Neigh entry has reference counter, however it is only used when scheduling

reference counter reaches zero. This can result spurious neigh update
events, when there is an event on entry that has zero encaps attached.
However, such events are rare and properly handled by neigh update handler.
Extend encap entry with reference to neigh hash entry in order to be able
to directly release it when encap is detached, instead of lookup nhe by key

mac80211: minstrel_ht: improve rate probing for devices with static fallback
On some devices that only support static rate fallback tables sending rate
control probing packets can be really expensive.
Probing lower rates can already hurt throughput quite a bit. What hurts even
more is the fact that on mt76x0/mt76x2, single probing packets can only be
forced by directing packets at a different internal hardware queue, which
causes some heavy reordering and extra latency.
The reordering issue is mainly problematic while pushing lots of packets to
a particular station. If there is little activity, the overhead of probing is
neglegible.
The static fallback behavior is designed to pretty much only handle rate
control algorithms that use only a very limited set of rates on which the
algorithm switches up/down based on packet error rate.
In order to better support that kind of hardware, this patch implements a
different approach to rate probing where it switches to a slightly higher rate,
waits for tx status feedback, then updates the stats and switches back to
the new max throughput rate. This only triggers above a packet rate of 100
per stats interval (~50ms).
For that kind of probing, the code has to reduce the set of probing rates
a lot more compared to single packet probing, so it uses only one packet
per MCS group which is either slightly faster, or as close as possible to
the max throughput rate.
This allows switching between similar rates with different numbers of
streams. The algorithm assumes that the hardware will work its way lower
within an MCS group in case of retransmissions, so that lower rates don't
have to be probed by the high packets per second rate probing code.
To further reduce the search space, it also does not probe rates with lower
channel bandwidth than the max throughput rate.
At the moment, these changes will only affect mt76x0/mt76x2.

mlx5 RX reporter: reports and recovers from timeouts and RX completion
error.
1) Perform TX reporter cleanup. In order to maintain the
code flow as similar as possible between RX and TX reporters, start the
set with cleanup.
2) Prepare for code sharing, generalize and move shared
functionality.
3) Refactor and extend TX reporter diagnostics information
to align the TX reporter diagnostics output with the RX reporter's
diagnostics output.
4) Add helper functions Patch 11: Add RX reporter, initially
supports only the diagnostics call back.
5) Change ICOSQ (Internal Operations Send Queue) open/close flow to
avoid race between interface down and completion error recovery.
6) Introduce recovery flows for RX ring population timeout on ICOSQ,
and for completion errors on ICOSQ and on RQ (Regular receive queues).
7) Include RX reporters in mlx5 documentation.

100GbE Intel Wired LAN Driver Updates 2019-08-20
This series contains updates to ice driver only.
Brett fixes the detection of a hung transmit ring by checking the
software based tail (next_to_use) to determine if there is pending work.
Updates the driver to assume that using more than one receive queue per
receive ring container is a rare case, so use unlikely() in the case
were we actually need to divide our budget for multiple queues. Fixed
an issue where the write back on ITR bit was not being set when
interrupts are disabled, which was causing only write backs when polling
only when a cache line is filled. Cleans up unnecessary wait times
during VF bring up and reset paths. Increased the mailbox size for
receive queues that are used to communicate with VFs to accommodate the
large number of VFs that the driver can support.
Akeem restructures the initialization flows for VFs, including how VFs
are configured and resources allocated to improve flows so that when we
clean up resources, we do not try to free resources that were never
allocated. Organizes code to ensure that VF specific code is located in
the SR-IOV specific file.
Paul fixes an issue when setting the pause parameter which was
incorrectly blocking users from changing receive or transmit pause
settings. Ensure register access for MSIX vector index is only done in
the PF space and not absolute device space.
Usha fixes a potential kernel hang in the DCB rebuild path when in CEE
mode, where the ETS recommended DCB configuration is not being set or
set correctly.
Mitch updates the driver to process all receive descriptors, regardless
of the size of the associated data.
Tony fixes and issue during the reset/rebuild path of a PF VSI where we
were assuming that the PF VSI was always to be enabled, which can
attempt to bring up a PF VSI on a downed interface which can lead to
various crashes.
Pawel fixes up variable definitions to match the type of data being
stored.
v2: Dropped patch 1 of the series to add ethtool support to query/add
channels on a VSI, while we re-qork the functionality to match the
ethtool expected behavior to report combined (Tx and Rx) numbers.

ice: Increase size of Mailbox receive queue for many VFs
Currently we use the ICE_MBXQ_LEN for both the Mailbox send and receive
queues that are used to communicate with VFs. This is fine for the send
queue because the PF driver will lock the queue for every single send,
but for the Mailbox receive queue every VF is posting to its Mailbox
send queue and the hardware is then handing the message to the PF on its
Mailbox receive queue. This becomes a problem with many VFs because it
seems to overburden the Mailbox receive queue on the PF. Fix this by
increasing the Mailbox receive queue for the PF to 512 entries.
The number 512 was determined based on the number of VFs supported by
the device. We can have a total of 256 VFs so in the worst case this
allows the VFs to put 2 messages in the PFs Mailbox receive queue at the
same time.

s390/qeth: use correct length field in SNMP cmd callback
qeth_snmp_command_cb() is the only cmd callback that pulls the reply's
data length from a low-level transport header field. This requires
additional complexity (ie. reply->offset) to make the header accessible
to what is supposed to be a pure IPA cmd callback.
Adapter cmds have a length field in their sub-cmd header, get the data
length from there instead.

s390/qeth: propagate length of processed cmd IO data to callback
When an cmd IO completes in qeth_irq(), calculate how much data was
processed by the device and pass this value to the cmd's callback.
This allows cmds that retrieve data from the device to check whether
sufficient data was received, so we do that in qeth_read_conf_data_cb().

net/mlx5: Fix the order of fc_stats cleanup
Previously, mlx5_cleanup_fc_stats() would cleanup the flow counter
pool beofre releasing all the counters to it, which would result in
flow counter bulks not getting freed. Resolve this by changing the
order in which elements of fc_stats are cleaned up, so that the flow

net/mlx5e: Fix deallocation of non-fully init encap entries
Recent rtnl lock dependency refactoring changed encap entry attach code to
insert encap entry to hash table before it was fully initialized in order
to allow concurrent tc users to wait on completion for encap entry to
finish initialization. That change required all the users of encap entry to
obtain reference to it first and for caller that creates encap to put

However, releasing reference to such encap entry that wasn't fully

Merge branch 'net-dsa-enable-and-disable-all-ports'
Vivien Didelot says:
====================
net: dsa: enable and disable all ports
The DSA stack currently calls the .port_enable and .port_disable switch
callbacks for slave ports only. However, it is useful to call them for all
port types. For example this allows some drivers to delay the optimization
of power consumption after the switch is setup. This can also help reducing
the setup code of drivers a bit.
The first DSA core patches enable and disable all ports of a switch, regardless
their type. The last mv88e6xxx patches remove redundant code from the driver
setup and the said callbacks, now that they handle SERDES power for all ports.
Changes in v2: do not guard .port_disable for broadcom switches.

SERDES is powered on for CPU and DSA ports and powered down for unused
ports at setup time. But now that DSA calls mv88e6xxx_port_enable
and mv88e6xxx_port_disable for all ports, the SERDES power can now
be handled after setup inconditionally for all ports.
Using the port enable and disable callbacks also have the benefit to
handle the SERDES IRQ for non user ports as well.

The .port_enable and .port_disable operations are currently only
called for user ports, hence assuming they have a slave device. In
preparation for using these operations for other port types as well,
simply guard all implementations against non user ports and return
directly in such case.
Note that bcm_sf2_sw_suspend() currently calls bcm_sf2_port_disable()
(and thus b53_disable_port()) against the user and CPU ports, so do
not guards those functions. They will be called for unused ports in
the future, but that was expected by those drivers anyway.

It is currently difficult to read the different steps involved in the

ice: Restructure VFs initialization flows
This patch restructures how VFs are configured, and resources allocated.
Instead of freeing resources that were never allocated, and resetting
empty VFs that have never been created - the new flow will just allocate
resources for number of requested VFs based on the availability.
During VFs initialization process, global interrupt is disabled, and
rearmed after getting MSIX vectors for VFs. This allows immediate mailbox
communications, instead of delaying it till later and VFs.
PF communications resulted to using polling instead of actual interrupt.
The issue manifested when creating higher number of VFs (128 VFs) per PF.
