From: Jesse Brandeburg <jesse.brandeburg@intel.com> it was pointed out on the list that ixgbe was failing when using 64kB pages and large 16kB MTU. since with a 64kB PAGE_SIZE MAX_SKB_FRAGS = 3, the way the driver was configuring page usage was assuming 2kB is half a page, and was only ever dmaing that much data to a half page. (16kB - header size) / 2048 = 7 or 8 pages, which would far exceed 3 adjust the driver to account for these large pages, the hardware can support DMA to up to ...

I was investigating behaviour of the TCP/IP stacks and noticed that Linux has a peculiarity. When a packet is received with the correct sequence number but incorrect acknowledgement number (in my tests, it was higher than the correct acknowledgement number), the stack accepts the packet as a valid packet and passes the data up to the application (I do not know whether the ack information is accepted). According to the list of tests described here in the TCP RFC 793 [1], accepting a packet ...

Point taken. I just gave it a try with 2.6.29-rc6 and the problem persists. --

Hi Dave, the following patches contain netfilter fixes for 2.6.29: - a typo fix in a ICMPv6 conntrack log message from Eric Leblond - a fix for nfnetlink_log per-rule threshold overrides. Currently the rule always wins because of the defaults, which is not intended. Also from Eric. - a fix for the nfnetlink_log default timeout units from Eric. The kernel uses 10ms units, the default is specified in HZ. - a fix to avoid conntrack event delivery for untracked connections - a ...

Hi, Well, I guess it's a bit like a proof of concept rather than an applicable patch? :-) And it's based on "chan" branch. This isn't good, the "chan" isn't yet ready to go upstream, the interface isn't yet stable. It's really experimental, based on undocumented behaviour etc. Do you need the "channelized" feature? If not, perhaps you should stick to HDLC-only David's net-next? Same here. This only needs a tiny change, increasing the number of HDLC devices to 2 or 4 (for each ...

(note, the standalone mail of this bug entry did not make it out for some reason.)

This adds support to Linux for using virtio between two computers linked by a PCI interface. This allows the use of virtio_net to create a familiar, fast interface for communication. It should be possible to use other virtio devices in the future, but this has not been tested.

The driver is trivial to port ...

Automatic restart is already support by this patch series but we do not use the watchdog, because it would trigger on normal transmit timeouts as well. But maybe we can suppress them by fiddling with the watchdog's OK, it also depends on what we would like the tool finally to perform, apart from setting and getting device properties. On idea is to move the rather heavy calculation of bit-timing parameters out of the kernel to the user-space configuration tool. Wolfgang. --
