[patch 6/7] s390: introduce guestLan sniffer support in qeth
From: Peter Tiedemann <ptiedem@de.ibm.com>
- introduce guestLan sniffer support in qeth
feature allows a linux in a virtual machine
guest to become a network LAN sniffer,
monitoring and recording the networking traffic
within an entire guestLan.

[patch 5/7] s390: fix recovery failure of non-guestLAN devices
From: Frank Pavlic <fpavlic@de.ibm.com>
- Recovery of non-guestLAN Layer 2 device failed due to
trying to register the real MAC address we got from
the READ_MAC adapter parameters command.
We have to keep the "old" MAC address when we process
the reply of a READ_MAC.

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.

minor qeth fixes:
- free old skb in qeth_realloc_headroom after duplicating skb
- disable IPV6 support for Hipersockets devices
- call ccw_device_set_offline on every channel regardless
of the return value of the prior ccw_device_set_offline calls
- allocate qdio structures in DMA-area
- schedule recovery of appropriate card
when cable has been inserted again.
- add missing initialization of card->lock
- write sequence number in skb->cb for SNA protocol which
requires strictly serialized packets.

[patch 4/4] s390: qeth driver fixes .
From: Frank Pavlic <pavlic@de.ibm.com>
- Clear read channel first prior to using ccw_device_set_offline.
- use QETH_DBF_TEXT instead of QETH_DBF_SPRINTF
- invoke qeth_halt_channel and qeth_clear_channel for all channels,
even if halt/clear for one of the channel fails.

[patch 3/4] s390: TSO related fixes in qeth driver
From: Frank Pavlic <pavlic@de.ibm.com>
TSO related fixes :
- changing value of large_send attribute while network traffic
is running caused program check and thus device recovery.
- Due to hardware restriction discard packet when it exceeds 60K
otherwise qeth will cause program checks and thus traffic stall
when trying to send such huge packets.

`gcc -W' likes to complain if the static keyword is not at the beginning of
the declaration. This patch fixes all remaining occurrences of "inline
static" up with "static inline" in the entire kernel tree (140 occurrences in
47 files).
While making this change I came across a few lines with trailing whitespace
that I also fixed up, I have also added or removed a blank line or two here
and there, but there are no functional changes in the patch.

This patch changes the memory allocation method for the s390 debug feature.
Trace buffers had been allocated using the get_free_pages() function before.
Therefore it was not possible to get big memory areas in a running system due
to memory fragmentation. Now the trace buffers are subdivided into several
subbuffers with pagesize. Therefore it is now possible to allocate more
memory for the trace buffers and more trace records can be written.
In addition to that, dynamic specification of the size of the trace buffers is
implemented. It is now possible to change the size of a trace buffer using a
new debugfs file instance. When writing a number into this file, the trace
buffer size is changed to 'number * pagesize'.
In the past all the traces could be obtained from userspace by accessing files
in the "proc" filesystem. Now with debugfs we have a new filesystem which
should be used for debugging purposes. This patch moves the debug feature
from procfs to debugfs.
Since the interface of debug_register() changed, all device drivers, which use
the debug feature had to be adjusted.

[patch 10/10] s390: qeth bug fixes.
From: Frank Pavlic <pavlic@de.ibm.com>
qeth network driver related changes:
- due to OSA hardware changes in TCP Segmentation Offload
support we are able now to pack TSO packets too.
This fits perfectly in design of qeth buffer handling and
sending data respectively.
- remove skb_realloc_headroom from the sending path since
hard_header_len value provides enough headroom now.
- device recovery behaviour improvement
- bug fixed in Enhanced Device Driver Packing functionality

[patch 7/10] s390: qeth bug fixes.
From: Frank Pavlic <pavlic@de.ibm.com>
qeth network driver changes:
- Removed redundant code, use the same qeth_fill_buffer_frag
for TSO path either
- Using skb->frags solely is not correct since skb->data still
points to the beginning of the whole data, even when it is
a small portion we have to fill the qdio buffer with it.

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!
