In the near future, the driver core is going to not allow direct access
to the driver_data pointer in struct device. Instead, the functions
dev_get_drvdata() and dev_set_drvdata() should be used. These functions
have been around since the beginning, so are backwards compatible with
all older kernel versions.
Thanks to Sebastian Ott <sebott@linux.vnet.ibm.com> for fixing a few
typos in my original version of this patch.

This patch converts unicast address list to standard list_head using
previously introduced struct netdev_hw_addr. It also relaxes the
locking. Original spinlock (still used for multicast addresses) is not
needed and is no longer used for a protection of this list. All
reading and writing takes place under rtnl (with no changes).
I also removed a possibility to specify the length of the address
while adding or deleting unicast address. It's always dev->addr_len.
The convertion touched especially e1000 and ixgbe codes when the
change is not so trivial.

If a qeth device is plugged off, setting the device online stops in
state HARDSETUP and a failure is reported to the base cio-layer
causing halt/clear to be invoked. Replugging the device again triggers
a qeth recovery without notification of the cio-layer. If a device
is ungrouped in this state, the qeth set_offline function is not
invoked, because the corresponding ccwgroup device is not in state
ONLINE. Then incoming traffic is still handled by the qdio layer
resulting in a crash in qeth_l<x>_qdio_input_handler, because (part
of) the qeth data structures for this device are already removed.
Solution: After replugging the device qeth recovery should lead to a
working net device. Thus a "LAN offline" result when setting a qeth
device online must not report a failure to the base cio-layer.

Errors from SIGA instructions are stored in the per queue qdio_error

when multiple error conditions occur simultanously.
Report SIGA errors immediately in the return value of do_QDIO so the
upper layer can react and SIGA errors no longer interfere with other
errors.

Problem: A STARTLAN command from the adapter may arrive while a
qeth recovery is currently running with a failed qeth
STARTLAN. Usually qeth schedules a recovery when
receiving a STARTLAN command from the adapter. But
another recovery scheduled while a recovery is already
running never starts. Thus the qeth-administered
lan_online flag remains zero in this scenario, even
though the adapter-STARTLAN has happened.
Solution: Set lan_online flag for a received STARTLAN from the
adapter in case scheduled recovery does not start.

2. ip_list handling after deregister failure or normal ip address:

Recently, Wang Chen submitted a patch
(d30f53aeb3) to move a call to netif_rx(skb)
after a subsequent reference to skb, because netif_rx may call kfree_skb on
its argument. netif_rx_ni calls netif_rx, so the same problem occurs in
the files below.
I have left the updating of dev->last_rx after the calls to netif_rx_ni
because it seems time dependent, but moved the other field updates before.
This was found using the following semantic match.

smsgiucv is a driver that relies on iucv to work properly. If

lpar the following scenario happens:
iucv is initialized early as a subsystem. It checks for z/VM and
returns with EPROTONOTSUPPORT. Later smsgiucv tries to run
driver_register with iucv_bus as bus. As this bus is not
initialized the driver core and list debugging issue several
warnings and oopses.
Solution is to let smsgiucv also check for z/VM and return
EPROTONOTSUPPORT as well.
