| * 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 - asynchronous data tx function |
| * device_set_multi - set mac filter |
| * device_ioctl - ioctl entry |
| * device_close - shutdown mac/bbp & free dma/descriptor 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 buffered 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 |
