• Initializes/de-initializes the module during insert/remove
• Registers Interrupt Service Register (ISR)
• Turns on and turns off the chip by controlling the CHIP_EN and RESET_N GPIOs
• Registers the net_device interface
• Downloads and starts the firmware
• Implements the following net_device operations:
  • mac_init_fn
  • wilc_mac_open
  • wilc_mac_close
  • wilc_mac_xmit
  • mac_stats
  • wilc_set_multicast_list
  • wilc_set_mac_addr
• Pushes TX packets into the TX queue
• Delivers RX packets to the Linux stack
