* Re: [PATCH] mv643xx_eth: fix byte order when checksum offload is enabled

The Marvell Orion system on chips have an integrated mv643xx MAC.
On these little endian ARM devices mv643xx will oops when checksum
offload is enabled. Swapping the byte order of the protocol and
checksum solves this problem.

Resubmitted after comments from Al Viro. udp_hdr(skb)->check returns
a __sum16 so I have called the function sum16_as_be(). Again lightly
tested only on two Marvell Orion boards.

The code is already gone for about half a year, the config option
has been kept around to select the replacement options for easier
upgrades. This seems long enough, people upgrading from older
kernels will have to reconfigure a lot anyway.

[MACVLAN]: Fix thinko in macvlan_transfer_operstate()
When the lower device's carrier is off, the macvlan devices's
carrier state should be checked to decide whether it needs to
be turned off. Currently the lower device's state is checked
a second time.
This still works, but unnecessarily tries to turn off the
carrier when its already off.

[NET_SCHED]: sch_ingress: remove useless printk
The printk about ingress qdisc registration error can't be triggered under
normal circumstances. Since register_qdisc only fails for two identical
registrations, the only way to trigger it is by loading the sch_ingress
modules multiple times under different names, in which case we already
return -EEXIST to userspace.

These patches clean up sch_ingress by reformatting the code to match the
usual kernel style, removing lots of debugging statements that seem
unnecessary after years of stable operation, removing some "future use"
stuff that doesn't seem likely to ever get used and some minor additional
cleanups.

Hello,
net 2.6.25 is broken when building with the wireless/iwlwifi
subtree; we get the following errors (we noticed that iwl_down() and
iwl_resume()
implementation do exist in garzik tree, but there are more differences
so a simple
patch with only adding these two methods might be risky)

That doesn't work in this case since nf_bridge_info contains
unsigned long data[32 / sizeof(unsigned long)];
and I don't want to assign each array element seperately.

Hi David
Thanks for beating into my thick scull that this is in 2.6.25. I missed that
initially.
Anyway, here is a patch that sets the correct value.

Subject: [PATCH] [SCTP] Correctly initialize error when parameter validation failed.
When parameter validation fails, there should be error causes
that specify what type of failure we've encountered. If the
causes are not there, we lacked memory to allocated them. Thus
make that the default value for the error.

I agree, bogus, and in fact I've already removed it from our development
version of ixgbe. Right now I wanted to report I can't remove e1000 at
all on 2.6.24-rc8+git
I continually get the
kernel: unregister_netdevice: waiting for eth2 to become free. Usage
count = 1
Where 2.6.24-rc5 e1000 is okay still. Seems like maybe we are still
missing a netif_rx_complete or a napi_disable somewhere.
I don't think this problem has anything to do with the irq_sem right
now. Something is still badly broken. I am just using the interface
regularly (no heavy load) and I can't unload the module.

The mainline kernel doesn't have ESFQ, so the distribute version of iproute2
does not. If your distro chooses to add ESFQ to their kernel, then they
need to extend tc as well.

Looks good Samuel.
Thank you for improving on my original suggested patch.
Now let's hope someone queues it up for mainline :)
