From: Ursula Braun-Krahl From: Frank Pavlic From: Thomas Spatzier From: Peter Tiedemann 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.
