// Revision History:
//
// Date         
//---------------------------------------------------------------------------
// 10/10/00     jbeaujon    -changed vendor name in OID_GEN_VENDOR_DESCRIPTION
//                           from "Aironet" to "Cisco".
// 
// 10/20/00     jbeaujon    -added the following query OIDs:
//                              OID_802_11_SSID
//                              OID_802_11_INFRASTRUCTURE_MODE
//                              OID_802_11_BSSID
//                          -added the following set OIDs:
//                              OID_802_11_SSID
//                              OID_802_11_INFRASTRUCTURE_MODE
//                              OID_802_11_DISASSOCIATE
//                              OID_802_11_AUTHENTICATION_MODE
// 
// 03/26/01     jbeaujon    -added OID_802_11_RELOAD_DEFAULTS
//
// 05/04/01     spb001      -Added "fast" initialization option.  By changing
//                           the InitFW() to only reset the device on the 
//                           first call.  InitFW1() must then be called to 
//                           finish the initialization. Subsequent calls to InitFW()
//                           will work as prior to changes.
//
// 05/10/01     spb004      -Work around for network card not sending an updatelinkstatus
//                           interrupt when it should
//
// 05/31/01     spb008      -Make sure we don't update link status when we are flashing
//
// 06/05/01     spb009      -Make sure we only use the botton byte of the signal
//                           strength as an index into the dbmTable (only 256 bytes).
//
// 06/12/01     spb010      -If we are using the fast init option, then 
//                           we don't want to init interrupts yet because firm
//                           ware will zero out the interrupt enable
//                           register during the reset.  This caused a race 
//                           condition where the card would be up and running
//                           but not interrupts were enabled.
//
// 06/19/01     spb012      -Hack to stop jerkiness when in PSP.   This needs
//                           to really be done on either a per oid basis or
//                           better yet, at a lower level i.e. per command.
//
// 06/28/01     spb014      -Fixed MiniportQuery NDIS_802_11_SSID so that
//                           we will return the currently associated SSID.
//
// 07/03/01     spb017      -Added counter to cancel timer so we don't hang 
//                           in destructor forever.
//
// 07/10/01     spb018      -If you are using the Home configuration, and WZC
//                           plumbs down a WEP key, turn off Home configuration
//                           because otherwise the new WEP key won't be used
//                           since HOME key is 5 and 802_11 spec only has 1-4.
//
// 07/23/01     spb026      -Changed OID_QUERY_RADIO_STATE in oidx500.cpp since
//                           there was no reason to access the card it is ok
//                           now to check when flashing
//
// 08/01/01     spb027      -Added ability to cancel flash timer if we are NDIS5
//                           driver.
//
// 08/03/01     spb029      -Added length check to ssid query
//
// 08/13/01     raf         -Magic Packet fixes
