This patch improves FFDC (first failure data capture) by requesting
a hardware trace in case the device driver, the hardware or a user
detects an error.

Set rx csum default to hw checksumming again.
Remove sysfs interface for rx csum (checksumming) and TSO (large_send).
With the new hw_features it does not work to keep the old sysfs
interface in parallel. Convert options.checksum_type to new hw_features.

Isolate data connection to a shared OSA card against other data
connections to the same OSA card. Connectivity between isolated
data connections sharing the same OSA card is therefore possible only
through external network gear (e.g. a router).

z/VM Virtual Switch Port Isolation allows guests on a VLAN UNAWARE
virtual switch to be isolated from other guests on the VSWITCH.
(See z/VM Apars VM64281 and VM64463).
The Linux qeth driver is affected, because it has to handle new
error codes introduced with the z/VM VSWITCH Port Isolation support.

1. ip_list handling after deregister failure of multicast address:
   If error code "MC Address not found" is returned do not re-add
   multicast address to ip_list.
   For other error codes readd multicast address at the end of
   function qeth_delete_all_mc.
2. ip_list handling after deregister failure or normal ip address:
   If error code "IP Address not found" is returned do not re-add
   multicast address to ip list.
   This is especially important in IP address takeover scenarios,
   to enable re-takeover of a taken over IP address.

Exclusive usage of OSA-cards has been introduced. Even though Linux
does not make use of it, qeth should be prepared to receive a bad RC
for some initialization steps. A meaningful message is now given,
if an OSA-device is set online, even though the OSA-adapter is already
exclusively used by another host.

Previous fix patches added a bunch of trailing whitespace,
which git-applymbox complained loudly about.

- Remove all CVS generated information like e.g. revision IDs from
  drivers/s390 and include/asm-s390 (none present in arch/s390).

- Add newline at end of arch/s390/lib/Makefile to avoid diff message.

	This patch introduces new feature in qeth:
	qeth enhancement provides the device driver support for
        the Communication Controller for Linux on System z9 and zSeries
        (CCL), which is software that enables running the Network Control
        Program (NCP) on a zSeries machine. The OSA CDLC support is based
        on a new IBM mainframe CHPID type called Open Systems Adaper for
        NCP (OSN). In case of OSN qeth communicates with the type-OSN
        OSA-card on one hand, and with the CCL-kernel-component Network
        Device Handler (NDH) on the other.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
