The 10Xpress PHY supports flash upgrades through MDIO, but needs to be
put in upgrade mode at power-up. This adds a module parameter and other

The SFC4000 controller does not have hardware support for TSO, and the
core GSO code incurs a high cost in allocating and freeing skbs. This
TSO implementation uses lightweight packet header structures and is
substantially faster.

Fix a long-standing bug/misunderstanding between the

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/)

The syncppp layer wants a mid-level netdev private pointer.
It was using netdev->priv but that only worked by accident,
and thus this scheme was broken when the device private

update syncppp and all users, and remove the HDLC_PPP broken

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
