This patch fixes the register offset used for super-speed connection's
max packet size. Without it using the 338x series of devices in enhanced
mode will only allow full or high speed operation to function correctly.

Remove fiforegs from struct net2280 and net2280_ep as it is unused.
By the way, ep->fiforegs = &dev->fiforegs[i] assignment is incorrect.
It should be ep->fiforegs = &dev->fiforegs[ne[i]], but it doesn't
matter now.

This patch adds support for the PLX USB3380 and USB3382.

This driver is based on the driver from the manufacturer.

Since USB338X is register compatible with NET2280, I thought that it
would be better to include this hardware into net2280 driver.

Manufacturer's driver only supported the USB33X, did not follow the
Kernel Style and contain some trivial errors. This patch has tried to
address this issues.

This patch has only been tested on USB338x hardware, but the merge has
been done trying to not affect the behaviour of NET2280.

We want to use WARN() as a variant of WARN_ON(), however a few drivers are
using WARN() internally.  This patch renames these to WARNING() to avoid the
namespace clash.  A few cases were defining but not using the thing, for those
cases I just deleted the definition.

The net2280 driver is too eager to send zero-length packets when
IN tokens are received on ep0.  No such packet should be sent (the
driver should NAK) before the gadget driver has queued the proper
response.  Otherwise deferred responses are impossible.

This patch (as823) makes net2280 avoid sending ZLPs for IN transfers
on ep0 until a response has been submitted, and avoids stalling when an
OUT packet is received before a request has been submitted for an OUT
transfer on ep0.

Below is a patch to gadgets/net2280.[ch] which adds support for the
net2282 controller. The original code was kindly provided by PLX
Technology, I just merged it with the current net2280 driver in the
kernel. Tested on 2.6.15.6, but only with 2282. I did the merge, so
that the behaviour for the 2280 is unaffected (except for short delays
for extra checks).

Support for net2282 in net2280 driver.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
