====================
wireless-drivers-next patches for v5.7Second set of patches for v5.7. Lots of cleanup patches this time, but
of course various new features as well fixes.When merging with wireless-drivers this pull request has a conflict in:
drivers/net/wireless/intel/iwlwifi/pcie/drv.c
To solve that just drop the changes from commit cf52c8a776d1 in
wireless-drivers and take the hunk from wireless-drivers-next as is.
The list of specific subsystem device IDs are not necessary after
commit d6f2134a3831 (in wireless-drivers-next) anymore, the detection
is based on other characteristics of the devices.Major changes:
qtnfmac
* support WPA3 SAE and OWE in AP mode
ath10k
* support for getting btcoex settings from Device Tree
* support QCA9377 SDIO device
ath11k
* add HE rate accounting
* add thermal sensor and cooling devices
mt76
* MT7663 support for the MT7615 driver

The SJA1105 switch family has a PTP_CLK pin which emits a signal with
fixed 50% duty cycle, but variable frequency and programmable start time.On the second generation (P/Q/R/S) switches, this pin supports even more
functionality. The use case described by the hardware documents talks
about synchronization via oneshot pulses: given 2 sja1105 switches,
arbitrarily designated as a master and a slave, the master emits a
single pulse on PTP_CLK, while the slave is configured to timestamp this
pulse received on its PTP_CLK pin (which must obviously be configured as
input). The difference between the timestamps then exactly becomes the
slave offset to the master.The only trouble with the above is that the hardware is very much tied
into this use case only, and not very generic beyond that:
- When emitting a oneshot pulse, instead of being told when to emit it,
the switch just does it "now" and tells you later what time it was,
via the PTPSYNCTS register. [ Incidentally, this is the same register
that the slave uses to collect the ext_ts timestamp from, too. ]
- On the sync slave, there is no interrupt mechanism on reception of a
new extts, and no FIFO to buffer them, because in the foreseen use
case, software is in control of both the master and the slave pins,
so it "knows" when there's something to collect.These 2 problems mean that:
- We don't support (at least yet) the quirky oneshot mode exposed by
the hardware, just normal periodic output.
- We abuse the hardware a little bit when we expose generic extts.
Because there's no interrupt mechanism, we need to poll at double the
frequency we expect to receive a pulse. Currently that means a
non-configurable "twice a second".Signed-off-by: Vladimir Oltean

The AVB table contains the CAS_MASTER field (to be added in the next
patch) which decides the direction of the PTP_CLK pin.Reconfiguring this field dynamically is highly preferable to having to
reset the switch and upload a new static configuration, so we add
support for exactly that.Signed-off-by: Vladimir Oltean

Because the PTP_CLK pin starts toggling only at a time higher than the
current PTP clock, this helper from the time-aware shaper code comes in
handy here as well. We'll use it to transform generic user input for the
perout request into valid input for the sja1105 hardware.Signed-off-by: Vladimir Oltean

These fields configure the destination and source MAC address that the
switch will put in the Ethernet frames sent towards the CPU port that
contain RX timestamps for PTP.These fields do not enable the feature itself, that is configured via
SEND_META0 and SEND_META1 in the General Params table.The implication of this patch is that the AVB Params table will always
be present in the static config. Which doesn't really hurt.This is needed because in a future patch, we will add another field from
this table, CAS_MASTER, for configuring the PTP_CLK pin function. That
can be configured irrespective of whether RX timestamping is enabled or
not, so always having this table present is going to simplify things a
bit.Signed-off-by: Vladimir Oltean

Packet trap groups are now explicitly registered by drivers and not
implicitly registered when the packet traps are registered. Therefore,
there is no need to encode entire group structure the trap is associated
with inside the trap structure.Instead, only pass the group identifier. Refer to it as initial group
identifier, as future patches will allow user space to move traps
between groups.Signed-off-by: Ido Schimmel

====================
100GbE Intel Wired LAN Driver Updates 2020-03-21Implement basic support for the devlink interface in the ice driver.
Additionally pave some necessary changes for adding a devlink region that
exposes the NVM contents.This series first contains 5 patches for enabling and implementing full NVM
read access via the ETHTOOL_GEEPROM interface. This includes some cleanup of
endian-types, a new function for reading from the NVM and Shadow RAM as a flat
addressable space, a function to calculate the available flash size during
load, and a change to how some of the NVM version fields are stored in the
ice_nvm_info structure.Following this is 3 patches for implementing devlink support. First, one patch
which implements the basic framework and introduces the ice_devlink.c file.
Second, a patch to implement basic .info_get support. Finally, a patch which
reads the device PBA identifier and reports it as the `board.id` value in the
.info_get response.

With MTU sized receive buffers it is not expected to have CQE_RX
with multiple receive buffer pointers. But since same physcial link
is shared by PF and it's VFs, the max receive packet configured
at link could be morethan MTU. Hence there is a chance of receiving
plts morethan MTU which then gets DMA'ed into multiple buffers
and notified in a single CQE_RX. This patch treats such pkts as errors
and frees up receive buffers pointers back to hardware.Also on the transmit side this patch sets SMQ MAXLEN to max value to avoid
HW length errors for the packets whose size > MTU, eg due to path MTU.Signed-off-by: Geetha sowjanya

On OcteonTx2 silicon there two two types VFs, VFs that share the
physical link with their parent SR-IOV PF and the VFs which work
in pairs using internal HW loopback channels (LBK). Except for the
underlying Rx/Tx channel mapping from netdev functionality perspective
they are almost identical. This patch adds netdev driver support
for these VFs.Unlike it's parent PF a VF cannot directly communicate with admin
function (AF) and it has to go through PF for the same. The mailbox
communication with AF works like 'VF PF AF'.Also functionality wise VF and PF are identical, hence to avoid code
duplication PF driver's APIs are resued here for HW initialization,
packet handling etc etc ie almost everything. For VF driver to compile
as module exported few of the existing PF driver APIs.Signed-off-by: Subbaraya Sundeep

When FLR is initiated for a VF (PCI function level reset),
the parent PF gets a interrupt. PF then sends a message to
admin function (AF), which then cleanups all resources attached

Added 'sriov_configure' to enable/disable virtual functions (VFs).
Also added handling of mailbox messages from these VFs.Admin function (AF) is the only one with all priviliges to configure
HW, alloc resources etc etc, PFs and it's VFs have to request AF
via mbox for all their needs. But unlike PFs, their VFs cannot
send a mbox request directly. A VF shares a mailbox region with
it's parent PF, so VF sends a mailbox msg to PF and then PF forwards
it to AF. Then AF after processing sends response to PF which it
again forwards to VF.This patch adds support for this 'VF PF AF' mailbox
communication.Signed-off-by: Tomasz Duszynski

easier move the downshift notification to phylib. phy_check_downshift()
