This patch fixes the following bugs with offline diagnostics
code(run with "ethtool -t").
1. After running offline diagnostics, adapter would report
corrupted packets on receive. This was because of adapter not
being brought out of "RLDRAM test mode".
2. Current EEPROM test works only for Xframe I. Since Xframe II
uses different interface(SPI), support for this interface has
been added. Also, since SPI supports write access to all areas
of EEPROM, negative testing is done only for Xframe I.
3. Return values from subfunctions of offline diagnostics have
been corrected.
4. In register test, expected value from rx_queue_cfg register
is made to depend on adapter type.
5. After the test, need to restore values at EEPROM offsets
0x4F0 and 0x7F0. These locations were modified as part of test.
6. Use macro SPECIAL_REG_WRITE for write access to mc_rldram_test_ctrl
register. Also, couple of unnecessary writes to mc_rldram_test_ctrl
have been removed.

- added typedef unsigned int __nocast gfp_t;
- replaced __nocast uses for gfp flags with gfp_t - it gives exactly
the same warnings as far as sparse is concerned, doesn't change
generated code (from gcc point of view we replaced unsigned int with
typedef) and documents what's going on far better.

Replicate IGMP frames across all slaves in activebackup mode. This
ensures fail-over is rapid for multicast traffic as well. Otherwise,
multicast traffic will be lost until the next IGMP membership report
poll timeout.
This is conceptually similar to the treatment of IGMP traffic in
bond_alb_xmit. In that case, IGMP traffic transmitted on any slave
is re-routed to the active slave in order to ensure that multicast
traffic continues to be directed to the active receiver.

Patch has been tested on IA64 platform with Xframe II adapter,

in throughput(both Tx and Rx) was observed and a reduction by 7%
in CPU utilization during Tx test.

Unfortunately, [your patch] might address the crash but doesn't address
the real problem. It turns out that the problem is one of padding
(the firmware cksum engine works only on 32-bit chunks, yuck), so
the special casing for length == 1 wasn't sufficient anyway.
This patch addresses the issue, as well the other issue of i386 +
CONFIG_HIGHMEM being broken. It is pretty much the same workaround
that Adaptec themselves used in their Windows driver. I have yet to
check if it fixes the problem when the skb is non-linear, but this
patch _will_ solve the problem for 99% of the users out there (those
not using sendfile).

This patch removes backwards compatibility for old ifenslave

I did not similarly modify ifenslave itself; with sysfs on the

local->hw_priv was being freed and set to NULL just before calling
prism2_free_local_data(). However, this may expose a race condition in
which something ends up trying to use hw_priv during shutdown. I
haven't noticed this happening, but better be safe than sorry, so
let's postpone hw_priv freeing to happen only after
prism2_free_local_data() has returned.

Host AP driver used hardware model specific dev_open/close handlers
that were called on dev_open/close if the hardware driver had
registered the handler. These were only used for hostap_cs and only
for tracking whether any of the netdevs were UP. This information is
already available from local->num_dev_open, so there is not need for
the special open/close handler.
Let's get rid of these handlers. In addition to cleaning up the code,
this fixes a module refcounting issue for hostap_cs where ejecting the
card while any of the netdevs were open did not decrement refcount
properly.

The following patch renames __in_dev_get() to __in_dev_get_rtnl() and
introduces __in_dev_get_rcu() to cover the second case.
1) RCU with refcnt should use in_dev_get().
2) RCU without refcnt should use __in_dev_get_rcu().
3) All others must hold RTNL and use __in_dev_get_rtnl().
There is one exception in net/ipv4/route.c which is in fact a pre-existing
race condition. I've marked it as such so that we remember to fix it.

HyperTransport interface is not responsible for PCI transactions
and so the re-ordering is more likely done by the VIA north bridge.

or VIA.
