This driver is for a number of different Option devices.  Originally
written by Option and Andrew Bird, but cleaned up massivly for
acceptance into mainline by me and others.

Many thanks to the following for their help in cleaning up the driver by
providing feedback and patches to it:

Some devices running some WinCE firmware (with SC_* Samsung processors
according to the SynCE project, verified on a HTC P3600 device) fail to
register because they apparently need extra time to respond correctly to
requests.  Increase the existing delay to satisfy them.  Based on code
from the SynCE project, on a suggestion of David Brownell.

This patch Works For Me(tm).

None of these files use any of the functionality promised by

The asix usb driver currently depends on NET_ETHERNET which means you
cannot enable this driver if you only have 1000mbit enabled in your kernel.
Since there is no real dependency between the NET_ETHERNET portion and the
asix driver, simply drop it.

When query for OID_GEN_PHYSICAL_MEDIUM fails, uninitialized pointer

Patch fixes phym to be initialized and setup correctly when

This patch should resolve a problem that's troubled support for
some RNDIS peripherals.  It seems to have boiled down to using a
variable to establish transfer size limits before it was assigned,
which caused those devices to fallback to a default "jumbogram"
mode we don't support.  Fix by assigning it earlier for RNDIS.

* Fixed a leak in ax88172_bind() - on success it forgot to kfree() the
