* File: main_usb.c
*
* Purpose: driver entry for initial, open, close, tx and rx.
*
* Author: Lyndon Chen
*
* Date: Dec 8, 2005
*
* Functions:
*
* vt6656_probe - module initial (insmod) driver entry
* device_remove1 - module remove entry
* device_open - allocate dma/descripter resource & initial mac/bbp function
* device_xmit - asynchrous data tx function
* device_set_multi - set mac filter
* device_ioctl - ioctl entry
* device_close - shutdown mac/bbp & free dma/descripter resource
* device_alloc_frag_buf - rx fragement pre-allocated function
* device_free_tx_bufs - free tx buffer function
* device_dma0_tx_80211- tx 802.11 frame via dma0
* device_dma0_xmit- tx PS bufferred frame via dma0
* device_init_registers- initial MAC & BBP & RF internal registers.
* device_init_rings- initial tx/rx ring buffer
* device_init_defrag_cb- initial & allocate de-fragement buffer.
* device_tx_srv- tx interrupt service function
