    [patch 1/2] s390: lcs performance enhancements
    
    From: Klaus Wacker <kdwacker@de.ibm.com>
    	- When flood pinging (with large packet size) an LCS device,
    	  about 90 % of all packets are dropped by driver.
    	- increased number of lcs IO buffers to 32.
    	- use netif_stop_queue/netif_wake_queue in lcs_start_xmit routine
    	- don't lock the whole xmit routine but just the piece of code where
    	  tx_buffer is touched.
