Pull networking fixes from David Miller:
1) Handle multicast packets properly in fast-RX path of mac80211, from
Johannes Berg.
2) Because of a logic bug, the user can't actually force SW
checksumming on r8152 devices. This makes diagnosis of hw
checksumming bugs really annoying. Fix from Hayes Wang.
3) VXLAN route lookup does not take the source and destination ports
into account, which means IPSEC policies cannot be matched properly.
Fix from Martynas Pumputis.
4) Do proper RCU locking in netvsc callbacks, from Stephen Hemminger.
5) Fix SKB leaks in mlxsw driver, from Arkadi Sharshevsky.
6) If lwtunnel_fill_encap() fails, we do not abort the netlink message
construction properly in fib_dump_info(), from David Ahern.
7) Do not use kernel stack for DMA buffers in atusb driver, from Stefan
Schmidt.
8) Openvswitch conntack actions need to maintain a correct checksum,
fix from Lance Richardson.
9) ax25_disconnect() is missing a check for ax25->sk being NULL, in
fact it already checks this, but not in all of the necessary spots.
Fix from Basil Gunn.
10) Action GET operations in the packet scheduler can erroneously bump
the reference count of the entry, making it unreleasable. Fix from
Jamal Hadi Salim. Jamal gives a great set of example command lines
that trigger this in the commit message.

The conversion to the new hotplug state machine introduced a regression
where a successful hotplug registration would be treated as an error,
effectively disabling the MSI driver forever.

When a CPU goes offline a potentially pending timer interrupt is not
cleared. When the CPU comes online again then the pending interrupt is
delivered before the per cpu clockevent device is initialized. As a

When running SRIOV, warnings for SRQ LIMIT events flood the Hypervisor's
message log when (correct, normally operating) apps use SRQ LIMIT events
as a trigger to post WQEs to SRQs.

transitions
Save the qp context flags byte containing the flag disabling vlan stripping
in the RESET to INIT qp transition, rather than in the INIT to RTR
transition. Per the firmware spec, the flags in this byte are active
in the RESET to INIT transition.
As a result of saving the flags in the incorrect qp transition, when
switching dynamically from VGT to VST and back to VGT, the vlan
remained stripped (as is required for VST) and did not return to
not-stripped (as is required for VGT).

In function mlx4_cq_completion() and mlx4_cq_event(), the
radix_tree_lookup requires a rcu_read_lock.
This is mandatory: if another core frees the CQ, it could
run the radix_tree_node_rcu_free() call_rcu() callback while
its being used by the radix tree lookup function.
Additionally, in function mlx4_cq_event(), since we are adding
the rcu lock around the radix-tree lookup, we no longer need to take
the spinlock. Also, the synchronize_irq() call for the async event
eliminates the need for incrementing the cq reference count in
mlx4_cq_event().
Other changes:
1. In function mlx4_cq_free(), replace spin_lock_irq with spin_lock:
we no longer take this spinlock in the interrupt context.
The spinlock here, therefore, simply protects against different
threads simultaneously invoking mlx4_cq_free() for different cq's.
2. In function mlx4_cq_free(), we move the radix tree delete to before
the synchronize_irq() calls. This guarantees that we will not
access this cq during any subsequent interrupts, and therefore can
safely free the CQ after the synchronize_irq calls. The rcu_read_lock
in the interrupt handlers only needs to protect against corrupting the
radix tree; the interrupt handlers may access the cq outside the
rcu_read_lock due to the synchronize_irq calls which protect against
premature freeing of the cq.
3. In function mlx4_cq_event(), we change the mlx_warn message to mlx4_dbg.
4. We leave the cq reference count mechanism in place, because it is
still needed for the cq completion tasklet mechanism.

As found by Olof's build bot, we gain a harmless warning about a
potential uninitialized variable reference in mlx5:
drivers/net/ethernet/mellanox/mlx5/core/en_tc.c: In function 'parse_tc_fdb_actions':
drivers/net/ethernet/mellanox/mlx5/core/en_tc.c:769:13: warning: 'out_dev' may be used uninitialized in this function [-Wmaybe-uninitialized]
drivers/net/ethernet/mellanox/mlx5/core/en_tc.c:811:21: note: 'out_dev' was declared here
This was introduced through the addition of an 'IS_ERR/PTR_ERR' pair
that gcc is unfortunately unable to completely figure out.
The problem being gcc cannot tell that if(IS_ERR()) in
mlx5e_route_lookup_ipv4() is equivalent to checking if(err) later,
so it assumes that 'out_dev' is used after the 'return PTR_ERR(rt)'.
The PTR_ERR_OR_ZERO() case by comparison is fairly easy to detect
by gcc, so it can't get that wrong, so it no longer warns.
Hadar Hen Zion already attempted to fix the warning earlier by adding fake
initializations, but that ended up not fully addressing all warnings, so
I'm reverting it now that it is no longer needed.

Currently dp83867 driver returns error if phy interface type
PHY_INTERFACE_MODE_RGMII_RXID is used to set the rx only internal
delay. Similarly issue happens for PHY_INTERFACE_MODE_RGMII_TXID.
Fix this by checking also the interface type if a particular delay
value is missing in the phy dt bindings. Also update the DT document
accordingly.

During interface opening MAC address stored in netdev->dev_addr is
programmed in the HW with exception of BE3 VFs where the initial
MAC is programmed by parent PF. This is OK when MAC address is not
changed when an interfaces is down. In this case the requested MAC is
stored to netdev->dev_addr and later is stored into HW during opening.
But this is not done for all BE3 VFs so the NIC HW does not know
anything about this change and all traffic is filtered.
This is the case of bonding if fail_over_mac == 0 where the MACs of
the slaves are changed while they are down.
The be2net behavior is too restrictive because if a BE3 VF has
the FILTMGMT privilege then it is able to modify its MAC without
any restriction.
To solve the described problem the driver should take care about these
privileged BE3 VFs so the MAC is programmed during opening. And by
contrast unpriviled BE3 VFs should not be allowed to change its MAC
in any case.

The #warning was present 10 years ago when the driver first got merged.
As the platform is rather obsolete by now, it seems very unlikely that
the warning will cause anyone to fix the code properly.
kernelci.org reports the warning for every build in the meantime, so
I think it's better to just turn it into a code comment to reduce
noise.

Due to alignment requirements of the hardware transmissions are split into
two DMA descriptors, a small padding descriptor of 0 - 3 bytes in length
followed by a descriptor for rest of the packet.
In the case of IP packets the first descriptor will never be zero due to
the way that the stack aligns buffers for IP packets. However, for non-IP
packets it may be zero.
In that case it has been reported that timeouts occur, presumably because
transmission stops at the first zero-length DMA descriptor and thus the
packet is not transmitted. However, in my environment a BUG is triggered as
follows:

Regressions for not being able to detect an eMMC HS DDR mode card has been
reported for the sdhci-esdhc-imx driver, but potentially other sdhci
variants may suffer from the similar problem.
The commit e173f8911f09 ("mmc: core: Update CMD13 polling policy when
switch to HS DDR mode"), is causing the problem. It seems that change moved
one step to far, regarding changing the host's timing before polling for a
busy card.
To fix this, let's move back to the behaviour when the host's timing is
updated after the polling, but before the switch status is fetched and
validated.
In cases when polling with CMD13, we keep validating the switch status at
each attempt. However, to align with the other card busy detections
mechanism, let's fetch and validate the switch status also after the host's
timing is updated.

USBTrdTim must be programmed to 0x5 when phy has a UTMI+ 16-bit wide
interface or 0x9 when it has a 8-bit wide interface.
GUSBCFG reset value (Value After Reset: 0x1400) sets USBTrdTim to 0x5.
In case of 8-bit UTMI+, without clearing GUSBCFG.USBTRDTIM mask, USBTrdTim
results in 0xD (0x5 | 0x9).
That's why we need to clear GUSBCFG.USBTRDTIM mask before setting USBTrdTim
value, to ensure USBTrdTim is correctly set in case of 8-bit UTMI+.

Without that we'll pass a wrong payload size in cmd->sdb, which
can lead to hangs with drivers that need the total transfer size.

"The major fix is the bfa firmware, since the latest 10Gb cards fail
probing with the current firmware.
The rest is a set of minor fixes: one missed Kconfig dependency
causing randconfig failures, a missed error return on an error leg, a
change for how multiqueue waits on a blocked device and a don't reset
while in reset fix"

platform device"
Commit 72a9b186292d ("xen: Remove event channel notification through Xen
PCI platform device") broke Linux when booting as Dom0 on Xen in a
nested Xen environment (Xen installed inside a Xen VM). In this
scenario, Linux is a PV guest, but at the same time it uses the
platform-pci driver to receive notifications from L0 Xen. vector
callbacks are not available because L1 Xen doesn't allow them.
Partially revert the offending commit, by restoring IRQ based
notifications for PV guests only. I restored only the code which is
strictly needed and replaced the xen_have_vector_callback checks within
it with xen_pv_domain() checks.

Commit 98a29c39dc68 ("libnvdimm, namespace: allow creation of multiple
pmem-namespaces per region") added support for establishing additional
pmem namespace beyond the seed device, similar to blk namespaces.
However, it neglected to delete the namespace when the size is set to
zero.

The __bcm_sysport_tx_reclaim() function is used to reclaim transmit
resources in different places within the driver. Most of them should
not affect the state of the transit flow control.
Introduce bcm_sysport_tx_clean() which cleans the ring, but does not
re-enable flow control towards the networking stack, and make
bcm_sysport_tx_reclaim() do the actual transmit queue flow control.

Make sure to check for short control transfers in order to avoid parsing
uninitialised buffer data and leaking it to user space.
Note that the backlight and macro-mode buffer constraints are kept as
loose as possible in order to avoid any regressions should the current
buffer sizes be larger than necessary.

Not all platforms support DMA to the stack, and specifically since v4.9
this is no longer supported on x86 with VMAP_STACK either.

The slave mapping should be removed together with other channel

The read_pmem() function uses memcpy_mcsafe() on x86 where an EFAULT
error code indicates a failed read. Block I/O should use EIO to
indicate failure. Other pmem code paths (like bad blocks) already use
EIO so let's be consistent.
This fixes compatibility with consumers like btrfs that try to parse the
specific error code rather than treat all errors the same.

Before the mdev enhancement type1 iommu used capable() to test the
capability of current task; in the course of mdev development a
new requirement, testing for another task other than current, was
raised. ns_capable() was used for this purpose, however it still
tests current, the only difference is, in a specified namespace.
Fix it by using has_capability() instead, which tests the cap for
specified task in init_user_ns, the same namespace as capable().

While probing BGX we requesting appropriate QLM for it's configuration
and get LMAC count by that request. Then, while reading configured
MAC values from SSDT table we need to save them in proper mapping:
BGX[i]->lmac[j].mac = <MAC value>
to later provide for initialization stuff. In order to fill
such mapping properly we need to add lmac index to be used while
acpi initialization since at this moment bgx->lmac_count already contains
actual value.
