a netdev (e.g. communication
with the device fails) there is no netdev to use as a handle
for flashing.
Devlink already has the ability to report the firmware versions,
now with the ability to update the firmware/flash we will be
able to recover devices in bad state.
To enable updates of sub-components of the FW allow passing
component name. This name should correspond to one of the
versions reported in devlink info.
v1: - replace target id with component name (Jiri).

The netfilter conflicts were rather simple overlapping
changes.
However, the cls_tcindex.c stuff was a bit more complex.
On the 'net' side, Cong is fixing several races and memory
leaks. Whilst on the 'net-next' side we have Vlad adding
the rtnl-ness support.
What I've decided to do, in order to resolve this, is revert the
conversion over to using a workqueue that Cong did, bringing us back
to pure RCU. I did it this way because I believe that either Cong's
races don't apply with have Vlad did things, or Cong will have to
implement the race fix slightly differently.

With the introduction of flow_stats_update(), drivers now update the stats
fields of the passed tc_cls_flower_offload struct, rather than call
tcf_exts_stats_update() directly to update the stats of offloaded TC
flower rules. However, if multiple qdiscs are registered to a TC shared
block and a flower rule is applied, then, when getting stats for the rule,
multiple callbacks may be made.
Take this into consideration by modifying flow_stats_update to gather the
stats from all callbacks. Currently, the values in tc_cls_flower_offload
only account for the last stats callback in the list.

Implement BPF_LWT_ENCAP_IP mode in bpf_lwt_push_encap BPF helper.
It enables BPF programs (specifically, BPF_PROG_TYPE_LWT_IN and
BPF_PROG_TYPE_LWT_XMIT prog types) to add IP encapsulation headers
to packets (e.g. IP/GRE, GUE, IPIP).
This is useful when thousands of different short-lived flows should be
encapped, each with different and dynamically determined destination.
Although lwtunnels can be used in some of these scenarios, the ability
to dynamically generate encap headers adds more flexibility, e.g.
when routing depends on the state of the host (reflected in global bpf
maps).
v7 changes:
- added a call skb_clear_hash();
- removed calls to skb_set_transport_header();
- refuse to encap GSO-enabled packets.
v8 changes:
- fix build errors when LWT is not enabled.
Note: the next patch in the patchset with deal with GSO-enabled packets,
which are currently rejected at encapping attempt.

Some protocols have other means to verify the payload integrity
(AH, ESP, SCTP) while others are incompatible with nf_ip(6)_checksum
implementation because checksum is either optional or might be
partial (UDPLITE, DCCP, GRE). Because nf_ip(6)_checksum was used
to validate the packets, ip(6)tables REJECT rules were not capable
to generate ICMP(v6) errors for the protocols mentioned above.

for IPv4 packets that carry other transport protocols than TCP or
UDP (pseudo-header used protocol 0 iso the proper value).

Currently, tcf_block doesn't use any synchronization mechanisms to protect
critical sections that manage lifetime of its chains. block->chain_list and
multiple variables in tcf_chain that control its lifetime assume external
synchronization provided by global rtnl lock. Converting chain reference
counting to atomic reference counters is not possible because cls API uses
multiple counters and flags to control chain lifetime, so all of them must
be synchronized in chain get/put code.
Use single per-block lock to protect block data and manage lifetime of all
chains on the block. Always take block->lock when accessing chain_list.
Chain get and put modify chain lifetime-management data and parent block's
chain_list, so take the lock in these functions. Verify block->lock state
with assertions in functions that expect to be called with the lock taken
and are called from multiple places. Take block->lock when accessing
filter_chain_list.
In order to allow parallel update of rules on single block, move all calls
to classifiers outside of critical sections protected by new block->lock.
Rearrange chain get and put functions code to only access protected chain
data while holding block lock:
- Rearrange code to only access chain reference counter and chain action
reference counter while holding block lock.
- Extract code that requires block->lock from tcf_chain_destroy() into
standalone tcf_chain_destroy() function that is called by
__tcf_chain_put() in same critical section that changes chain reference
counters.

Modify the kernel users of the TCA_ACT_* macros to use TCA_ID_*. For
example, use TCA_ID_GACT instead of TCA_ACT_GACT. This will align with
TCA_ID_POLICE and also differentiates these identifier, used in struct
tc_action_ops type field, from other macros starting with TCA_ACT_.
To make things clearer, we name the enum defining the TCA_ID_*
identifiers and also change the "type" field of struct tc_action to
id.

According to the algorithm described in the comment block at the
beginning of ip_rt_send_redirect, the host should try to send
'ip_rt_redirect_number' ICMP redirect packets with an exponential
backoff and then stop sending them at all assuming that the destination
ignores redirects.
If the device has previously sent some ICMP error packets that are
rate-limited (e.g TTL expired) and continues to receive traffic,
the redirect packets will never be transmitted. This happens since
peer->rate_tokens will be typically greater than 'ip_rt_redirect_number'
and so it will never be reset even if the redirect silence timeout
(ip_rt_redirect_silence) has elapsed without receiving any packet
requiring redirects.
Fix it by using a dedicated counter for the number of ICMP redirect
packets that has been sent by the host
I have not been able to identify a given commit that introduced the
issue since ip_rt_send_redirect implements the same rate-limiting
algorithm from commit 1da177e4c3f4 ("Linux-2.6.12-rc2")

Currently, user can do dump or get of param values right after the
devlink params are registered. However the driver may not be initialized
which is an issue. The same problem happens during notification
upon param registration. Allow driver to publish devlink params
whenever it is ready to handle get() ops. Note that this cannot
be resolved by init reordering, as the "driverinit" params have
to be available before the driver is initialized (it needs the param
values there).

An ipvlan bug fix in 'net' conflicted with the abstraction away
of the IPV6 specific support in 'net-next'.
Similarly, a bug fix for mlx5 in 'net' conflicted with the flow
action conversion in 'net-next'.
