The LG-VL600 LTE USB modem supports IPv6, but uses and expects an IPv4
ethertype (0x800) for these packets instead of the standard 0x86dd.
This patch peeks at the IP version in the L3 header and sets the
ethertype appropriately for IPv6 packets.

Fix a misusage of the struct usb_cdc_notification to pass arguments to the
usb_control_msg function.  The usb_control_msg function expects host endian
arguments but usb_cdc_notification stores these values as little endian.

Now usb_control_msg is directly invoked with host endian values.

The AX88772B uses only 11 bits of the header for the actual size. The other bits
are used for something else. This causes dmesg full of messages:

This patch trims the check to only 11 bits. I believe on older chips, the

Remove linux/mm.h inclusion from netdevice.h -- it's unused (I've checked manually).

To prevent mm.h inclusion via other channels also extract "enum dma_data_direction"
definition into separate header. This tiny piece is what gluing netdevice.h with mm.h
via "netdevice.h => dmaengine.h => dma-mapping.h => scatterlist.h => mm.h".
Removal of mm.h from scatterlist.h was tried and was found not feasible
on most archs, so the link was cutoff earlier.

Hope people are OK with tiny include file.

Note, that mm_types.h is still dragged in, but it is a separate story.

Introducing driver for the network port of Samsung Kalmia based USB LTE modems.
It has also an ACM interface that previous patches associates with the "option"
module. To access those interfaces, the modem must first be switched from modem
mode using a tool like usb_modeswitch.

As the proprietary protocol has been discovered by watching the MS Windows driver
behavior, there might be errors in the protocol handling, but stable and fast
connection has been established for hours with Norwegian operator NetCom that
distributes this modem with their LTE/4G subscription.

More and updated information about how to use this driver is available here:

The USB protocol this driver implements appears to require 2 bytes of
padding in front of each received packet.  This used to be equal to
the value of NET_IP_ALIGN on x86, so the driver abused that constant
and mostly worked, but this is no longer the case.  The driver also
mixed up the URB and packet lengths, resulting in 2 bytes of junk at
the end of the skb.

Introduce a private constant for the 2 bytes of padding; fix this
confusion and check for the under-length case.

This patch makes use of the EVENT_DEV_OPEN flag introduced recently to
fix one out of memory issue, which can be reproduced on omap3/4 based
pandaboard/beagle XM easily with steps below:

	- enable runtime pm
	echo auto > /sys/devices/platform/usbhs-omap.0/ehci-omap.0/usb1/1-1/1-1.1/power/control

	- ifconfig eth0 up

	- then out of memroy happened, see [1] for kernel message.

Follows my analysis:
	- 'ifconfig eth0 up' brings eth0 out of suspend, and usbnet_resume
	is called to schedule dev->bh, then rx urbs are submited to prepare for
	recieving data;

	- some usbnet devices will produce garbage rx packets flood if
	info->reset is not called in usbnet_open.

	- so there is no enough chances for usbnet_bh to handle and release
	recieved skb buffers since many rx interrupts consumes cpu, so out of memory
	for atomic allocation in rx_submit happened.

This patch fixes the issue by simply not allowing schedule of usbnet_bh until device
is opened.

This updates the network drivers so that they don't access the
ethtool_cmd::speed field directly, but use ethtool_cmd_speed()
instead.

For most of the drivers, these changes are purely cosmetic and don't
fix any problem, such as for those 1GbE/10GbE drivers that indirectly
call their own ethtool get_settings()/mii_ethtool_gset(). The changes
are meant to enforce code consistency and provide robustness with
future larger throughputs, at the expense of a few CPU cycles for each
ethtool operation.

All drivers compiled with make allyesconfig ion x86_64 have been
updated.

This makes sure that when a driver calls the ethtool's
get/set_settings() callback of another driver, the data passed to it
is clean. This guarantees that speed_hi will be zeroed correctly if
the called callback doesn't explicitely set it: we are sure we don't
get a corrupted speed from the underlying driver. We also take care of
setting the cmd field appropriately (ETHTOOL_GSET/SSET).

This applies to dev_ethtool_get_settings(), which now makes sure it
sets up that ethtool command parameter correctly before passing it to
drivers. This also means that whoever calls dev_ethtool_get_settings()
does not have to clean the ethtool command parameter. This function
also becomes an exported symbol instead of an inline.

All drivers visible to make allyesconfig under x86_64 have been
updated.

Resubmit interrupt URB if device is open.  Use a flag set in

The default maximum transmit length for NCM USB frames should be so
that a short packet happens at the end if the device supports a length
greater than the defined maximum. This is achieved by adding 4 bytes
to the maximum length so that the existing logic can fit a short
packet there.

Some RNDIS devices don't respond on the control channel until polled
on the status channel.  In particular, this was reported to be the
case for the 2Wire HomePortal 1000SW and for some Windows Mobile
devices.

This is roughly based on a patch by John Carr <john.carr@unrouted.co.uk>
which is currently applied by Mandriva.

There's a race (not fixed here) in smsc75xx in setting RFE_CTL that's not
properly handled via rfe_ctl_lock. Spinlock is not a good tool here, as
this has to wait for URB completion (or maybe just submission) after issuing
register write request. Otherwise, the rfe_ctl might be changed just after
spin_unlock() and device left programmed with other value.

smsc95xx has increased hard_header_len for the case of TX checksumming.

smsc75xx is fixed to advertise IP+IPV6_CSUM instead of HW_CSUM as it does
not use csum_start/csum_offset.

The documentation for the USB ethernet devices suggests that
only some devices are supposed to use usb0 as the network interface
name instead of eth0. The logic used there, and documented in
Kconfig for CDC is that eth0 will be used when the mac address
is a globally assigned one, but usb0 is used for the locally
managed range that is typically used on point-to-point links.

Unfortunately, this has caused a lot of pain on the smsc95xx
device that is used on the popular pandaboard without an
EEPROM to store the MAC address, which causes the driver to
call random_ether_address().

Obviously, there should be a proper MAC addressed assigned to
the device, and discussions are ongoing about how to solve
this, but this patch at least makes sure that the default
interface naming gets a little saner and matches what the
user can expect based on the documentation, including for
new devices.

The approach taken here is to flag whether a device might be a
point-to-point link with the new FLAG_POINTTOPOINT setting in
the usbnet driver_info. A driver can set both FLAG_POINTTOPOINT
and FLAG_ETHER if it is not sure (e.g. cdc_ether), or just one
of the two.  The usbnet framework only looks at the MAC address
for device naming if both flags are set, otherwise it trusts the
flag.
