The private structure contain a pointer to phydev, but the structure
net_device already contain such pointer. So we can remove the pointer
phy_dev in the private structure, and update the driver to use the
one contained in struct net_device.

Since commit 4f0087812648 ("sctp: apply rhashtable api to send/recv
path"), sctp uses transport rhashtable with .obj_cmpfn sctp_hash_cmp,
in which it compares the members of the transport with the rhashtable
args to check if it's the right transport.
But sctp uses the transport without holding it in sctp_hash_cmp, it can
cause a use-after-free panic. As after it gets transport from hashtable,
another CPU may close the sk and free the asoc. In sctp_association_free,
it frees all the transports, meanwhile, the assoc's refcnt may be reduced
to 0, assoc can be destroyed by sctp_association_destroy.
So after that, transport->assoc is actually an unavailable memory address
in sctp_hash_cmp. Although sctp_hash_cmp is under rcu_read_lock, it still
can not avoid this, as assoc is not freed by RCU.
This patch is to hold the transport before checking it's members with
sctp_transport_hold, in which it checks the refcnt first, holds it if
it's not 0.

When system enters into kdump kernel because of kernel panic, it won't
shutdown devices. On-flight DMA will continue transferring data until
device driver initializes. All devices are supposed to reset during
driver initialization. And this property is used to fix the kdump
failure in system with intel iommu. Other systems with hardware iommu
should be similar. Please check commit 091d42e ("iommu/vt-d: Copy
translation tables from old kernel") and those commits around.
But bnx2 driver doesn't reset device during driver initialization. The
device resetting is deferred to net device up stage. This will cause
hardware iommu handling failure on bnx2 device. And its resetting relies
on firmware. So in this patch move the firmware requesting code to earlier
bnx2_init_one(), then next call bnx2_reset_chip to reset device.

If /sbin/bridge-stp is available on the system, bridge tries to execute
it instead of the kernel implementation when starting/stopping STP.
If anything goes wrong with /sbin/bridge-stp, bridge silently falls back
to kernel STP, making hard to debug userspace STP.
This patch adds a br_stp_call_user helper to start/stop userspace STP
and debug errors from the program: abnormal exit status is stored in the
lower byte and normal exit status is stored in higher byte.
Below is a simple example on a kernel with dynamic debug enabled:
# ln -s /bin/false /sbin/bridge-stp
# brctl stp br0 on
br0: failed to start userspace STP (256)
# dmesg
br0: /sbin/bridge-stp exited with code 1
br0: failed to start userspace STP (256)
br0: using kernel STP

====================
Netfilter fixes for net
The following patchset contains Netfilter fixes for your net tree,
they are:
1) Endianess fix for the new nf_tables netlink trace infrastructure,
NFTA_TRACE_POLICY endianess was not correct, patch from Liping Zhang.
2) Fix broken re-route after userspace queueing in nf_tables route
chain. This patch is large but it is simple since it is just getting
this code in sync with iptable_mangle. Also from Liping.
3) NAT mangling via ctnetlink lies to userspace when nf_nat_setup_info()
fails to setup the NAT conntrack extension. This problem has been
there since the beginning, but it can now show up after rhashtable
conversion.
4) Fix possible NULL pointer dereference due to failures in allocating
the synproxy and seqadj conntrack extensions, from Gao feng.

aic5_irq_domain_xlate() and aic_irq_domain_xlate() take the generic chip
lock without disabling interrupts, which can lead to a deadlock if an
interrupt occurs while the lock is held in one of these functions.
Replace irq_gc_{lock,unlock}() calls by
irq_gc_{lock_irqsave,unlock_irqrestore}() ones to prevent this bug from
happening.

Some irqchip drivers need to take the generic chip lock outside of the
irq context.
Provide the irq_gc_{lock_irqsave,unlock_irqrestore}() helpers to allow
one to disable irqs while entering a critical section protected by
gc->lock.
Note that we do not provide optimized version of these helpers for !SMP,
because they are not called from the hot-path.

hw_4addr_pad was added to handle different types of padding
in 4-address rx frame. But this padding is not very specific
to 4-address, it can happen even with three address + ethernet
decap mode. Since the padding information can be obtained
through Rx desc for QCA99X0 and newer chips, this hw_param
is not needed any more.

In QCA99X0 (QCA99X0, QCA9984, QCA9888 and QCA4019) family chips,
hw adds padding at the begining of the rx payload to make L3
header 4-byte aligned. In the chips doing this type of padding,
the number of bytes padded will be indicated through msdu_end:info1.
Define a hw_rx_desc_ops wrapper to retrieve the number of padded
bytes and use this while doing undecap. This should fix padding
related issues with ethernt decap format with QCA99X0, QCA9984,
QCA9888 and QCA4019 hw.

There are slight differences in Rx hw descriptor information
among different chips. So far driver does not use those new
information for any functionalities, but there is one important
information which is available from QCA99X0 onwards to indicate
the number of bytes that hw padded at the begining of the rx
payload and this information is needed to undecap the rx
packet. Add an abstraction for Rx desc to make use of the
new desc information available. The callback that this patch
defines to retrieve the padding bytes will be used in follow-up
patch.

IFTYPE_MESH_POINT need to rely on these for accurate path
selection metrics. Other modes will probably also find
them useful. Enabling peer stats has the side effect of
reducing max number of STAs from 128 to 118. There should
be negligible performance impact.
If users really need 128 STAs and don't mind losing out on
peer stats, they can still disable them:

The AES-CTR glue code avoids calling into the blkcipher API for the
tail portion of the walk, by comparing the remainder of walk.nbytes
modulo AES_BLOCK_SIZE with the residual nbytes, and jumping straight
into the tail processing block if they are equal. This tail processing
block checks whether nbytes != 0, and does nothing otherwise.
However, in case of an allocation failure in the blkcipher layer, we
may enter this code with walk.nbytes == 0, while nbytes > 0. In this
case, we should not dereference the source and destination pointers,
since they may be NULL. So instead of checking for nbytes != 0, check
for (walk.nbytes % AES_BLOCK_SIZE) != 0, which implies the former in
non-error conditions.

smatch pointed out that the second check of "tdls_auth" was
pointless since if it was true, we returned from the function
already. We can further simplify the code by moving the first
check (if it's a TDLS peer at all) into the outer if, to only
handle that inside. This simplifies the control flow here.

Currently the 'aqm' stats in mac80211 only keeps overlimit drop stats,
not CoDel stats. This moves the CoDel stats into the txqi structure to
keep them per txq in order to show them in debugfs.
In addition, the aqm debugfs output is restructured by splitting it up
into three files: One global per phy, one per netdev and one per
station, in the appropriate directories. The files are all called aqm,
and are only created if the driver supports the wake_tx_queue op (rather
than emitting an error on open as previously).
