[PATCH] s390: network device driver.
From: Martin Schwidefsky <[email protected]>
Network driver changes:
- iucv: Fix special case of a "Connection Pending" interrupt within
iucv_do_int.
- netiucv: Revoke broken iucvMagic change for more than one connection.
- qeth: Fix string parsing in notifier_register attribute function.
- qeth: Add code for socket ioctl SIOC_QETH_GET_CARD_TYPE.
- qeth: Fix debug log entry and buffer copy in qeth_snmp_command_cb.
- qeth: Fix race on qeth_dbf_txt_buf.
