alloc_etherdev_mqs - Allocates and sets up an Ethernet device

struct net_device * alloc_etherdev_mqs(int  sizeof_priv , unsigned int  txqs , unsigned int  rxqs );

sizeof_priv
    Size of additional driver-private structure to be allocated for this Ethernet device

txqs
    The number of TX queues this device has.

rxqs
    The number of RX queues this device has.

Fill in the fields of the device structure with Ethernet-generic values. Basically does everything except registering the device.
