This patch fixes that by using the struct device in platform_device

net: of_phy_connect_fixed_link removal
This patch set removes of_phy_connect_fixed_link() from the tree now that
we have a better solution for dealing with fixed PHY (emulated PHY) devices
for drivers that require them.
First two patches update the 'fixed-link' Device Tree binding and drivers to
refere to it.
Patches 3 to 7 update the in-tree network drivers that use
of_phy_connect_fixed_link()
Patch 8 removes of_phy_connect_fixed_link
Patch 9 removes the PowerPC code that parsed the 'fixed-link' property.
Patch 9 can be merged via the net-next tree if the PowerPC folks ack it,
but it really has to be merged after the first 8 patches in order to avoid
breakage.

Parsing and registration of fixed PHY devices was needed with the use of
of_phy_connect_fixed_link() because this function was using the
designated PHY address identifier (first cell of the property) as the
address to bind the PHY on the emulated bus.
Since commit 3be2a49e5c ("of: provide a
binding for fixed link PHYs") a new pair of functions has been
introduced which allows for dynamic address allocation of these fixed
PHY devices, but also parses the old 'fixed-link' 5-digit property.
Registration of fixed PHY early in platform code was needed because we
could not issue a fixed MDIO bus re-scan within network drivers. The
fixed PHYs had to be registered before the network drivers would call
of_phy_connect_fixed_link(). All of these caveats are solved now, such
that we can safely remove of_add_fixed_phys() now.

I've been thinking about it some more and I believe what I proposed is
correct: features that are or-ed (ONE_FOR_ALL) should start with 0,
those which are and-ed (ALL_FOR_ALL) with 1.
But once we do that, we have to fix another problem in vlan module:
features of a vlan device are mostly computed as bitwise AND of features
and vlan_features of its underlying device. The problem is checksumming
features don't really behave like independent flags as their main
purpose is to be used in can_checksum_protocol() whose logic is that
HW_CSUM (GEN_CSUM) means "can checksum everything" so that it kind of
contains IP(V6)_CSUM functionality. Therefore intersection of HW_CSUM
and IP(V6)_CSUM should result in the latter.
An alternative approach would be to always set IP(V6)_CSUM once HW_CSUM
(any of GEN_CSUM) is set but as for long time people were taught not to
do that and we even have a warning for it, switching to the exact
opposite could cause a lot of problems.

__team_compute_features() uses netdev_increment_features() to

As netdev_increment_features() only adds most features and we

Initialize vlan_features only with the flags which are both in

When combining real_dev's features and vlan_features, simple
bitwise AND is used. This doesn't work well for checksum
offloading features as if one set has NETIF_F_HW_CSUM and the
other NETIF_F_IP_CSUM and/or NETIF_F_IPV6_CSUM, we end up with
no checksum offloading. However, from the logical point of view
(how can_checksum_protocol() works), NETIF_F_HW_CSUM contains
the functionality of NETIF_F_IP_CSUM and NETIF_F_IPV6_CSUM so
that the result should be IP/IPV6.
Add helper function netdev_intersect_features() implementing
this logic and use it in vlan_dev_fix_features().

====================
net: Introduce a software TSO helper API
Here's a first proposal for a generic software TSO helper API, following
David's suggestion.
There are at least two drivers that currently implement some form of software
TSO: Solarflare network driver (drivers/net/ethernet/sfc) and Tilera GX
network driver (drivers/net/ethernet/tile/tilegx.c).
The rationale behind adding a generic API is to provide a boiler plate with the
segmentation and other common tasks, making this support easier to add in other
drivers.
When designing the API, I've considered mainly two design choices:
1. Implement a series of callbacks that each driver would implement
and the net core code would call to fill in descriptors and egress
that data.
2. Implement an API for drivers to use in a driver's specific tx_tso
function. This functions would exhaust a sk_buff payload, and use the
API as helper for building the headers and segmented data.
I've chosen (2), to avoid function pointers (which was Willy's concern) and
because it seemed less fragile. Of course, this is argueable.
The API is by no means complete, and lacks some features, however it allows
to support TSO in mv643xx_eth and mvneta network drivers with some very
good performance results. I've added this support as an example of the API
in action.
In particular the following needs some revisiting:
1. IPv6 support is lacking.
2. The required descriptor counting needs some verification. The current
implementation might be too "sketchy". The tilegx one can be a good
starting point.
3. The implemenation assumes the hardware can compute the TCP and IP
checksums for the built headers. However, some controllers may need
some initial calculation (such as tilegx, for instance).
Despite this, I hope this proposal is good enough to trigger some discussion
and to check if I'm on the right track. Feedback is much appreciated!

This is the NFC pull request for 3.16. We have:
- STMicroeectronics st21nfca support. The st21nfca is an HCI chipset and
thus relies on the HCI stack. This submission provides support for tag
redaer/writer mode (including Type 5) and device tree bindings.
- PM runtime support and a bunch of bug fixes for TI's trf7970a.
- Device tree support for NXP's pn544. Legacy platform data support is
obviously kept intact.
- NFC Tag type 4B support to the NFC Digital stack.
- SOCK_RAW type support to the raw NFC socket, and allow NCI
sniffing from that. This can be extended to report HCI frames and also
proprietarry ones like e.g. the pn533 ones."

Netfilter/nftables updates for net-next
The following patchset contains Netfilter/nftables updates for net-next,
most relevantly they are:
1) Add set element update notification via netlink, from Arturo Borrero.
2) Put all object updates in one single message batch that is sent to
kernel-space. Before this patch only rules where included in the batch.
This series also introduces the generic transaction infrastructure so
updates to all objects (tables, chains, rules and sets) are applied in
an all-or-nothing fashion, these series from me.
3) Defer release of objects via call_rcu to reduce the time required to
commit changes. The assumption is that all objects are destroyed in
reverse order to ensure that dependencies betweem them are fulfilled
(ie. rules and sets are destroyed first, then chains, and finally
tables).
4) Allow to match by bridge port name, from Tomasz Bursztyka. This series
include two patches to prepare this new feature.
5) Implement the proper set selection based on the characteristics of the
data. The new infrastructure also allows you to specify your preferences
in terms of memory and computational complexity so the underlying set
type is also selected according to your needs, from Patrick McHardy.
6) Several cleanup patches for nft expressions, including one minor possible
compilation breakage due to missing mark support, also from Patrick.
