[PATCH] s390: network device 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.
