  * Purpose: Handles the Basic Service Set & Node Database functions
  *
  * Functions:
- *      BSSpSearchBSSList - Search known BSS list for Desire SSID or BSSID
- *      BSSvClearBSSList - Clear BSS List
- *      BSSbInsertToBSSList - Insert a BSS set into known BSS list
- *      BSSbUpdateToBSSList - Update BSS set in known BSS list
- *      BSSbIsSTAInNodeDB - Search Node DB table to find the index of matched DstAddr
- *      BSSvCreateOneNode - Allocate an Node for Node DB
- *      BSSvUpdateAPNode - Update AP Node content in Index 0 of KnownNodeDB
- *      BSSvSecondCallBack - One second timer callback function to update Node DB info & AP link status
- *      BSSvUpdateNodeTxCounter - Update Tx attemps, Tx failure counter in Node DB for auto-fall back rate control
