beceem: support multiple queues

Current kernels have multi-queue support which can be used by
this device. This has the advantage that a single type of traffic
will not block other types.

-* Function    -	bcm_transmit()
-*
-* Description - This is the main transmit function for our virtual
-*				interface(eth0). It handles the ARP packets. It
-*				clones this packet and then Queue it to a suitable
-* 		 		Queue. Then calls the transmit_packet().
-*
-* Parameter   -	 skb - Pointer to the socket buffer structure
-*				 dev - Pointer to the virtual net device structure
-*
-* Returns     -	 zero (success) or -ve value (failure)
