cabf06e5a2 Merge tag 'wireless-drivers-next-2020-08-04' of git://git.kernel.org/pub/scm/linux/kernel/git/kvalo/wireless-drivers-next
Kalle Valo says:

====================
wireless-drivers-next patches for v5.9

Second set of patches for v5.9. mt76 has most of patches this time.
Otherwise it's just smaller fixes and cleanups to other drivers.

There was a major conflict in mt76 driver between wireless-drivers and
wireless-drivers-next. I solved that by merging the former to the
latter.

Major changes:

rtw88

* add support for ieee80211_ops::change_interface

* add support for enabling and disabling beacon

* add debugfs file for testing h2c

mt76

* ARP filter offload for 7663

* runtime power management for 7663

* testmode support for mfg calibration

* support for more channels

====================
mlx5-updates-2020-08-03

This patchset introduces some updates to mlx5 driver.

1) Jakub converts mlx5 to use the new udp tunnel infrastructure.
   Starting with a hack to allow drivers to request a static configuration
   of the default vxlan port, and then a patch that converts mlx5.

2) Parav implements change_carrier ndo for VF eswitch representors,
   to speedup link state control of representors netdevices.

3) Alex Vesker, makes a simple update to software steering to fix an issue
   with push vlan action sequence

4) Leon removes a redundant dump stack on error flow.

966e505976 udp_tunnel: add the ability to hard-code IANA VXLAN
mlx5 has the IANA VXLAN port (4789) hard coded by the device,
instead of being added dynamically when tunnels are created.

To support this add a workaround flag to struct udp_tunnel_nic_info.
Skipping updates for the port is fairly trivial, dumping the hard
coded port via ethtool requires some code duplication. The port
is not a part of any real table, we dump it in a special table
which has no tunnel types supported and only one entry.

This is the last known workaround / hack needed to convert
all drivers to the new infra.

ec4f5b3617 mlxsw: spectrum: Use different trap group for externally routed packets
Cited commit mistakenly removed the trap group for externally routed
packets (e.g., via the management interface) and grouped locally routed
and externally routed packet traps under the same group, thereby
subjecting them to the same policer.

This can result in problems, for example, when FRR is restarted and
suddenly all transient traffic is trapped to the CPU because of a
default route through the management interface. Locally routed packets
required to re-establish a BGP connection will never reach the CPU and
the routing tables will not be re-populated.

Fix this by using a different trap group for externally routed packets.

a57066b1a0 Merge git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net
The UDP reuseport conflict was a little bit tricky.

The net-next code, via bpf-next, extracted the reuseport handling
into a helper so that the BPF sk lookup code could invoke it.

At the same time, the logic for reuseport handling of unconnected
sockets changed via commit efc6b6f6c3
which changed the logic to carry on the reuseport result into the
rest of the lookup loop if we do not return immediately.

This requires moving the reuseport_has_conns() logic into the callers.

While we are here, get rid of inline directives as they do not belong
in foo.c files.

The other changes were cases of more straightforward overlapping
modifications.

749c08f820 net: dccp: Add SIOCOUTQ IOCTL support (send buffer fill)
This adds support for the SIOCOUTQ IOCTL to get the send buffer fill
of a DCCP socket, like UDP and TCP sockets already have.

Regarding the used data field: DCCP uses per packet sequence numbers,
not per byte, so sequence numbers can't be used like in TCP. sk_wmem_queued
is not used by DCCP and always 0, even in test on highly congested paths.
Therefore this uses sk_wmem_alloc like in UDP.

4787dd582d bareudp: Reverted support to enable & disable rx metadata collection
The commit fe80536acf ("bareudp: Added attribute to enable & disable
rx metadata collection") breaks the the original(5.7) default behavior of
bareudp module to collect RX metadadata at the receive. It was added to
avoid the crash at the kernel neighbour subsytem when packet with metadata
from bareudp is processed. But it is no more needed as the
commit 394de110a7 ("net: Added pointer check for
dst->ops->neigh_lookup in dst_neigh_lookup_skb") solves this crash.

The concept of timestamping DSA switches / Ethernet PHYs is becoming
more and more popular, however the Linux kernel timestamping code has
evolved quite organically and there's layers upon layers of new and old
code that need to work together for things to behave as expected.

Add this chapter to explain what the overall goals are.

c7d759eb7b ethtool: add tunnel info interface
Add an interface to report offloaded UDP ports via ethtool netlink.

Now that core takes care of tracking which UDP tunnel ports the NICs
are aware of we can quite easily export this information out to
user space.

The responsibility of writing the netlink dumps is split between
ethtool code and udp_tunnel_nic.c - since udp_tunnel module may
not always be loaded, yet we should always report the capabilities
of the NIC.

$ ethtool --show-tunnels eth0
Tunnel information for eth0:
  UDP port table 0:
    Size: 4
    Types: vxlan
    No entries
  UDP port table 1:
    Size: 4
    Types: geneve, vxlan-gpe
    Entries (1):
        port 1230, vxlan-gpe

v4:
 - back to v2, build fix is now directly in udp_tunnel.h
v3:
 - don't compile ETHTOOL_MSG_TUNNEL_INFO_GET in if CONFIG_INET
   not set.
v2:
 - fix string set count,
 - reorder enums in the uAPI,
 - fix type of ETHTOOL_A_TUNNEL_UDP_TABLE_TYPES to bitset
   in docs and comments.
