2009-06-08tun: Optimise handling of bogus gso->hdr_lenHerbert Xu
As all current versions of virtio_net generate a value for the header length that's too small, we should optimise this so that we don't copy it twice. This can be done by ensuring that it is at least as large as the place where we'll write the checksum. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S.

2009-06-08virtio_net: Set correct gso->hdr_lenHerbert Xu
Through a bug in the tun driver, I noticed that virtio_net is producing bogus hdr_len values. In particular, it only includes the IP header in the linear area, and excludes the entire TCP header. This causes the TCP header to be copied twice for each packet. (The bug omitted the second copy :) This patch corrects this.

2009-06-08qlge: Fix timeout on firmware mailbox commands.Ron Mercer
Some firmware mailbox commands require the firmware to communicate with the FCoE driver running on another PCI function. This can potentially take several seconds. This wait is done in process context only. Signed-off-by: Ron Mercer <ron.mercer@qlogic.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-06-08qlge: Fix timeout on indexed register wait.Ron Mercer
There are 8 banks of 'sub-registers' each of which are accessed through address/data register pair. An example would be reading flash or the xgmac. Accessing these require the driver to wait for a ready bit before writing the address and then accessing the data. This patch increases the timeout to 100us to prevent timeouts that have been seen on some platforms. These register are accessed in process context only.

2009-06-08qlge: Fix bug in MTU setting process.Ron Mercer

2009-06-08qlge: Fix bug in firmware event handler.Ron Mercer
Each firmware mailbox command can have a different number of valid data elements. When waiting for a mailbox command to complete it the process passes it's element count and waits for the completion. It is possible that while waiting an unrelated firmware async event (AE) can arrive. When this happens, the handler will over write the element count with the value for the newly arrived AE. This can cause the mailbox command to not get all of it's data. This patch restores original mailbox count at the end of the handler.

2009-06-07ixgbe: Add FW detection and warning for 82599 SFP+ adaptersPeter P Waskiewicz Jr
82599 has a FW running that helps manage the internal SFI PHY. There are also a number of pre-production samples of these SFI-based devices in the field. This patch adds a check to look for the firmware running on all SFP+ based adapters, and displays a warning to the system log if a pre-production adapter is identified. The driver will continue loading though, with no functional degradation. Also remove an old function prototype from ixgbe_82599.c that isn't being used.

2009-06-07ixgbe: move tx processing into NAPI contextAlexander Duyck
This patch moves the tx cleanup processing out of the MSI-X interrupt processing and gives it it's own napi routine.

2009-06-07ixgbe: use rx_buffer_info->dma instead of nr_frags to determine skb unmapAlexander Duyck
This patch changes the driver so that it uses rx_buffer_info->dma to determine if it needs to unmap the page instead of sh_info->nr_frags.

2009-06-07ixgbe: Harden the 82599 multispeed fiber autotry mechanismPeter P Waskiewicz Jr
82599 supports multispeed fiber optical modules (10Gbps/1Gbps). Some scenarios can cause the autotry mechanism to not negotiate link properly. What needs to happen is the driver must flap the Tx laser to induce an Rx Loss of Signal on the link partner. This will restart the autotry mechanism to get link into a known state. The software definable pin (SDP) 3 on the 0x10fb NIC is wired to cause a Tx LOS event, which triggers the Rx LOS we require.

2009-06-07ixgbe: Change the 82599 PHY DSP restart logicPeter P Waskiewicz Jr
When reprogramming the 82599 analog PHY to either SFI optical or Direct Attach Twinax, we need to restart the DSP in the PHY. The current method can cause contention with our FW which is managing PHY state, and will cause unexpected link flaps. This patch fixes the DSP restart by issuing an AN_RESTART in the MAC, which will properly propagate the DSP restart to the PHY. This ensures we don't collide with the FW.

2009-06-04iwl3945/iwlwifi: fix led bug when SW rfkillAbhijeet Kolekar
Patch fixes the bug at http://www.intellinuxwireless.org/bugzilla/show_bug.cgi?id=1903 when SW rfkill is invoked by 'iwconfig txpower off', the existing connection disassociates and led off command is sent to the device which returns error as rfkill is 'true'. Patch fixes this by just avoiding sending the led off/on command when disassociated. The main purpose of the led_disassociate callback is to start or stop the blinking. There are three states in led 1) Always on when radio is on 2) Always off when radio is off 3) blink when associated and if there is some traffic. In this callback 'allow_blinking' needs to be set false when associated, as LED will be always on.

2009-06-03tun: Only wake up writersHerbert Xu
When I added socket accounting to tun I inadvertently introduced spurious wake-up events that kills qemu performance. The problem occurs when qemu polls on the tun fd for read, and then transmits packets. For each packet transmitted, we will wake up qemu even if it only cares about read events. Now this affects all sockets, but it is only a new problem for tun. So this patch tries to fix it for tun first and we can then look at the problem in general.
