2007-10-10pasemi_mac: Clean TX ring in pollOlof Johansson
Unfortunately there's no timeout for how long a packet can sit on the TX ring after completion before an interrupt is generated, and we want to have a threshold that's larger than one packet per interrupt. So we have to have a timer that occasionally cleans the TX ring even though there hasn't been an interrupt. Instead of setting up a dedicated timer for this, just clean it in the NAPI poll routine instead.

2007-10-10pasemi_mac: Fix TX ring wrap checkingOlof Johansson
The old logic didn't detect full (tx) ring cases properly, causing overruns and general badness. Clean it up a bit and abstract out the ring size checks, always making sure to leave 1 slot open. Signed-off-by: Olof Johansson <olof@lixom.net> Signed-off-by: Jeff Garzik <jeff@garzik.org>

2007-10-10pasemi_mac: Stop using the pci config space accessors for register read/writesOlof Johansson
Move away from using the pci config access functions for simple register access. Our device has all of the registers in the config space (hey, from the hardware point of view it looks reasonable :-), so we need to somehow get to it. Newer firmwares have it in the device tree such that we can just get it and ioremap it there (in case it ever moves in future products). For now, provide a hardcoded fallback for older firmwares.

Use the kernel interfaces for advanced error reporting. This should be cleaner and clear up errors on boot. For those systems with busted BIOS's that don't correctly support mmconfig, advanced error reporting will be disabled.

2007-10-10cxgb3 - Expose HW memory page infoDivy Le Ray

2007-10-10ibmveth: Enable TCP checksum offloadBrian King
This patchset enables TCP checksum offload support for IPV4 on ibmveth. This completely eliminates the generation and checking of the checksum for packets that are completely virtual and never touch a physical network. A simple TCP_STREAM netperf run on a virtual network with maximum mtu set yielded a ~30% increase in throughput. This feature is enabled by default on systems that support it, but can be disabled with a module option.

2007-10-10[E1000E]: New pci-express e1000 driver (currently for ICH9 devices only)Auke Kok
This driver implements support for the ICH9 on-board LAN ethernet device. The device is similar to ICH8. The driver encompasses code to support 82571/2/3, es2lan and ICH8 devices as well, but those device IDs are disabled and will be "lifted" from the e1000 driver over one at a time once this driver receives some more live time. Changes to the last snapshot posted are exclusively in the internal hardware API organization.

2007-10-10[PATCH] libertas: reorganize and simplify init sequenceDan Williams
This patch moves all firmware load responsibility into the interface-specific code and gets rid of the firmware pointer in the generic card structure. It also removes 3 fairly unecessary callbacks: hw_register_dev, hw_unregister_dev, and hw_prog_firmware. It also makes the init sequence from interface probe functions more logical, as there are paired add/remove and start/stop calls into generic libertas code. Because the USB driver code uses the same TX URB callback for both firmware upload (where the generic libertas structure isn't initialized yet) and for normal operation (where it is), some bits of USB code have to deal with 'priv' being NULL. All USB firmware upload bits have been changed to not require 'priv' at all, but simply the USB card structure. Signed-off-by: Dan Williams <dcbw@redhat.com> Signed-off-by: John W.

2007-10-10[PATCH] zd1211rw: consistent handling of ZD1211 specific ratesUlrich Kunitz
As pointed out by Daniel Drake, the zd1211rw driver used several different rate values and names throughout the driver. He has written a patch to change it and tweaked it after some pretty wild ideas from my side. But the discussion helped me to understand the problem better and I think I have nailed it down with this patch. A zd-rate will consist from now on of a four-bit "pure" rate value and a modulation type flag as used in the ZD1211 control set used for packet transmission. This is consistent with the usage in the zd_rates table. If possible these zd-rates should be used in the code.
