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.

2009-05-26ixgbe: Remove device ID 0x10d8Peter P Waskiewicz Jr
Device ID 0x10d8 is the default silicon device ID for 82599. However, the device will not be functional without an EEPROM, so we want to prevent the driver from loading on the device. Otherwise, the driver will load, but no PHY setup or PCIe setup will occur, causing the device to be unusable. To prevent users from encountering this, just remove the device ID.

82599 supports using either link flow control or priority flow control when in DCB mode. The dcbnl interface already supports sending down configurations through rtnetlink that can enable LFC when DCB is enabled, so the driver should take advantage of this. 82598 does not support using LFC when DCB is enabled, so explicitly disable it when we're in DCB mode. This means we always run in PFC mode when DCB is enabled.

2009-05-17ixgbe: Add SAN MAC address to the RAR, return the address to DCBWaskiewicz Jr, Peter P
After acquiring the SAN MAC address from the EEPROM, we need to program it into one of the RARs. Also, DCB will use this MAC address to run DCBX commands, so it doesn't have to play musical MAC addresses when things like bonding enter the picture. So we need to return the MAC address through the netlink interface to userspace. This also moves the init_rx_addrs() call out of start_hw() and into reset_hw(). We shouldn't try to read any of the RAR information before initializing our internal accounting of the RAR table, which was what was happening.

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.

2009-04-20ixgbe: fix link down initial stateJesse Brandeburg
As reported by Andrew Lutomirski <amluto@gmail.com> All the intel wired ethernet drivers were calling netif_carrier_off and netif_stop_queue (or variants) before calling register_netdevice This is incorrect behavior as was pointed out by davem, and causes ifconfig and friends to report a strange state before first link after the driver was loaded, since without a netif_carrier_off, the stack assumes carrier_on, but before register_netdev, netlink messages are not sent out telling link state. This apparently confused *some* versions of networkmanager.
