I forgot to change last_packets field in struct net_rate_estimator.
Without this fix, rate estimators would misbehave after more
than 2^32 packets have been sent.
Another solution would be to be careful and only use the
32 least significant bits of packets counters, but we have
a hole in net_rate_estimator structure and this looks
easier to read/maintain.

====================
100GbE Intel Wired LAN Driver Updates 2019-11-06
This series contains updates to ice driver only.
Scott adds ethtool -m support so that we can read eeprom data on SFP/OSFP
modules.
Anirudh updates the return value to properly reflect when SRIOV is not
supported.
Md Fahad updates the driver to handle a change in the NVM, where the
boot configuration section was moved to the Preserved Field Area (PFA)
of the NVM.
Paul resolves an issue when DCBx requests non-contiguous TCs, transmit
hangs could occur, so configure a default traffic class (TC0) in these
cases to prevent traffic hangs. Adds a print statement to notify the
user when unsupported modules are inserted.
Bruce fixes up the driver unload code flow to ensure we do not clear the
interrupt scheme until the reset is complete, otherwise a hardware error
may occur.
Dave updates the DCB initialization to set is_sw_lldp boolean when the
firmware has been detected to be in an untenable state. This will
ensure that the firmware is in a known state.
Michal saves off the PCI state and I/O BARs address after PCI bus reset
so that after the reset, device registers can be read. Also adds a NULL
pointer check to prevent a potential kernel panic.
Mitch resolves an issue where VF's on PF's other than 0 were not seeing
resets by using the per-PF VF ID instead of the absolute VF ID.
Krzysztof does some code cleanup to remove a unneeded wrapper and
reduces the code complexity.
Brett reduces confusion by changing the name of ice_vc_dis_vf() to
ice_vc_reset_vf() to better describe what the function is actually
doing.
v2: dropped patch 3 "ice: Add support for FW recovery mode detection"
from the origin al series, while Ani makes changes based on
community feedback to implement devlink into the changes.
v3: dropped patch 1 "ice: implement set_eeprom functionality" due to a
bug found and additional changes will be needed when Ani implements
devlink in the driver.

====================
net: phy: at803x device tree binding
Adds a device tree binding to configure the clock and the RGMII voltage.
Changes since v1:
- rebased to latest net-next
- renamed "Atheros" to "Qualcomm Atheros"
- add a new patch to remove config_init() from AR9331
Changes since the RFC:
- renamed the Kconfig entry to "Qualcomm Atheros.." and reordered the
item
- renamed the prefix from atheros to qca
- use the correct name AR803x (instead of AT803x) in new files and
dt-bindings.
- listed the PHY maintainers in the new schema. Hopefully, thats ok.
- fixed a typo in the bindings schema
- run dtb_checks and dt_binding_check and fixed the schema
- dropped the rgmii-io-1v8 property; instead provide two regulators vddh
and vddio, add one consumer vddio-supply
- fix the clock settings for the AR8030/AR8035
- only the AR8031 supports chaning the LDO and the PLL mode in software.
Check if we have the correct PHY.
- new patch to mention the AR8033 which is the same as the AR8031 just
without PTP support
- new patch which corrects any displayed PHY names and comments. Be
consistent.

According to its datasheet, the internal PHY doesn't have debug
registers nor MMDs. Since config_init() only configures delays and
clocks and so on in these registers it won't be needed on this PHY.

When preparing tunnel packets for the link failover or synchronization,
as for the safe algorithm, we added a dummy packet on the pair link but
never sent it out. In the case of failover, the pair link will be reset
anyway. But for link synching, it will always result in retransmission
of the dummy packet after that.
We have also observed that such the retransmission at the early stage
when a new node comes in a large cluster will take some time and hard
to be done, leading to the repeated retransmit failures and the link is
reset.
Since in commit 4929a932be33 ("tipc: optimize link synching mechanism")
we have already built a dummy 'TUNNEL_PROTOCOL' message on the new link
for the synchronization, there's no need for the dummy on the pair one,
this commit will skip it when the new mechanism takes in place. In case
nothing exists in the pair link's transmq, the link synching will just
start and stop shortly on the peer side.
The patch is backward compatible.

When comparing two tun_info, dst_cache member should have been skipped,

Added the following traceroute tests.
IPV6:
Verify that in this scenario
------------------------ N2
| |
------ ------ N3 ----
| R1 | | R2 |------|H2|
------ ------ ----
| |
------------------------ N1
|
----
|H1|
----
where H1's default route goes through R1 and R1's default route goes
through R2 over N2, traceroute6 from H1 to H2 reports R2's address
on N2 and not N1.
IPV4:
Verify that traceroute from H1 to H2 shows 1.0.1.1 in this scenario
1.0.3.1/24
---- 1.0.1.3/24 1.0.1.1/24 ---- 1.0.2.1/24 1.0.2.4/24 ----
|H1|--------------------------|R1|--------------------------|H2|
---- N1 ---- N2 ----
where net.ipv4.icmp_errors_use_inbound_ifaddr is set on R1 and
1.0.3.1/24 and 1.0.1.1/24 are respectively R1's primary and secondary
address on N1.
v2: fixed some typos, and have bridge in R1 instead of R2 in IPV6 test.

ice_vc_dis_vf() tells iavf that it's going to perform a reset
and then performs a software reset. This is misleading based on
the function name because the VF does not get disabled. So fix
this by changing the name to ice_vc_reset_vf().

The VF_MBX_ARQLEN register array is per-PF, not global, so we should not
use the absolute VF ID as an index. Instead, use the per-PF VF ID.
This fixes an issue with VFs on PFs other than 0 not seeing reset.

Adjust ice_init_dcb to set the is_sw_lldp boolean

in an untenable state such that the driver
should forcibly make sure it is off.
This will ensure that the FW is in a known state.

sk->sk_max_ack_backlog can be read without any lock being held
at least in TCP/DCCP cases.
We need to use READ_ONCE()/WRITE_ONCE() to avoid load/store tearing
and/or potential KCSAN warnings.

There are common instances of the following construct :
if (n->confirmed != now)
n->confirmed = now;
A C compiler could legally remove the conditional.
Use READ_ONCE()/WRITE_ONCE() to avoid this problem.
