[PATCH] s390: network driver 

From: Martin Schwidefsky <schwidefsky@de.ibm.com>

Network driver changes:
 - ctc: Add missing irb error checking.
 - iucv: Add name of net_device to iucvMagic to more than one
         connection between two guests.
 - qeth: Don't send IPA command if card is not in state SOFTSETUP or UP.
 - qeth: Fix number base in simple_strtoul call for buffer_count attribute.
 - qeth: Fix reallocating of buffers when buffer_count attribute is changed.
 - qeth: Correct handling of return codes in qeth_realloc_buffer_pool.
 - qeth: Don't call dev_close/dev_open on STOPLAN/STARTLAN commands.
         Use netif_carrier_off/netif_carrier_on instead.
