The latest kernel added a pretty ugly fix for the orinoco etherleak bug
which contains bogus skb->len checks already done by the caller and causes
copies of all odd sized frames (which are quite common)
While the skb->len check should be ripped out the other fix is harder to do
properly so I'm proposing for this the -mm tree only until next 2.6.x so
that it gets tested.
Instead of copying buffers around blindly this code implements a padding
aware version of the hermes buffer writing function which does padding as
the buffer is loaded and thus more cleanly and without bogus 1.5K copies.

The orinoco driver can send uninitialized data exposing random pieces of
the system memory. This happens because data is not padded with zeroes
when its length needs to be increased.

Latest wireless extensions moved a field from netdev -> wireless_handlers.
The WE core will now printk a warning on every call to get_wireless_stats()
on a driver that still uses the old field. This patch fixes orinoco.

Remove inneeded system includes.
Most system includes are not needed. In particular, the hardware
backends don't need anything network related. Some includes have been
moved from local headers to the C files where they are actually used.
Includes that have to be in the local headers are no longer from the C
sources.

If the frame has ToDS flag set, mark it by setting skb->pkt_type to
PACKET_OTHERHOST, so that applications unaware of promiscous mode won't get
uplink (STA->AP) packets for STA->STA transmissions relayed by the AP.
Thanks to John Denker and David Gibson for finding the problem and the
solution.

Don't attempt to manually set the channel in infrastructure mode, the

Adds an ignore_disconnect module parameter. When enabled, the driver
will continue attempting to send packets even when the firmware has
told us we've lost our link to the AP. On some firmwares this
substantially increases the usable range of the card (presumably
because we have an interrmittent connection, but the firmware is able
to queue the packets for us until we're connected again). On some
other cards, it causes the firmware to fall in a screaming heap :(
(hence, default off).

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!
