[PATCH 2.6.10-rc1 14/15] wireless/orinoco: add minimal ethtool support

[Dan Williams <dcbw@redhat.com>]

Update in-kernel orinoco wireless drivers to upstream CVS.
None of this is original code by Dan Williams, simply a
broken down patch set split-out from upstream orinoco CVS.

o Add minimal ethtool support (Pavel Roskin)
