2009-06-08net: skb_shared_info optimizationEric Dumazet
skb_dma_unmap() is quite expensive for small packets, because we use two different cache lines from skb_shared_info. One to access nr_frags, one to access dma_maps[0] Instead of dma_maps being an array of MAX_SKB_FRAGS + 1 elements, let dma_head alone in a new dma_head field, close to nr_frags, to reduce cache lines misses.

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: 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.

2009-05-29net: convert unicast addr listJiri Pirko
This patch converts unicast address list to standard list_head using previously introduced struct netdev_hw_addr. It also relaxes the locking. Original spinlock (still used for multicast addresses) is not needed and is no longer used for a protection of this list. All reading and writing takes place under rtnl (with no changes). I also removed a possibility to specify the length of the address while adding or deleting unicast address. It's always dev->addr_len. The convertion touched especially e1000 and ixgbe codes when the change is not so trivial.

2009-05-26ixgbe: fix 82598 SFP initialization after driver load.Don Skidmore
If we loaded the driver with out a SFP module plugged in it would leave it in a state that make it later unable to link when a module was plugged in. This patch corrects that by: ixgbe_probe() - moving the check for IXGBE_ERR_SFP_NOT_PRESENT from after get_invariants() to after reset_hw() as now reset_hw() is where this condition will be indentified. ixgbe_reset_hw_82598() - Enable this function to now return IXGBE_ERR_SFP_NOT_PRESENT. ixgbe_identify_sfp_module_generic() - This where the lack of SFP module is detected. Modifications are added to allow a different return value for modules that just haven't been plugged in yet. Other functions were updated to allow correct logging.

2009-05-17ixgbe: Add FCoE feature code to 82599Yi Zou
This adds the FCoE feature code ixgbe_fcoe.c to 82599. For a start, this patch only adds ixgbe_configure_fcoe() to configure related register for FCoE to 82599. In patches that follow, I will be adding more functions to ixgbe_fcoe.c to add support of FCoE offload features to 82599.

2009-05-17ixgbe: Add FCoE feature header to 82599Yi Zou
This adds the FCoE feature header ixgbe_fcoe.h to 82599. This header includes the defines and structures required by the ixgbe driver to support various offload features in 82599 for Fiber Channel over Ethernet (FCoE). These offloads features include Fiber Channel CRC calculation, FCoE SOF/EOF auto insertion, FCoE Sequence Offload (FSO) for large send, and Direct Data Placement (DDP) for large receive.

2009-05-07ixgbe: fix failing to log fan failuresDon Skidmore
We weren't logging the 82598AT fan failure if it occurred before (ixgbe_open) as we hadn't sent up to catch the interrupt that event caused. This patch checks for this failure in: ixgbe_probe - So we can log the failure asap. We check right after we set up the adapter->flags, which is when we know that we have a fan. ixgbe_up_complete - To catch failures that may have happened between probe and when we set up the interrupt that would normally detect the fan failure. To enable all of this we need to initialize the adapter flag with IXGBE_FLAG_FAN_FAIL_CAPABLE when the NIC contained a fan.
