This patch adds a workaround for lost MSI interrupts. There is a race condition in the HW in which future interrupts could be missed. The workaround is to toggle the MSI irq mask. Signed-off-by: Ayaz Abdulla <aabdulla@nvidia.com>

Because of the bugs in Adam's MD5/SACK fix I need to rebase the tree to get rid of it. Adam, please post a complete new patch once you've fixed that SACK option adding problem. Thanks. The only other local change in net-2.6 is Dave Young's bluetooth deadlock fix which I'll put into the rebased tree. I hate to do this but: 1) I didn't pull any of this into net-next-2.6 yet, so it hasn't propagated there. 2) I don't want Adam's buggy change holding back my ability to push bug fixe...

I should apologise for this. I don't know the TCP stack well enough (obviously); I just sought to highlight a bug that I saw when I was hacking around for one of my own pet projects. I'll send a v2 patch in a second which should contain all the first, plus fixes at all the other places I can find that the contents of the header are calculated. (I've tested it between a couple of KVM instances, which is all the testing ability I have at the moment). You may well want to drop it and wait until some...

Three major portions to this change: 1) Add IW_EV_COMPAT_LCP_LEN, IW_EV_COMPAT_POINT_OFF, and IW_EV_COMPAT_POINT_LEN helper defines. 2) Delete iw_stream_check_add_*(), they are unused. 3) Add iw_request_info argument to iwe_stream_add_*(), and use it to size the event and pointer lengths correctly depending upon whether IW_REQUEST_FLAG_COMPAT is set or not. 4) The mechanical transformations to the drivers and wireless stack bits to get the iw_request_info passed down into the r...

From: Johannes Berg <johannes@sipsolutions.net> Likely yes, I guess that won't get hit with an allmodconfig build on sparc64 :( It would be really nice if we had some more compat layers so that the ps3 bus probing layer just nopped out but you could at least build test drivers on other platforms. --

From: "John W. Linville" <linville@tuxdriver.com> I'm not pulling this into my tree. I've already replied to that patch posting saying why I don't like this. Even if I found this change as the only way to go and therefore had to take it in, the commit log is way too terse about what the problem is. And it must describe the horrifics that are now necessary to include this file in userspace after the change. It needs to describe in detail what the conflicting types and definitions in the...

I've done a patch to myri10ge which enables the use of multiple transmit queues in our Linux driver using CONFIG_NETDEVICES_MULTIQUEUE netdev subqueues. Our current hardware uses multiple queues purely for increasing host parallelism, not priority/QOS. I'm looking for a way, beyond pktgen, to actually use any transmit queue other than 0 to increase parallelism. Ideally, we would like to support hashing connections on egress to the same tx/rx queue pair (and hence MSI-X irq) as our device will h...

This patch set modifies the HTB schedulers hysteresis mode. The HTB hysteresis is a hack to reduce the CPU load, it introduces significant jitter, enough to disturbe VoIP quality on e.g. ADSL. The first patch changes HTB_HYSTERESIS to default off. The second patch Change HTB_HYSTERESIS to a runtime parameter htb_hysteresis, adjustable via sys/module/sch_htb/parameters/htb_hysteresis.
