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 9ffcc372 ("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

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.

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.

error reporting variable.  Also fixed the loop variables that are

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.

Commit 14b41a29 ("net: stmmac: Delete txtimer in suspend") was the
first attempt to fix a race between mod_timer() and setup_timer()
during stmmac_resume(). However the issue still exists as the commit
only addressed half of the issue.

Same race can still happen as stmmac_resume() re-attaches interface
way too early - even before hardware is fully initialized.  Worse,
doing so allows network traffic to restart and stmmac_tx_timer_arm()
being called in the middle of stmmac_resume(), which re-init tx timers
in stmmac_init_coalesce().  timer_list will be corrupted and system
crashes as a result of race between mod_timer() and setup_timer().

Ever since its first commit 0ca7111a ("phy: add AT803x driver") the
PHY ID mask was set to 0xffffffef. It is unclear to me why this mask was
chosen in the first place. Both the AR8031/AR8033 and the AR8035
datasheets mention it is always the given value:
 - for AR8031/AR8033 its 0x004d/0xd074
 - for AR8035 its 0x004d/0xd072

Unfortunately, I don't have a datasheet for the AR8030. Therefore, we
leave its PHY ID mask untouched. For the PHYs mentioned before use the
handy PHY_ID_MATCH_EXACT() macro.
