9b0467ed9a wilc1000: remove redundant assignment to pointer vif 
The assignment to pointer vif is redundant as the assigned value
is never read, hence it can be removed.

339754ffdb wilc1000: added queue support for WMM 
Added multiple queues[BK,BE,VI,VO] to handle different priority data
packets. Before adding a packet to the queue, checked its priority from
the header, and then add to the suitable queue. The limit for each queue
is maintained separately. Also while passing the packets to the firmware
via VMM take care to select data packets based on priority and available
space.

55bd149978 net: wilc1000: clean up resource in error path of init mon interface 
The wilc_wfi_init_mon_int() forgets to clean up resource when
register_netdevice() failed. Add the missed call to fix it.
And the return value of netdev_priv can't be NULL, so remove
the unnecessary error handling.

cce0e08301 wilc1000: let wilc_mac_xmit() return NETDEV_TX_OK 
The method ndo_start_xmit() is defined as returning an 'netdev_tx_t',
which is a typedef for an enum type defining 'NETDEV_TX_OK' but this
driver returns '0' instead of 'NETDEV_TX_OK'.

Fix this by returning 'NETDEV_TX_OK' instead of '0'.

5625f965d7 wilc1000: move wilc driver out of staging 
WILC1000 is an IEEE 802.11 b/g/n IoT link controller module. The
WILC1000 connects to Microchip AVR/SMART MCUs, SMART MPUs, and other
processors with minimal resource requirements with a simple
SPI/SDIO-to-Wi-Fi interface.

WILC1000 driver has been part of staging for few years. With
contributions from the community, it has improved significantly. Full
driver review has helped in achieving the current state.
The details for those reviews are captured in 1 & 2.
