In order to be able to configure all needed stuff on a port/netdevice
of a line card without the line card being present, introduce line card
provisioning. Basically by setting a type, provisioning process will
start and driver is supposed to create a placeholder for instances
(ports/netdevices) for a line card type.
Allow the user to query the supported line card types over line card
get command. Then implement two netlink command SET to allow user to
set/unset the card type.
On the driver API side, add provision/unprovision ops and supported
types array to be advertised. Upon provision op call, the driver should
take care of creating the instances for the particular line card type.
Introduce provision_set/clear() functions to be called by the driver
once the provisioning/unprovisioning is done on its side. These helpers
are not to be called directly due to the async nature of provisioning.
Example:
$ devlink port # No ports are listed
$ devlink lc
pci/0000:01:00.0:
lc 1 state unprovisioned
supported_types:
16x100G

The receiving interface might have used GRO to receive more fragments than
MAX_SKB_FRAGS fragments. In this case, these will not be stored in
skb_shinfo(skb)->frags but merged into the frag list.
batman-adv relies on the function skb_split to split packets up into
multiple smaller packets which are not larger than the MTU on the outgoing
interface. But this function cannot handle frag_list entries and is only
operating on skb_shinfo(skb)->frags. If it is still trying to split such an
skb and xmit'ing it on an interface without support for NETIF_F_FRAGLIST,
then validate_xmit_skb() will try to linearize it. But this fails due to
inconsistent information. And __pskb_pull_tail will trigger a BUG_ON after
skb_copy_bits() returns an error.
In case of entries in frag_list, just linearize the skb before operating on
it with skb_split().

The first attempt to fix a the 'impossible' WARN_ON_ONCE(1) in
isotp_tx_timer_handler() focussed on the identical CAN IDs created by
the syzbot reproducer and lead to upstream fix/commit 3ea566422cbd
("can: isotp: sanitize CAN ID checks in isotp_bind()"). But this did
not catch the root cause of the wrong tx.state in the tx_timer handler.
In the isotp 'first frame' case a timeout monitoring needs to be started
before the 'first frame' is send. But when this sending failed the timeout
monitoring for this specific frame has to be disabled too.
Otherwise the tx_timer is fired with the 'warn me' tx.state of ISOTP_IDLE.

If all completed requests in io_do_iopoll() were marked with
REQ_F_CQE_SKIP, we'll not only skip CQE posting but also
io_free_batch_list() leaking memory and resources.
Move @nr_events increment before REQ_F_CQE_SKIP check. We'll potentially
return the value greater than the real one, but iopolling will deal with
it and the userspace will re-iopoll if needed. In anyway, I don't think
there are many use cases for REQ_F_CQE_SKIP + IOPOLL.

but it also removes last bit from non layer3+4 hashing
Below script shows layer2+3 hashing will result in same slave to be used with above commit.
$ cat hash.py
#/usr/bin/python3.6
h_dests=[0xa0, 0xa1]
h_source=0xe3
hproto=0x8
saddr=0x1e7aa8c0
daddr=0x17aa8c0
for h_dest in h_dests:
hash = (h_dest ^ h_source ^ hproto ^ saddr ^ daddr)
hash ^= hash >> 16
hash ^= hash >> 8
print(hash)
print("with last bit removed")
for h_dest in h_dests:
hash = (h_dest ^ h_source ^ hproto ^ saddr ^ daddr)
hash ^= hash >> 16
hash ^= hash >> 8
hash = hash >> 1

====================
net: Reduce qca8k_priv space usage
These 6 patch is a first attempt at reducting qca8k_priv space.
The code changed a lot during times and we have many old logic
that can be replaced with new implementation
The first patch drop the tracking of MTU. We mimic what was done
for mtk and we change MTU only when CPU port is changed.
The second patch finally drop a piece of story of this driver.
The ar8xxx_port_status struct was used by the first implementation
of this driver to put all sort of status data for the port...
With the evolution of DSA all that stuff got dropped till only
the enabled state was the only part of the that struct.
Since it's overkill to keep an array of int, we convert the variable
to a simple u8 where we store the status of each port. This is needed
to don't reanable ports on system resume.
The third patch is a preparation for patch 4. As Vladimir explained
in another patch, we waste a tons of space by keeping a duplicate of
the switch dsa ops in qca8k_priv. The only reason for this is to
dynamically set the correct mdiobus configuration (a legacy dsa one,
or a custom dedicated one)
To solve this problem, we just drop the phy_read/phy_write and we
declare a custom mdiobus in any case.
This way we can use a static dsa switch ops struct and we can drop it
from qca8k_priv
Patch 4 drop the duplicated dsa_switch_ops.
Patch 5 is a fixup for mdio read error.
Patch 6 is an effort to standardize how bus name are done.
This series is just a start of more cleanup.
The idea is to move this driver to the qca dir and split common code
from specific code. Also the mgmt eth code still requires some love
and can totally be optimized by recycling the same skb over time.
Also while working on the MTU it was notice some problem with
the stmmac driver and with the reloading phase that cause all
sort of problems with qca8k.
I'm sending this here just to try to keep small series instead of
proposing monster series hard to review.

- Drop unrealated changes from patch 3

In an attempt to reduce qca8k_priv space, rework and simplify mdiobus
logic.
We now declare a mdiobus instead of relying on DSA phy_read/write even
if a mdio node is not present. This is all to make the qca8k ops static
and not switch specific. With a legacy implementation where port doesn't
have a phy map declared in the dts with a mdio node, we declare a
'qca8k-legacy' mdiobus. The conversion logic is used as legacy read and
write ops are used instead of the internal one.
Also drop the legacy_phy_port_mapping as we now declare mdiobus with ops
that already address the workaround.

Port_sts is a thing of the past for this driver. It was something
present on the initial implementation of this driver and parts of the
original struct were dropped over time. Using an array of int to store if
a port is enabled or not to handle PM operation seems overkill. Switch
and use a simple u8 to store the port status where each bit correspond
to a port. (bit is set port is enabled, bit is not set, port is disabled)
Also add some comments to better describe why we need to track port
status.

DSA set the CPU port based on the largest MTU of all the slave ports.

Pull ARM SoC fixes from Arnd Bergmann:
"There are a number of SoC bugfixes that came in since the merge
window, and more of them are already pending.
This batch includes:
- A boot time regression fix for davinci that triggered on
multi_v5_defconfig when booting any platform
- Defconfig updates to address removed features, changed symbol names
or dependencies, for gemini, ux500, and pxa
- Email address changes for Krzysztof Kozlowski
- Build warning fixes for ep93xx and iop32x
- Devicetree warning fixes across many platforms
- Minor bugfixes for the reset controller, memory controller and SCMI
firmware subsystems plus the versatile-express board"

git://git.kernel.org/pub/scm/linux/kernel/git/crng/random
Pull random number generator fixes from Jason Donenfeld:
- Per your suggestion, random reads now won't fail if there's a page
fault after some non-zero amount of data has been read, which makes
the behavior consistent with all other reads in the kernel.
- Rather than an inconsistent mix of random_get_entropy() returning an
unsigned long or a cycles_t, now it just returns an unsigned long.
- A memcpy() was replaced with an memmove(), because the addresses are
sometimes overlapping. In practice the destination is always before
the source, so not really an issue, but better to be correct than
not.

This register write to REG_INTF_CONFIG6 enables a spike filter that
is impacting the line and can prevent the I2C ACK to be seen by the
controller. So we don't test the return value.

In order to immediately overwrite the old key on the stack, before
servicing a userspace request for bytes, we use the remaining 32 bytes
of block 0 as the key. This means moving indices 8,9,a,b,c,d,e,f ->
4,5,6,7,8,9,a,b. Since 4 < 8, for the kernel implementations of
memcpy(), this doesn't actually appear to be a problem in practice. But
relying on that characteristic seems a bit brittle. So let's change that
to a proper memmove(), which is the by-the-books way of handling
overlapping memory copies.
