50a0ffaf75 net: cdc_ncm/cdc_mbim: rework probing of NCM/MBIM functions
The NCM class match in the cdc_mbim driver is confusing and
cause unexpected behaviour. The USB core guarantees that a
USB interface is in altsetting 0 when probing starts. This
means that devices implementing a NCM 1.0 backwards
compatible MBIM function (a "NCM/MBIM function") always hit
the NCM entry in the cdc_mbim driver match table. Such
functions will never match any of the MBIM entries.

This causes unexpeced behaviour for cases where the NCM and
MBIM entries are differet, which is currently the case for
all except Ericsson devices.

Improve the probing of NCM/MBIM functions by looking up the
device again in the cdc_mbim match table after switching to
the MBIM identity.

The shared altsetting selection is updated to better
accommodate the new probing logic, returning the preferred
altsetting for the control interface instead of the data
interface. The control interface altsetting update is moved
to the cdc_mbim driver. It is never necessary to change the
control interface altsetting for NCM.

6e1b3095dd net: cdc_mbim: reject IP packets on DSS VLANs
DSS VLANs are pseudo network interfaces representing arbitrary
data streams, and specifically not IP. Preventing spurious IP
packets can sometimes be a hassle. The kernel will for example
send an IPv6 Router Solicit when the interface is brought up
unless the user has been careful enough to disable IPv6 first.
Such packets forwared to a MBIM DSS session will look like
spurious noise to the device, and can cause it to log an error
or even malfunction.

Drop all IP packets on the designated DSS VLANs to prevent such
unwanted spurious transmissions.

146a08d2d6 net: cdc_mbim: optionally use VLAN ID 4094 for IP session 0
The cdc_mbim driver maps 802.1q VLANs to MBIM IP and DSS
sessions. MBIM IP session 0 is handled as an exception and
is mapped to untagged frames.

This patch adds optional support for remapping MBIM IP
session 0 to 802.1q VLAN ID 4094 instead. The default
behaviour is not changed. The new behaviour is triggered
by adding a link for this previously unsupported VLAN.

The untagged mapping was chosen initially to support the
assumed most common use case: Most current MBIM devices only
support a single IP session (i.e. session 0 only), and using
untagged frames lets the users completely ignore the
additonal complexity of the multiplexing layer.

But when the multiplexing features of MBIM are used, then
this netdev gets a double meaning: It becomes the master
interface for all the VLAN subdevs the additional sessions
are mapped to, while still serving as the untagged IP
interface for session 0.

This can be problematic, especially when using Device Service
Streams (DSS), as have become apparent recently with the
availability of devices with real DSS support. Some use cases
need to e.g set a MTU which is higher than allowed for IP
Session 0. The dual role also leads to the situation where
the IP Session 0 interface cannot be taken down without
breaking unrelated IP or DSS sessions - a devastating side
effect which applications managing a simple IP session cannot
be expected to be aware of. A typical DHCP client will assume
that it should bring the interface down after releasing the
IP lease.

These problems can be avoided by tagging IP session 0 packets
too, making this session similar to all other multiplexed
sessions. This redefines the main netdev as an upper master
interface only.

Dave Miller mentioned he'd like to see SET_ETHTOOL_OPS gone.

	drivers/net/ethernet/altera/altera_sgdma.c
	net/netlink/af_netlink.c

The netlink conflict dealt with moving to netlink_capable() and
netlink_ns_capable() in the 'net' tree vs. supporting 'tc' operations
in non-init namespaces.  These were simple transformations from
netlink_capable to netlink_ns_capable.

The Altera driver conflict was simply code removal overlapping some
void pointer cast cleanups in net-next.

in the option's entry) are removed, the ones that explained important
points about the setting function have been moved above the respective
set function in bond_options.c

59993f48b3 Revert "net: eth: cpsw: Correctly attach to GPIO bitbang MDIO driver"
This reverts commit f8d56d8f892be43a2404356073e16401eb5a42e6 ("net:
 eth: cpsw: Correctly attach to GPIO bitbang MDIO driver").

Fix potential null-pointer dereference at probe if the mdio-gpio device
has not been successfully probed yet.

The offending commit is plain wrong for a number of reasons. First of
all it accesses internal driver data of an unrelated device. Neither
does it check that the data is non-null (which it is in case the device
has not been probed yet).

Furthermore, the decision on whether to treat any driver data according
to the mdio-gpio driver's internals is made based on the node name. But
the name is not compared against "mdio" which is the normal name for the
node, but rather against "gpio" which the node does not have to be named
(and shouldn't be according to the binding documentation). [ If this
hack is to be kept out-of-tree it should at least be matching against
the compatible property. ]

This driver maps 802.1q VLANs to MBIM sessions. The mapping is based on
a bogus assumption that all tagged frames will use the acceleration API
because we enable NETIF_F_HW_VLAN_CTAG_TX. This fails for e.g. frames
tagged in userspace using packet sockets. Such frames will erroneously
be considered as untagged and silently dropped based on not being IP.

Fix by falling back to looking into the ethernet header for a tag if no
accelerated tag was found.

6af55ff52b Driver for Beckhoff CX5020 EtherCAT master module.
This driver adds support for EtherCAT master module located on CCAT
FPGA found on Beckhoff CX series industrial PCs. The driver exposes
EtherCAT master as an ethernet interface.

EtherCAT is a fieldbus protocol defined on top of ethernet and Beckhoff
CX5020 PCs come with built-in EtherCAT master module located on a FPGA,
which in turn is connected to a PCI bus.

f398a77177 qlcnic: Fix Kconfig dependency on HWMON
Commit 1f0f467b670e "qlcnic: Add hwmon interface to export board
temperature" introduced a randconfig build error in the case
when the hwmon framework is built as a module and the qlcnic
driver itself is built-in:

drivers/built-in.o: In function `qlcnic_register_hwmon_dev':
drivers/net/ethernet/qlogic/qlcnic/qlcnic_sysfs.c:1301:
undefined reference to `hwmon_device_register_with_groups'
drivers/built-in.o: In function `qlcnic_unregister_hwmon_dev':
drivers/net/ethernet/qlogic/qlcnic/qlcnic_sysfs.c:1309:
undefined reference to `hwmon_device_unregister'.

This changes the Kconfig logic to enforce that the qlcnic hwmon
support can only be enabled if it is possible to successfully
build it.

84d7ad2c3b qlcnic: Set real_num_{tx|rx}_queues properly
Do not set netdev->real_num_tx_queues directly,
let netif_set_real_num_tx_queues() take care of it.
Do not overwrite netdev->num_tx_queues everytime when driver
changes its Tx ring size through ethtool -L and also notify
stack to update number of Rx queues.

d5d2bf3eab qlcnic: Fix panic while dumping TX queues on TX timeout
o In case of non-multi TX queue mode driver does not initialize "crb_intr_mask" pointer
  and driver was accessing that un-initialized pointer while dumping TX queue.
  So dump "crb_intr_mask" only when it is initilaized.

76a691d0ab jme: Fix DMA unmap warning
The jme driver forgot to check the return status from pci_map_page in its tx
path, causing a dma api warning on unmap.  Easy fix, just do the check and
augment the tx path to tell the stack that the driver is busy so we re-queue the
frame.

528b971bba w83977af_ir: remove two faux Kconfig macros
Ever since v2.3.5 the driver for "Winbond W83977AF (IR)" contains two
unneeded preprocessor macros.

CONFIG_NETWINDER_TX_DMA_PROBLEMS is never defined and can safely be
removed. And CONFIG_NETWINDER_RX_DMA_PROBLEMS is just an alias for
CONFIG_ARCH_NETWINDER, so that (valid) Kconfig macro can be used
instead.
