Or maybe use percpu storage for that...
I am not sure if cookie_hash() is always called with preemption disabled.
(If not, we have to use get_cpu_var()/put_cpu_var())
[NET] IPV4: lower stack usage in cookie_hash() function
400 bytes allocated on stack might be a litle bit too much. Using a
per_cpu var is more friendly.

Without low power patch I have:

net eth0: link down
net eth0: normal mode
net eth0: multicast mode

multicast is called by network stacks, no control by the driver. The driver
just print message.
I don't know why enc28j60_set_multicast_list() are called more than once.
When you do an ifconfig up the driver reset the chip, so you see link down
before link up message.

I don't follow you anymore.
To change duplex mode the link must be down.
enc28j60_setlink() reinitialize the chip with new duplex mode,
enc28j60_hw_init() never brings link up.
I propose you to add set_lowpower(true) in the enc28j60_probe() and in
the enc28j60_net_close() after enc28j60_hw_disable().
Probably we don't need to set_lowpower(false) in enc28j60_net_open() since
it performs a soft reset with enc28j60_hw_init().
Do you agree?

After a couple of :
ifconfig eth0 down
(wait just 1 second)
ifconfig eth0 up
the network is frozen.
If I do another
ifconfig eth0 down
(wait just 1 second)
ifconfig eth0 up
restarts.
It's random, no rule.

* [PATCH 0/7] PS3: gelic: gelic updates and wireless support
From: Masakazu Mokuno @ 2008-02-07 10:57 UTC (permalink / raw)
To: jgarzik; +Cc: netdev, geoffrey.levand, Geert Uytterhoeven
Hi,
This set is a collection of patches I submitted before in this ML on
last December and a patch that adds the wireless support to PS3.
The wireless bit (#7) is already ACKed by John <linville@tuxdriver.com>
and Dan <dcbw@redhat.com>. The ethernet bits have been reviewed and
have no obvious outstanding comments.
Please apply for 2.6.25.
[1] PS3: gelic: Fix the wrong dev_id passed
[2] PS3: gelic: Add endianness macros
[3] PS3: gelic: Code cleanup
[4] PS3: gelic: Remove duplicated ethtool handlers
[5] PS3: gelic: Add support for port link status
[6] PS3: gelic: Add support for dual network interface
[7] PS3: gelic: Add wireless support for PS3

PS3: gelic: Fix the wrong dev_id passed
The device id for lv1_net_set_interrupt_status_indicator() is wrong.
This path would be invoked only in the case of an initialization failure.

PS3: gelic: Add endianness macros
Mark the members of the structure for DMA descriptors with proper endian
annotations and use the appropriate accessor macros.
As the gelic driver works only on PS3, all these macros will be
expanded to null.

To: jgarzik; +Cc: netdev, geoffrey.levand, Geert Uytterhoeven
PS3: gelic: code cleanup
Code cleanup:
- Use appropriate prefixes for names instead of fixed 'gelic_net'
so that objects of the functions, variables and constants can be estimated.
- Remove definitions for IPSec offload to the gelic hardware. This
functionality is never supported on PS3.
- Group constants with enum.
- Use bitwise constants for interrupt status, instead of bit numbers to
eliminate shift operations.
- Style fixes.

* [PATCH 6/7] PS3: gelic: Add support for dual network interface
From: Masakazu Mokuno @ 2008-02-07 10:58 UTC (permalink / raw)
To: jgarzik; +Cc: netdev, Geert Uytterhoeven, geoffrey.levand
PS3: gelic: Add support for dual network interface
Add support for dual network (net_device) interface so that ethernet
and wireless can own separate ethX interfaces.
V2
- Fix the bug that bringing down and up the interface keeps rx
disabled.
- Make 'gelic_net_poll_controller()' extern , as David Woodhouse
pointed out at the previous submission.
- Fix weird usage of member names for the rx descriptor chain
V1
- Export functions which are convenient for both interfaces
- Move irq allocation/release code to driver probe/remove handlers
because interfaces share interrupts.
- Allocate skbs by using dev_alloc_skb() instead of netdev_alloc_skb()
as the interfaces share the hardware rx queue.
- Add gelic_port struct in order to abstract dual interface handling
- Change handlers for hardware queues so that they can handle dual
{source,destination} interfaces.
- Use new NAPI functions
This is a prerequisite for the new PS3 wireless support.

* [PATCH 7/7] PS3: gelic: Add wireless support for PS3
From: Masakazu Mokuno @ 2008-02-07 10:58 UTC (permalink / raw)
To: jgarzik; +Cc: netdev, Geert Uytterhoeven, geoffrey.levand
Subject: PS3: gelic: Add wireless support for PS3
Signed-off-by: Masakazu Mokuno <mokuno@sm.sony.co.jp>
Acked-by: Dan Williams <dcbw@redhat.com>
Acked-by: John W. Linville <linville@tuxdriver.com>
---
This is the version 2 of the re-worked (rewritten) version of the wireless
support driver for PS3. The version 1 of the new driver was submitted on 13th
Dec. 2007 (and the old one was submitted to net-dev ML in June 2007).
Major differences with the old driver are:
- The new driver has a separate ethX interface from ethernet.
They share the same MAC address.
- Thus we can use both ethernet and wireless simultaenously.
- The new driver returns AP's cipher information by the common IE
format in the scan information.
- Cipher selection is done via the common wireless extension way
V2 changes:
- Emit more null IWAP events at appropriate timings, as Dan Williams
pointed out at the V1 submission.
- Fix sparse warnings
o make some functions as static
o use NULL for pointer instead of 0
- Remove extra space

Sorry,
let me repeat what I said in previous mail.
I propose you to add set_lowpower(true) in the enc28j60_probe() and in
the enc28j60_net_close() after enc28j60_hw_disable().
Probably we don't need to set_lowpower(false) in enc28j60_net_open() since
it performs a soft reset with enc28j60_hw_init() (not sure).
Furthermore, as you suggested, we also need to remove hw_init() from the
setlink()
because hw_init() is called when we bring link up.

Subject: [RFC] remove skb->dev NULL assignation
From: Daniel Lezcano <dlezcano@fr.ibm.com>
I was trying to figure out why in the tcp_v4_rcv/tcp_v6_rcv function,
the skb->dev field is set to NULL. There is certainly a good reason,
but I was not able to find it.
Is it possible to remove this ?

It is illegal to reference a device outside of the netif_receive_skb()
code path without taking a reference to it.
Since we are queueing it to a socket, we have to NULL out the skb->dev
since thee packets lifetime is being expanded outside of that allowed
window.

* [PATCH] rtnetlink.c: send a single notification on device state changes
From: Laszlo Attila Toth @ 2008-02-07 11:57 UTC (permalink / raw)
To: David Miller; +Cc: netdev, Laszlo Attila Toth
In-Reply-To: <20080205.175337.266368079.davem@davemloft.net>
In do_setlink() a single notification is sent at the end of the function
if any modification occured. If the address has been changed, another
notification is sent.
Both of them is required because originally only the NETDEV_CHANGEADDR
notification was sent and although device state change implies address
change, some programs may expect the original notification. It remains
for compatibity.
If set_operstate() is called from do_setlink(), it doesn't send
a notification, only if it is called from rtnl_create_link() as earlier.

According to some OOPSes reported by Jann it seems ax25_kick
tries to clone NULL skbs sometimes. Probably there is needed
a sock lock, but until it's checked more this patch should
help to avoid this. There are probably also cases where ax25
->paclen == 0 can happen: let's check for this.
I attach this patch for testing purpose only.

Better descriptions, yes. Of course.
But are you saying to NOT name the file in its comments?
I am surprised. If I am reading correctly, then I disagree.
Is the exclusion of the name of the source file from its comments
a stylistic decision the other kernel developers have agreed to?
Or is it tied to automation? Or have I (hopefully) misunderstood?

The DM9000 datasheet (or rather the application notes) describes two distinct
