* ixgbe: Add FCoE Storage MAC Address supportPJ Waskiewicz2009-05-171-0/+48
| | | | | | | | | | | | | | | This patch implements the Storage Address entrypoint from the net device. It will read the SAN MAC addresses from the EEPROM of the 82599 hardware, and make them available to the FCoE stack through the net device. Also, add/del the SAN MAC address to the netdev dev_addr_list via the kernel api dev_addr_add()/dev_addr_del() when there is a valid SAN MAC supported by the HW.

* ixgbe: Implement FCoE Rx side large receive offload feature to 82599Yi Zou2009-05-171-0/+16
| | | | | | | | | | | | | | | This patch implements the FCoE Rx side offload feature in ixgbe_main.c to 82599 using the Rx offload infrastructure code added in the previous patch. The large receive offload by Direct Data Placement (DDP) for FCoE is achieved by implementing the ndo_fcoe_ddp_setup and ndo_fcoe_ddp_done in net_device_ops via netdev. It is up to the ULD, i.e., fcoe and libfc to query and setup large receive offload accordingly through the corresponding netdev upon creating fcoe instances.

* ixgbe: Implement FCoE Tx side offload features in base driver of 82599Yi Zou2009-05-171-19/+85
| | | | | | | | | | | | | | | This patch implements the FCoE Tx side offload features in ixgbe_main.c to 82599 using the Tx offload infrastructure code added in the previous patch. This is achieved by the calling the FCoE Sequence Offload (FSO) function ixgbe_fso() on the transmit path of ixgbe. This patch also includes an EEPROM check to make sure the NIC we're loading on is an offload-enabled SKU.

* ixgbe: fix failing to log fan failuresDon Skidmore2009-05-071-2/+26
| | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | Traditionally Intel based NIC drivers request I/O port even though it doesn't need that really. Intel PCIE 10Gb driver (ixgbe) also requests I/O port but it doesn't need it either.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch enables hardware receive side coalescing for 82599 hardware. 82599 can merge multiple frames from the same TCP/IP flow into a single structure that can span one ore more descriptors. The accumulated data is arranged similar to how jumbo frames are arranged with the exception that other packets can be interlaced inbetween. To overcome this issue a next pointer is included in the written back descriptor which indicates the next descriptor in the writeback sequence. This feature sets the NETIF_F_LRO flag and clearing it via the ethtool set flags operation will also disable hardware RSC.

* ixgbe: Fixup the watchdog interrupt scheduling on 82599Jesse Brandeburg2009-03-201-32/+81
| | | | | | | | | | | | | | The watchdog will schedule an interrupt to help make sure queues are cleaned in the case when an interrupt is missed, most likely due to very high load. On 82599, there are extra interrupt registers to account for the larger number of MSI-X vectors (64 total for 82599 vs. 18 total for 82598). These must be taken into account when performing this operation in the watchdog.

| | | | | | | | | | | | | | | | | | | | | | | | | | Multiple unicast address support appears to have been broken with the change to support net_device_ops. This a regression from 2.6.28 to 2.6.29. I'm not 100% on whether ndo_set_multicast_list can be NULL after this or not. If ndo_set_rx_mode is set everything _should_ be using it.

| | | | | | | | | | | | | | | | | | | | | | | | The Tx DMA unit should be disabled when bringing the device down. Also, the KX4 device with 82599 supports WoL, so we should clear the Wake Up Status (WUS) after a PCIe slot reset.

* | ixgbe: Add a few safety nets for register writes and descriptor cleanupsJesse Brandeburg2009-03-141-6/+12
| | | | | | | | | | | | | | | | | | | | | | | | There are possible times that a driver may fail to completely initialize, due to a buggy platform or a buggy kernel. In those cases, we'd rather fail gracefully instead of a panic. Add a few safety checks to some critical paths to try and prevent a panic in these corner-case situations.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This cleans up the following pieces of the Rx initialization path: - Enable the ECC memory fault interrupt in OTHER causes. - Fix an 82598 initialization of RDRXCTL when depending on RSS and VMDq to be enabled. We don't need these features enabled to safely set the MVMEN bit to allow multiple SRRCTL register mappings into the RXDCTL registers. - Fix the RSS initialization path to not stomp on DCB accidentally. When configuring the MRQC (multiple Rx queue contol) register, we want to make sure we only OR in features as necessary, instead of full assignment.

* | ixgbe: Fix the Tx clean logic to return proper statusJesse Brandeburg2009-03-141-9/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The Tx accounting when cleaning during NAPI was not completely properly. We should use the work_limit to determine when to finish cleaning, and use the same to return the cleaned status. The impact of running like this causes the NAPI clean for this Tx to get stuck in a scheduling loop, and can result in Tx not getting cleaned, ending with a Tx hang and device reset.
