Four qdisc chose to call their own ops->destroy(), assuming their caller

This patch makes sure qdisc_create() calls ops->destroy()

Jakub Kicinski says:
====================
Netronome NFP4000 and NFP6000 PF driver
This is a base PF driver for Netronome NFP4000 and NFP6000 chips. This
series doesn't add any exciting new features, it provides a foundation
for supporting more advanced firmware applications.
Patch 1 moves a bitfield-related helper from our BPF code to the global
header.
Patch 2 renames the kernel module and adds a new main file. We were
considering 3-module approach (pf, vf, common netdev library) but
ultimately settled on a single module to keep things simple.
Patch 3 adds support for accessing chip internals. It provides a way of
configuring access windows to different parts of chip memory and issuing
pretty much any commands on chip's NoC.
Patches 4, 5, 6, 7, 8 provide support for accessing and interpreting
various hardware and firmware information structures.
Patch 9 introduces service processor (NSP) ABI. This ABI gives us
access to PHY/SFP module configuration and information as well as
methods for unloading and loading application firmware.
Patches 10 and 11 modify the existing netdev code to make it possible
to support multi-port devices (sharing a PCI device).
Patch 12 adds a new driver probe path which will be used for the PF
PCI device IDs. It utilizes the newly added infrastructure and is able
to load application FW and spawn netdevs for all card's ports.

net: dsa: remove unnecessary phy.h include
Including phy.h and phy_fixed.h into net/dsa.h causes phy*.h to be an
unnecessary dependency for quite a large amount of the kernel. There's
very little which actually requires definitions from phy.h in net/dsa.h
- the include itself only wants the declaration of a couple of
structures and IFNAMSIZ.
Add linux/if.h for IFNAMSIZ, declarations for the structures, phy.h to
mv88e6xxx.h as it needs it for phy_interface_t, and remove both phy.h
and phy_fixed.h from net/dsa.h.
This patch reduces from around 800 files rebuilt to around 40 - even
with ccache, the time difference is noticable.
In order to make this change, several drivers need to be updated to
include necessary headers that they were picking up through this
include. This has resulted in a much larger patch series.
I'm assuming the 0-day builder has had 24 hours with this series, and
hasn't reported any further issues with it - the last issue was two
weeks ago (before I became ill) which I fixed over the last weekend.

MIPS: Octeon: Remove unnecessary MODULE_*()
octeon-platform.c can not be built as a module for two reasons:
(a) the Makefile doesn't allow it:
obj-y := cpu.o setup.o octeon-platform.o octeon-irq.o csrc-octeon.o
(b) the multiple *_initcall() statements, each of which are translated
to a module_init() call when attempting a module build, become
aliases to init_module(). Having more than one alias will cause a
build error.
Hence, rather than adding a linux/module.h include, remove the redundant
MODULE_*() from this file.

NET: mkiss: Fix panic
If a USB-to-serial adapter is unplugged, the driver re-initializes, with
dev->hard_header_len and dev->addr_len set to zero, instead of the correct
values. If then a packet is sent through the half-dead interface, the
kernel will panic due to running out of headroom in the skb when pushing
for the AX.25 headers resulting in this panic:
[<
c0595468>] (skb_panic) from [<
c0401f70>] (skb_push+0x4c/0x50)
[<
c0401f70>] (skb_push) from [<
bf0bdad4>] (ax25_hard_header+0x34/0xf4 [ax25])
[<
bf0bdad4>] (ax25_hard_header [ax25]) from [<
bf0d05d4>] (ax_header+0x38/0x40 [mkiss])
[<
bf0d05d4>] (ax_header [mkiss]) from [<
c041b584>] (neigh_compat_output+0x8c/0xd8)
[<
c041b584>] (neigh_compat_output) from [<
c043e7a8>] (ip_finish_output+0x2a0/0x914)
[<
c043e7a8>] (ip_finish_output) from [<
c043f948>] (ip_output+0xd8/0xf0)
[<
c043f948>] (ip_output) from [<
c043f04c>] (ip_local_out_sk+0x44/0x48)
This patch makes mkiss behave like the 6pack driver. 6pack does not
panic. In 6pack.c sp_setup() (same function name here) the values for
dev->hard_header_len and dev->addr_len are set to the same values as in
my mkiss patch.

net: hns: Fix the device being used for dma mapping during TX
This patch fixes the device being used to DMA map skb->data.
Erroneous device assignment causes the crash when SMMU is enabled.
This happens during TX since buffer gets DMA mapped with device
correspondign to net_device and gets unmapped using the device
related to DSAF.
