I'm afraid I'm going to have to leave review of this to someone who is
clueful about configfs. But it seems reasonable.

Code clean-up for tsi108_eth network driver.
This patch removes not needed dummy read and the corresponding comment.
The PHY logic requires two reads from the status register to get
current link status. This is done correctly inside mii_check_media().

I know that's already in mainline but, man, that code is nasty. It has
stuff indented 7 levels or so and is virtually impossible to read.
This:

is also completely bogus for arch-independent code. If someone ever
wants to do ppc without sparsemem (or redoes internal sparsemem
interfaces), this code will break.
Also, keeping your own mapping of all of memory is really nasty. With
SPARSEMEM_EXTREME/VMEMMAP you can have extremely sparse physical memory,
and this:
> ehea_bmap.entries = high_section_index + 1;
> ehea_bmap.vaddr = vmalloc(ehea_bmap.entries * sizeof(*ehea_bmap.vaddr));
could theoretically consume all of memory if the sections are very sparse.
Could you please try to explain what the heck this driver is doing?
We'll try to fix up the generic interfaces so that you can deal with
things in a more generic fashion, but it can't stay this way.
Also, just ripping down and completely re-doing the entire mass of cards
every time a 16MB area of memory is added or removed seems like an
awfully big sledgehammer to me. I would *HATE* to see anybody else
using this driver as an example to work off of? Can't you just keep
track of which areas the driver is actually *USING* and only worry about
changing mappings if that intersects with an area having hotplug done on
it?
Can you please give it some CodingStyle love and make it so that it
doesn't indent so much? Something like this:

It would be a bug -unless- you are holding the update-side lock.

Ummm... "It depends." ;-)
Keeping in mind that I am not an expert on this part of the kernel, I
would guess that qeth_l3_free_vlan_addresses4() is not particularly
performance-sensitive, so I don't see any reason in_dev_get/in_dev_put
would be a problem. If it turns out that qeth_l3_free_vlan_addresses4()
is in fact performance-sensitive, then rcu_read_lock()/rcu_read_unlock()
would be a better choice.
Thanx, Paul

A logic mishap caused the adapter to keep link while we can
disable it due to WoL not being active, and vice versa.

* [PATCH 4/6] ixgbe: warn when device is in a x4 or lower width slot
From: Auke Kok @ 2008-02-11 17:25 UTC (permalink / raw)

It's easy to oversee this issue when working with this card
as evrything will work OK but performance is severely limited
(something like 1.5gbit on a x1 link) if the pci-express
slot does not offer more bandwidth.

* [PATCH 2/6] e1000: warn if this driver is used for e1000e devices
From: Auke Kok @ 2008-02-11 17:25 UTC (permalink / raw)
To: jeff; +Cc: netdev, e1000-devel
In-Reply-To: <20080211172539.29090.99369.stgit@localhost.localdomain>
We're already starting to see reports from users still
using e1000 where they should be using e1000e now that this is
actually possible. Just to prevent some of this thrash, add
a big warning on load on these devices that people should
switch to e1000e.

If __devinit marked code is still discarded after initial setup then NACK. open can be called at any time the
interface is ifup'ed. Its most definitely not adapter init code (that's all done in probe).

Hi,
Could you explain what exactly scheduling rules do you mean here,
and why disabling interrupts is the best solution for this?

* Re: AW: Problem receiving multicast/promiscuous-mode with kernel.2.6.24
From: David Stevens @ 2008-02-11 19:18 UTC (permalink / raw)
To: Reither Robert; +Cc: netdev
In-Reply-To: <BA41E8A07B73A041948C2E3A4EF6239D062F0C@av-digital-exch.avdigital.at>
Another relevant piece of information is what the socket is
bound to; "netstat -au" will tell you if you're bound to an address
that will match the incoming multicast packets.
If you suspect that the VLAN device is the problem, then it'd be
a good idea to try it on ordinary ethernet.
Re: imr_ifindex; using a "0" ifindex and INADDR_ANY interface is valid,
but it usually doesn't make sense. What it means is "I don't care what
interface I join the group on". But you'll only receive multicasts
delivered to the group on the interface the kernel picks for you, which
often won't be the one you really want.

* [PATCH 3/5 v3] Tsi108_eth: remove not needed code
From: Alex Bounine @ 2008-02-11 19:35 UTC (permalink / raw)
To: jgarzik, netdev; +Cc: linuxppc-dev, tie-fei.zang, jwboyer
Code clean-up for tsi108_eth network driver.
This patch removes not needed dummy read and the corresponding comment.
The PHY logic requires two reads from the status register to get
current link status. This is done correctly inside mii_check_media().
