Increase the handoff timeout to 512ms so as to give the aeluros based
NICs sufficient time to handoff without relying on the msleep() being
sloppy, and accidentally sleeping way longer than the 20ms we specified
in 20 separate 1ms sleeps.
Fix typo in the handoff sleep delay, which made it additive, not
exponential.

When, for some reason, the rt2x00pci module fails to allocate DMA memory for
the queues, it tries to undo the complete initialization of the PCI device,
including freeing of the irq. This results in the following error in dmesg, as
the irq hadn't been requested yet:
[ 78.123456] Trying to free already-free IRQ 17
Fix this by implementing proper error handling code, instead of just using the
full uninitialization function.

During initialization the initialize() callback function
in rt2x00pci and rt2x00usb will cleanup the mess they made.
rt2x00lib shouldn't call uninitialize because the callback function already
cleaned up _and_ the DEVICE_INITIALIZED isn't set which causes the
rt2x00lib_uninitialize() to halt directly anyway. All that is required
to be cleaned up by rt2x00lib is the queue, and that can be done by
calling rt2x00queue_uninitialize() directly.

rt2x00pci allocates DMA for descriptor and data,
rt61pci doesn't use this for the beacon, but it can
use the descriptor part as temporary buffer instead
of using pskb_expand_head().
Using this temporary buffer is obviously much better
then reallocating the skb buffer...
At the same time we can set the data length for the
beacon queue at 0, to make sure no DMA is allocated for
data (but just for the descriptor).

If session is NULL, it is not possible to access its name field. So I
have split apart the printing of the error message to drop the
printing of the name field in this case.
The macro PRINTK actually only evaluates its arguments starting with
the third one if the bitwise conjunction of the first two is non-zero.
Normally, this conjunction would only be non-zero if debugging mode
were turned on, but when session is NULL, the first argument in both
the old and new code is -1, and thus the bitwise conjunction is true.
Perhaps a different strategy is desired, such as using tunnel->debug,
which session->debug is initialized to, but tunnel can also be NULL,
so this does not completely solve the problem.
This problem was found using the following semantic match
(http://www.emn.fr/x-info/coccinelle/)

As noticed by Ben Greear, macvlan crashes the kernel when unloading the
module. The reason is that it tries to clean up the macvlan_port pointer
on the macvlan device itself instead of the underlying device. A non-NULL
pointer is taken as indication that the macvlan_handle_frame_hook is
valid, when receiving the next packet on the underlying device it tries
to call the NULL hook and crashes.
Clean up the macvlan_port on the correct device to fix this.

Taken from http://bugzilla.kernel.org/show_bug.cgi?id=10577
I was unable to access a computer containing an Intel EtherExpress 16 network
card using IPv6.
I traced this to failure of neighbour discovery. When I used an "ip -6 neigh
add" command, on the computer attempting access, to insert a binding between
the IPv6 address of the computer with the Intel EtherExpress 16 network card
and the card's ethernet address, I was able to access that computer using
IPv6.
Neighbour discovery requires working multicast. The driver sources file
eexpress.c contains an approximately 30 line function eexp_setup_filter used
when loading multicast addresses.
I found 3 problems in this function
1) It wrote the number of multicast addresses to the card instead of the
number of bytes in the multicast addresses.
2) When loading multiple multicast addresses it loaded the first one
provided multiple times instead of loading each one once.
3) The setting of pointer 'data' from 'dmi->dmi_addr' occured before the
test for the error situation of 'dmi' being NULL.
Correcting these problems allows the computer with the Intel EtherExpress 16
network card to found by IPv6 neighbour discovery.
p.s. There is some information on the Intel EtherExpress 16 at
http://www.intel.com/support/etherexpress/vintage/sb/cs-013500.htm

This patch adds support for the BM PHY, a new PHY model being used
on ICH9-based implementations.
This new PHY exposes issues in the ICH9 silicon when receiving
jumbo frames large enough to use more than a certain part of the
Rx FIFO, and this unfortunately breaks packet split jumbo receives.
For this reason we re-introduce (for affected adapters only) the
jumbo single-skb receive routine back so that people who do
wish to use jumbo frames on these ich9 platforms can do so.
Part of this problem has to do with CPU sleep states and to make
sure that all the wake up timings are correctly we force them
with the recently merged pm_qos infrastructure written by Mark
Gross. (See http://lkml.org/lkml/2007/10/4/400).
To make code read a bit easier we introduce a _IS_ICH flag so
that we don't need to do mac type checks over the code.

The firmware on MPC8610HPCD boards enables ULI ethernet and leaves it

The sysfs layer has an internal protection, that ensures, that
all the process sitting inside ->sore/->show callback exits
before the appropriate entry is unregistered (the calltraces
are rather big, but I can provide them if required).
On the other hand, bonding takes rtnl_lock in
a) the bonding_store_bonds, i.e. in ->store callback,
b) module exit before calling the sysfs unregister routines.
Thus, the classical AB-BA deadlock may occur. To reproduce run
# while :; do modprobe bonding; rmmod bonding; done
and
# while :; do echo '+bond%d' > /sys/class/net/bonding_masters ; done
in parallel.
The fix is to move the bond_destroy_sysfs out of the rtnl_lock,
but _before_ bond_free_all to make sure no bonding devices exist
after module unload.
