The pci_error_handlers->reset_notify() method had a flag to indicate
whether to prepare for or clean up after a reset. The prepare and done
cases have no shared functionality whatsoever, so split them into separate
methods.

Pull networking fixes from David Miller:
"Mostly fixing some light fallout from the changes that went into the
merge window.
1) Fix memory leaks on network namespace teardown in netfilter, from
Liping Zhang.
2) When comparing ipv6 nexthops, we have to take the lightweight
tunnel state into account as well. From David Ahern.
3) Fix socket option object length check in the new TLS code, from
Matthias Rosenfelder.
4) Fix memory leak in nfp driver flower support, from Jakub Kicinski.
5) Several netlink attribute validation fixes in cfg80211, from
Srinivas Dasari.
6) Fix context array leak in virtio_net, from Jason Wang.
7) SKB use after free in hns driver, from Yusheng Lin.
8) Fix socket leak on accept() in RDS, from Sowmini Varadhan. Also
add a WARN_ON() to sock_graft() so other protocol stacks don't
trip over this as well"

Remove useless local variables _match_, _soc_ and the code related.
Notice that
const struct of_device_id of_mtk_match[] = {
{ .compatible = "mediatek,mt2701-eth" },
{},
};
So match->data is NULL.

As per the SAMA5D3 device specification it supports Jumbo frames.
But the suggested flag and length of bytes it supports was not updated
in this driver config_structure.
The maximum jumbo frames the device supports :
10240 bytes as per the device spec.
While changing the MTU value greater than 1500, it threw error:
sudo ifconfig eth1 mtu 9000
SIOCSIFMTU: Invalid argument
Add this support to driver so that it works as expected and designed.

resulting in an inability to detect a soft reset failure. Fix it by using

Pull dma-mapping infrastructure from Christoph Hellwig:
"This is the first pull request for the new dma-mapping subsystem
In this new subsystem we'll try to properly maintain all the generic
code related to dma-mapping, and will further consolidate arch code
into common helpers.
This pull request contains:
- removal of the DMA_ERROR_CODE macro, replacing it with calls to
->mapping_error so that the dma_map_ops instances are more self
contained and can be shared across architectures (me)
- removal of the ->set_dma_mask method, which duplicates the
->dma_capable one in terms of functionality, but requires more
duplicate code.
- various updates for the coherent dma pool and related arm code
(Vladimir)
- various smaller cleanups (me)"

ABI 4.x introduced the chained metadata format and made it the
only one possible. There are cases, however, where the old
format is preferred - mostly to make interoperation with VFs
using ABI 3.x easier for the datapath. In ABI 5.x we allowed
for more flexibility by selecting the metadata format based
on capabilities. The default was left to non-chained.
In case of fallback traffic, there is no capability telling the
driver there may be chained metadata. With a very stripped-
-down FW the default old metadata format would be selected
making the driver drop all fallback traffic.
This patch changes the default selection in the driver. It
should not hurt with old firmwares, because if they don't
advertise RSS they will not produce metadata anyway. New
firmwares advertising ABI 5.x, however, can depend on the
driver defaulting to chained format.

The legacy MAC address lookup doesn't work well with breakout
cables. We are probably better off picking random addresses
than the wrong ones in the theoretical scenario where management
FW didn't tell us what the port config is.

For historical reasons we enumerate the vNICs in order. This means
that if user configures breakout on a multiport card, the first
interface of the second port will have its MAC address changed.
What's worse, when moved from static information (HWInfo) to using
management FW (NSP), more features started depending on the port ids.
Right now in case of breakout first subport of the second port and
second subport of the first port will have their link info swapped.
Revise the ordering scheme so that first subport maintains its address.
Side effect of this change is that we will use base lane ids in
devlink (i.e. 40G ports will be 4 ids apart), e.g.:
pci/0000:04:00.0/0: type eth netdev p6p1
pci/0000:04:00.0/4: type eth netdev p6p2
Note that behaviour of phys_port_id is not changed since there is
a separate id number for the subport there.

====================
Mellanox, mlx5 fixes 2017-06-28
This series contains some fixes for the mlx5 core and netdev driver.
Please pull and let me know if there's any problem.
For -stable:
("net/mlx5e: Fix TX carrier errors report in get stats ndo") Kernels >= v4.7
("net/mlx5: Cancel delayed recovery work when unloading the driver") Kernels >= v4.10
* When applied to net-next this will introduce a contextual conflict, it
should be easy to resolve, (a spin_lock was changed to spin_lock_irqsave in net-next),
if you need any help with this please let me know.
("net/mlx5: Fix driver load error flow when firmware is stuck") Kernels >= v4.4*
* This patch fixes: 6c780a0267b8 ("net/mlx5: Wait for FW readiness before initializing command interface")
which was submitted two weeks ago and queued up for v4.4.
Sorry about the mess, but other than the above, this series doesn't introduce
any conflict with the current mlx5 IPSec offload series.

This patch adds the ability to add and remove listeners and identify
whether the SYN packet received is intended for iWARP or not. If
a listener is not found the SYN packet is posted back to the chip.

iWARP handles incoming SYN packets using the ll2 interface. This patch
implements ll2 setup and teardown. Additional ll2 connections will
be used in the future which are not part of this patch series.

This patch adds iWARP support for flows that have common code
between RoCE and iWARP, such as initialization, teardown and
qp setup verbs: create, destroy, modify, query.
It introduces the iWARP specific files qed_iwarp.[ch] and
iwarp_common.h

iWARP personality introduced the need for differentiating in several
places in the code whether we are RoCE, iWARP or either. This
leads to introducing new macros for querying the personality.

Previously the flower offloads never sends messages to the hardware,
and never registers a handler for receiving messages from hardware.
This patch enables the flower offloads to send control messages to
hardware when adding and removing flow rules. Additionally it
registers a control message rx handler for receiving stats updates
from hardware for each offloaded flow.
Additionally this patch adds 4 control message types; Add, modify and
delete flow, as well as flow stats. It also allows
nfp_flower_cmsg_get_data() to be used outside of cmsg.c.

Previously there was no way of updating flow rule stats after they
have been offloaded to hardware. This is solved by keeping track of
stats received from hardware and providing this to the TC handler
on request.

Adds metadata describing the mask id of each flow and keeps track of
flows installed in hardware. Previously a flow could not be removed
from hardware as there was no way of knowing if that a specific flow
was installed. This is solved by storing the offloaded flows in a
hash table.
