-stable review patch. If anyone has any objections, please let us know.
------------------
From: Stephen Hemminger <shemminger@osdl.org>
This fixes the RCU race on bridge delete interface. Basically,
the network device has to be detached from the bridge in the first
step (pre-RCU), rather than later. At that point, no more bridge traffic
will come in, and the other code will not think that network device
is part of a bridge.
This should also fix the XEN test problems. If there is another
2.6.13-stable, add it as well.

The receive path for fib_lookup netlink messages is lacking sanity

[patch 2/3] s390: minor qeth network driver fixes
From: Frank Pavlic <pavlic@de.ibm.com>
- use netif_carrier_on/off calls to tell network stack
link carrier state
- fix possible kfree on NULL
- PDU_LEN2 is at offset 0x29 otherwise OSN chpid won't initialize

[patch 1/3] s390: some minor qeth driver fixes
From: Frank Pavlic <pavlic@de.ibm.com>
- let's have just one function for both ,input and output queue
to check qdio errors
- add /proc/s390dbf/qeth_qerr entries for outbound processing
- check removed for layer2 device in qeth_add_multicast_ipv6
- NULL pointer dereference with bonding and VLAN device fixed
- minimum length check for portname fixed

* [2.6 patch] kill drivers/net/irda/sir_core.c
From: Adrian Bunk @ 2005-12-13 2:29 UTC (permalink / raw)
To: Andrew Morton; +Cc: Jean Tourrilhes, jgarzik, netdev, linux-kernel
EXPORT_SYMBOL's do nowadays belong to the files where the actual
functions are.
Moving the module_init/module_exit to the file with the actual functions
has the advantage of saving a few bytes due to the removal of two
functions.

This patch against 2.6.14 converts the natsemi driver to use NAPI. It
was originally based on one written by Harald Welte, though it has since
been modified quite a bit, most extensively in order to remove the
ability to disable NAPI since none of the other drivers seem to provide
that functionality any more.
Signed-off-by: Mark Brown <broonie@sirena.org.uk>

This revision of the patch:
- Doesn't sleep with the device spinlock held in suspend().
- Improves the synchronisation between poll() and the shutdown paths.
