[PATCH] s390: network driver changes 

From: Ursula Braun-Krahl <braunu@de.ibm.com>
From: Frank Pavlic <pavlic@de.ibm.com>
From: Thomas Spatzier <tspat@de.ibm.com>
From: Peter Tiedemann <ptiedem@de.ibm.com>

s390 network driver changes:
 - ctc: replace snprintf by strlcpy.
 - lcs: change info text for lcs cards from "OSA2 card" to "OSA LCS card".
 - lcs: fix alignment of lcs_cmd structure to get multicast pings working.
 - lcs: first call in_dev_put then register multicast addresses.
 - netiucv: remove unused device timer and unused flags field.
 - netiucv: include interrupt type in pathid mismatch message.
 - qeth: don't start a new kernel thread for every new ip address.
 - qeth: fix IP assist command sequence numbers.
