Warner Losh 53e655ce37 Check in the known good version of the wi driver, with prism/symbol 
support stripped out and minimally renamed to owi.  This driver
attaches to lucent cards only.  This is designed to aid in the testing
of fixes to the wi driver for lucent cards.  It is supported only as a
module (you cannot compile it into your kernel).  You cannot have the
wi driver in your kernel (or loaded as a moudle) to use the owi
module.

I've not connected it to build, as this module is currently for
debugging purposes.  This is for developers only at the present time.
If we can't get lucent support fixed by 5.2 code freeze, then we'll
re-evaulate this support level.  Please use this to fix the lucent
support in dev/wi.  This will be removed from the system when lucent
support has been fixed in dev/wi.

Note to developers: Do not connect this to the build, make it possible
to build into the kernel or otherwise 'integrate' this into system
without checking with me first.  This is for debugging purposes only.

If this doesn't work for you, I don't want to hear about it unless you
are fixing the wi driver :-)

/*
* The WaveLAN/IEEE cards contain an 802.11 MAC controller which Lucent
* calls 'Hermes.' In typical fashion, getting documentation about this
* controller is about as easy as squeezing blood from a stone. Here
* is more or less what I know:
*
* - The Hermes controller is firmware driven, and the host interacts
* with the Hermes via a firmware interface, which can change.
*
* - The Hermes is described in a document called: "Hermes Firmware
* WaveLAN/IEEE Station Functions," document #010245, which of course
* Lucent will not release without an NDA.
*
* - Lucent has created a library called HCF (Hardware Control Functions)
* though which it wants developers to interact with the card. The HCF
* is needlessly complex, ill conceived and badly documented. Actually,
* the comments in the HCP code itself aren't bad, but the publically
* available manual that comes with it is awful, probably due largely to
* the fact that it has been emasculated in order to hide information
* that Lucent wants to keep proprietary. The purpose of the HCF seems
* to be to insulate the driver programmer from the Hermes itself so that
* Lucent has an excuse not to release programming in for it.
*
* - Lucent only makes available documentation and code for 'HCF Light'
* which is a stripped down version of HCF with certain features not
* implemented, most notably support for 802.11 frames.
*
* - The HCF code which I have seen blows goats. Whoever decided to
* use a 132 column format should be shot.
*
* Rather than actually use the Lucent HCF library, I have stripped all
* the useful information from it and used it to create a driver in the
* usual BSD form. Note: I don't want to hear anybody whining about the
* fact that the Lucent code is GPLed and mine isn't. I did not actually
* put any of Lucent's code in this driver: I only used it as a reference
* to obtain information about the underlying hardware. The Hermes
* programming interface is not GPLed, so bite me.
