[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).
