ax8817x_unbind does not free the interrupt URB after unlinking.

Noticed that the net->status already has a flag for link so my
private structure variable for link was redundant.  Worked around
this and was able to kill off the unique ax8817x_get_link() function
in the process.

This patch uses the interrupt URB on the ax8817x for link detection.
This allows the driver to notify userspace when link drops/comes back
so it can take action such as run dhclient, etc.

I was also able to reduce the bind function by using some of the stock
mii_xxx calls as well as my own for handling initial link negotiation.

Add support for Buffalo's LUA-U2-KTX, which is a AX8817X based usb

If the string descriptor fetch works, no problem.  Else
make the disconnect() logic -- newly called because of
"recent" changes to interface claiming logic -- use its
fast cleanup path, since we're still not fully set up yet.

Should resolve OSDL bugid 2714; please merge.

From: Jeff Garzik

	Jeff's patch adds a helper for obtaining mii_ioctl_data from ifreq
and switches drivers to it.  It's almost a "move common expression into
inline helper", except that instead of

	(struct mii_ioctl_data *)&rq->ifr_ifru.ifru_data

it does

	(struct mii_ioctl_data *)&rq->ifr_ifru

- pointer to union instead of pointer to a field of union that has nothing
to do with mii_ioctl_data *and* adds confusion by being a pointer itself.

This patch should help correct the "missing diagnostics with
CONFIG_USB_DEBUG during CDC Ethernet probe()" issue.  Some
folk are having problems with firmware that doesn't respond
properly to descriptor fetches -- which is unnecessarily
confusing because the diagnostics aren't being printed.

Thanks to Tridge's findstatic.pl script for helping find these.

This adds another ax8817x device to "usbnet".

The only driver under usb/net that needed any altsetting changes was
usbnet.  I'm not looking forward to going through all the source files
under usb/serial. :-(

Handle some PL-2301/2302 devices better.

Some hardware had the poor taste to misbehave during probe(),
which turned up a minor bug.  This fixes it:  don't try to
free a network device that hasn't been registerd.

Some of the 480 Mbit/sec USB host-to-host links have ALI
chips in them.  They seem to work with no problem, given
this patch, even when the ends talk different speed.

New Zaurus ID, from Sven Trampel <Sven.Trampel@surf-club.de>

[USB] usbnet updates:  new devices, cleanups

New devices:  Aten UC210T, Zaurus SL-6000

Cleanup, factoring out shared CDC glue for Ethernet, Zaurus,
and eventually RNDIS.

Re-diffed against the usb-2.6-devel tree.

Remaining kfree -> free_netdev replacements (easy part of free_netdev() fixes)

This patch adds definitions:

  - New "video" class, for video cameras and more complicated devices;

  - New "Interface association" descriptor type, used by video class,
    along with two other assigned desciptor type codes (OTG, "debug")
    listed in the same ECN to the USB 2.0 spec;

  - Type declarations for "Interface association" and OTG descriptors.

It also replaces three copies of USB_DT_CS_* declarations in audio
support with one in <linux/usb_ch9.h>, and uses the newly exposed
symbol in "usbnet".  (Near as I can tell, the convention for those
"class specific" descriptor types started with audio, and was then
adopted by several other class specifications.)

The dma hooks whereby EHCI can pass 64bit DMA support
up the driver stack (to avoid buffer copies) turn out
to broken on most architectures(*).  This patch just
disables them all, since it looks like those mechanisms
won't get fixed before 2.6.0-final.  For now it'd only
matter on a few big Intel boxes anyway.

Please merge.

(*) On x86, mips, and arm dma_supported() doesn't
     even compare with the device's mask.  On several
     other architectures (reported on ppc, alpha,
     and sparc64), asking that question for non-PCI
     devices will just BUG() -- even though all info
     needed to answer the question is right at hand.

* Provide operational link testing via ethtool
* Provide get/set features via ethtool.

* ax8817x_set_multicast - use address of dev->data, not contents
* ax8817x_write_async_cmd - free request and urb if submit fails

This is a resend of all of my recent usbnet additions which
center on adding ethtool_ops support.  All have been re-diffed
against the latest usbnet from BK.

Changes:
* Add ethtool_ops support to usbnet
* Add GPIO bit toggling upon initialization of ax8817x devices
  so that xmit works properly
* Add Wake-On-Lan and eeprom dump support for ax8817x devices
  (this only adds the config support for WOL, actual operation
   is more of a USB/Power Management function)
* Change ax8817x_set_multicast to not kmalloc for the filter
  since there was no clean way to free the memory after URB submit.
  Instead, we make use of the 20 byte dev->data.

This patch fixes usbnet and usbtest.  When checking endpoints, they
iterate through all interfaces out to intf->max_altsetting, but they
should only go up to intf->num_altsetting.  The max_altsetting value
refers to the amount of space _allocated_ for usb_host_interface
structures, not the number that are really in use.

This makes the new CDC Ethernet code handle more devices:

  - Uses the active config, not just the default one, if it's
    coping "descriptors in wrong place" quirk.  (bugfix)

  - Uses usb_ifnum_to_if() to get interfaces.  (bugfix)

  - AMBIT USB cable modems have bogus CDC Union descriptors;
    workaround by switching master and slave.  (add quirk)

  - To make it easier the next time we run into firmware
    that violates the class spec, add debug messages saying
    exactly why it's giving up on a given CDC device.

Net result, this code now handles at least one more
cable modem design.

This goes on top of Dave Hollis' patch, and makes the front matter
match the slightly revised role -- and mention that new support.
It also eliminates a potentially confusing name and corrects an
omission (Zaurus framing wasn't printed).

This patch adds support to usbnet for devices based on the ASIX AX88172
USB 2.0 Ethernet chipset.

A trailing else in the #ifdef CONFIG_USB_NET1080 block that would
prevent it from properly filling the bulk URB.

this can oops.

  - check for mem alloc failure

  - fail if second interface is already claimed

Turns out that when PM is in use, some D3cold resume paths
could have one thread, holding the network lock, deadlock
in flush_scheduled_work() since an event task is waiting
for that same lock.  Fix is to call that later, when the
lock isn't held.

This patch:

   - Makes the cdc code handle a Motorola cable modem that stores
     CDC descriptors in the wrong place.  The workaround might be
     helpful for other hardware too.  (This was a 2.4 regression.)

   - Recognizes another Zaurus (PXA 255 based clamshell, not yet
     sold by Sharp in the US).

   - Cleaned the Zaurus stuff up a bit.  Rather than expecting
     a new driver_info struct (or re-using the right one) for
     each new pxa based product, they all use the same one.  So
     patches for new products only need new usb_device_id entries.
     (Also notes the issue that every Zaurus model will need to be
     blacklisted for CDC if the Z code isn't enabled.)
