David Brownell 0aa599c564 [PATCH] USB: usbnet (6/9) module for Zaurii and compatibles
This moves usbnet support for Zaurus and compatibles into its own module.
Other than exporting a couple of helper functions, this just involved
shuffling some code and updating the comments.

David Brownell 2e55cc7210 [PATCH] USB: usbnet (3/9) module for ASIX Ethernet adapters
This patch moves the ASIX AX8817x driver into its own file, just using
the "usbnet" infrastructure as a utility library.

 - As with "cdc_subset" this involved minor Kconfig/kbuild tweaks,
   moving code from one file to another, and exporting a few functions.

 - This includes updates from Jamie Painter to add (and use) a new hook
   to handle the different maximum transfer sizes for rx and tx sides.

 - Also from Jamie, some bugfixes:
    * MDIO byteorder (to address some PPC media negotiation problems);
    * Force alignment at key spots when using ax88772 framing (on some
      embedded hardware, the network stack will break otherwise);
    * Address some link reset problems.

It also makes this driver use the standard (5 seconds vs half second)
control timeouts used elsewhere in USB; and wraps a few lines before
the 80th column (which previously needed it).

David Brownell 38bde1d469 [PATCH] USB: usbnet (2/9) module for simple network links
This patch creates the first of several separate "minidriver" modules
for "usbnet".  This one handles only the very simplest hardware, which
can be handled almost entirely by the "usbnet" core.

    - Move device-specific bits into new "cdc_subset.c" driver,
      shrinking "usbnet" by a bunch;

    - Export the functions needed to support this minidriver
      (with EXPORT_SYMBOL_GPL);

    - Update Kconfig and kbuild accordingly.

This one handles about a dozen different device types, with the most
notable ones being Gumstix and most Linux-based PDAs (except Zaurus
running that ancient code from Sharp).

David Brownell f29fc25997 [PATCH] USB: usbnet (1/9) clean up framing
This starts to prepare the core of "usbnet" to know less about various
framing protocols that map Ethernet packets onto USB, so "minidrivers"
can be modules that just plug into the core.

  - Remove some framing-specific code that cluttered the core:

      * net->hard_header_len records how much space to preallocate;
        now drivers that add their own framing (Net1080, GeneLink,
	Zaurus, and RNDIS) will have smoother TX paths.  Even for
	the drivers (Zaurus, Net1080) that need trailers.

      * defines new dev->hard_mtu, using this "hardware" limit to
        check changes to the link's settable "software" mtu.

      * now net->hard_header_len and dev->hard_mtu are set up in the
        driver bind() routines, if needed.

  - Transaction ID is no longer specific to the Net1080 framing;
    RNDIS needs one too.

  - Creates a new "usbnet.h" header with declarations that are shared
    between the core and what will be separate modules.

  - Plus a couple other minor tweaks, like recognizing -ESHUTDOWN
    means the keventd work should just shut itself down asap.

The core code is only about 1/3 of this large file.  Splitting out the
minidrivers into separate modules (e.g. ones for ASIX adapters,
Zaurii and similar, CDC Ethernet, etc), in later patches, will
improve maintainability and shrink typical runtime footprints.
