[2/5] Orinoco merge updates, part the fourth: ignore_disconnect flag

[David Gibson <david@gibson.dropbear.id.au>]

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).
