[patch 00/11] s390: network device driver fixes for 2.6.26

[frank.blaschka]

Hi Jeff,

here are some s390 network device driver fixes for 2.6.26

Klaus Wacker (1)
lcs: CCL-sequ. numbers required for protocol 802.2 only.

Ursula Braun (3)
netiucv: get rid of in_atomic() use
qeth/cu3088/ccwgroup: Unify parsing for group attribute.
qeth: read number of ports from card

Peter Tiedemann (1)
qeth: module size reduction.

Frank Blaschka (5)
qeth: layer 3 support vlan IPv6 on hiper socket
qeth: provide get ethtool settings
qeth: rework fast path
qeth: layer 3 add missing dev_open/close to ccwgroup handler
qeth: layer 2 allow ethtool to set TSO

Cornelia Huck (1)
netiucv: Fix missing driver attributes.

Thanks,
        Frank

[patch 03/11] ccwgroup: Unify parsing for group attribute.

[frank.blaschka]

[-- Attachment #1: 702-cio-ccwgroup.diff --]
[-- Type: text/plain, Size: 8146 bytes --]

From: Ursula Braun <braunu@de.ibm.com>

Instead of having each driver for ccwgroup slave device parsing the
input itself and calling ccwgroup_create(), introduce a new function
ccwgroup_create_from_string() and handle parsing inside the ccwgroup
core.

[patch 04/11] qeth module size reduction.

From: Peter Tiedemann <ptiedem@de.ibm.com>

Replace complex macro for s390dbf calls by equivalent function. This reduces
module size about 10% without visible performance impact.

[patch 06/11] qeth: provide get ethtool settings

[frank.blaschka]

[-- Attachment #1: 705-qeth-ethtool.diff --]
[-- Type: text/plain, Size: 5407 bytes --]

From: Frank Blaschka <frank.blaschka@de.ibm.com>

Load balancing bonding queries the speed of the slave interfaces.
To support a bond consisting of different slave speeds we have to
report the speed by ethtool settings.

[-- Type: text/plain, Size: 1494 bytes --]

From: Frank Blaschka <frank.blaschka@de.ibm.com>

In case the ccwgroup device is set online/offline we have to run
the corresponding dev_open/close for the netdevice.
