32 * device_xmit - asynchrous data tx function
33 * device_set_multi - set mac filter
34 * device_ioctl - ioctl entry
35 * device_close - shutdown mac/bbp & free dma/descripter resource
36 * device_alloc_frag_buf - rx fragement pre-allocated function
37 * device_free_tx_bufs - free tx buffer function
38 * device_dma0_tx_80211- tx 802.11 frame via dma0
39 * device_dma0_xmit- tx PS bufferred frame via dma0
40 * device_init_registers- initial MAC & BBP & RF internal registers.
41 * device_init_rings- initial tx/rx ring buffer
42 * device_init_defrag_cb- initial & allocate de-fragement buffer.
43 * device_tx_srv- tx interrupt service function
