After commit 4d1a2d9ec1 ("Rename skb to icmp_skb in tcp_v4_err()")
the skb argument has been renamed to icmp_skb only in one function.
I will in a future patch reconciliate these functions to avoid

The commit 8c46fcd783 ("batman-adv: disable ethtool link speed detection
when auto negotiation off") disabled the usage of ethtool's link_ksetting
when auto negotation was enabled due to invalid values when used with
tun/tap virtual net_devices. According to the patch, automatic measurements
should be used for these kind of interfaces.
But there are major flaws with this argumentation:
* automatic measurements are not implemented
* auto negotiation has nothing to do with the validity of the retrieved
values
The first point has to be fixed by a longer patch series. The "validity"
part of the second point must be addressed in the same patch series by
dropping the usage of ethtool's link_ksetting (thus always doing automatic
measurements over ethernet).
Drop the patch again to have more default values for various net_device
types/configurations. The user can still overwrite them using the
batadv_hardif's BATADV_ATTR_THROUGHPUT_OVERRIDE.

The issue was reported by syzbot. When the function br_mrp_parse was
called with a valid net_bridge_port, the net_bridge was an invalid
pointer. Therefore the check br->stp_enabled could pass/fail
depending where it was pointing in memory.
The fix consists of setting the net_bridge pointer if the port is a
valid pointer.

The traffic class (TC) attribute of packet traps determines through which
TC a packet trap will be scheduled through the CPU port.
The priority attribute determines which trap will be triggered in case
several packet traps match a packet.
We try to configure these attributes to the same value for all packet
traps as there is little reason not to.
Some packet traps did not use the same value, so rectify that now.

As explained in commit 9ffcc3725f ("mlxsw: spectrum: Allow packets to
be trapped from any PG"), incoming packets can be admitted to the shared
buffer and forwarded / trapped, if:
(Ingress{Port}.Usage < Thres && Ingress{Port,PG}.Usage < Thres &&
Egress{Port}.Usage < Thres && Egress{Port,TC}.Usage < Thres)
||
(Ingress{Port}.Usage < Min || Ingress{Port,PG} < Min ||
Egress{Port}.Usage < Min || Egress{Port,TC}.Usage < Min)
Trapped packets are scheduled to transmission through the CPU port.
Currently, the minimum and maximum quotas of traffic class (TC) 0 of the
CPU port are 0, which means it is not usable.
Assign non-zero quotas to TC 0 of the CPU port, so that it could be
utilized by subsequent patches.

Currently, IPv4 DHCP packets are trapped during L2 forwarding, which
means that packets might be trapped unnecessarily. Instead, only trap
the DHCP packets that reach the router. Either because they were flooded
to the router port or forwarded to it by the FDB. This is consistent

Pull scheduler fixes from Thomas Gleixner:
"A set of fixes for the scheduler:
- Fix handling of throttled parents in enqueue_task_fair() completely.
The recent fix overlooked a corner case where the first iteration
terminates due to an entity already being on the runqueue which
makes the list management incomplete and later triggers the
assertion which checks for completeness.
- Fix a similar problem in unthrottle_cfs_rq().
- Show the correct uclamp values in procfs which prints the effective
value twice instead of requested and effective"

get_coalesce returns 0 or ERRNO, but the return value isn't checked.
The returned coalesce data may be invalid if an ERRNO is set,
therefore better check and propagate the return value.

net: provide a devres variant of register_netdev()
Using devres helpers allows to shrink the probing code, avoid memory leaks in
error paths make sure the order in which resources are freed is the exact
opposite of their allocation. This series proposes to add a devres variant
of register_netdev() that will only work with net_device structures whose
memory is also managed.
First we add the missing documentation entry for the only other networking
devres helper: devm_alloc_etherdev().
Next we move devm_alloc_etherdev() into a separate source file.
We then use a proxy structure in devm_alloc_etherdev() to improve readability.
Last: we implement devm_register_netdev() and use it in mtk-eth-mac driver.
v1 -> v2:
- rebase on top of net-next after driver rename, no functional changes

Not using a proxy structure to store struct net_device doesn't save
anything in terms of compiled code size or memory usage but significantly
decreases the readability of the code with all the pointer casting.
Define struct net_device_devres and use it in devm_alloc_etherdev_mqs().

There's currently only a single devres helper in net/ - devm variant
of alloc_etherdev. Let's move it to net/devres.c with the intention of
assing a second one: devm_register_netdev(). This new routine will need
to know the address of the release function of devm_alloc_etherdev() so
that it can verify (using devres_find()) that the struct net_device
that's being passed to it is also resource managed.

rtl_eri_read() returns the full 32bit value, therefore there's no
benefit in writing back parts of it only. handle it like the vendor
driver and write the full 32 bit always. Omitting the mask argument
avoids some overhead and makes the code better readable.

100GbE Intel Wired LAN Driver Updates 2020-05-22
This series contains updates to virtchnl and the ice driver.
Geert Uytterhoeven fixes a data structure alignment issue in the
virtchnl structures.
Henry adds Flow Director support which allows for the redirection on
ntuple rules over six patches. Initially Henry adds the initial
infrastructure for Flow Director, and then later adds IPv4 and IPv6
support, as well as being able to display the ntuple rules.
Bret add Accelerated Receive Flow Steering (aRFS) support which is used
to steer receive flows to a specific queue. Fixes a transmit timeout
when the VF link transitions from up/down/up because the transmit and
receive queue interrupts are not enabled as part of VF's link up. Fixed
an issue when the default VF LAN address is changed and after reset the
PF will attempt to add the new MAC, which fails because it already
exists. This causes the VF to be disabled completely until it is removed
and enabled via sysfs.
Anirudh (Ani) makes a fix where the ice driver needs to call set_mac_cfg
to enable jumbo frames, so ensure it gets called during initialization
and after reset. Fix bad register reads during a register dump in
ethtool by removing the bad registers.
Paul fixes an issue where the receive Malicious Driver Detection (MDD)
auto reset message was not being logged because it occurred after the VF
reset.
Victor adds a check for compatibility between the Dynamic Device
Personalization (DDP) package and the NIC firmware to ensure that
everything aligns.
Jesse fixes a administrative queue string call with the appropriate
error reporting variable. Also fixed the loop variables that are
comparing or assigning signed against unsigned values.

1GbE Intel Wired LAN Driver Updates 2020-05-22
This series contains updates to e1000e, igc and igb.
Many of the patches in this series are fixes, but many of the igc fixes
are based on the recent filter rule handling Andre has been working,
which will not backport to earlier/stable kernels. The remaining fixes
for e1000e and igb have CC'd stable where applicable.
Andre continue with his refactoring of the filter rule code to help with
reducing the complexity, in multiple patches. Fix the inconsistent size
of a struct field. Fixed an issue where filter rules stay active in the
hardware, even after it was deleted, so make sure to disable the filter
rule before deleting. Fixed an issue with NFC rules which were dropping
valid multicast MAC address. Fixed how the NFC rules are restored after
the NIC is reset or brought up, so that they are restored in the same order
they were initially setup in. Fix a potential memory leak when the
driver is unloaded and the NFC rules are not flushed from memory
properly. Fixed how NFC rule validation handles when a request to
overwrite an existing rule. Changed the locking around the NFC rule API
calls from spin_locks to mutex locks to avoid unnecessary busy waiting
on lock contention.
Sasha clean up more unused code in the igc driver.
Kai-Heng Feng from Canonical provides three fixes, first has igb report
the speed and duplex as unknown when in runtime suspend. Fixed e1000e
to pass up the error when disabling ULP mode. Fixed e1000e performance
by disabling TSO by default for certain MACs.
Vitaly disables S0ix entry and exit flows for ME systems.

This series includes two updates and one cleanup patch
1) Tang Bim, clean-up with IS_ERR() usage
2) Vlad introduces a new mlx5 kconfig flag for TC support
This is required due to the high volume of current and upcoming
development in the eswitch and representors areas where some of the
feature are TC based such as the downstream patches of MPLSoUDP and
the following representor bonding support for VF live migration and
uplink representor dynamic loading.
For this Vlad kept TC specific code in tc.c and rep/tc.c and
organized non TC code in representors specific files.
3) Eli Cohen adds support for MPLS over UPD encap and decap TC offloads.
