* ixgbe: Add FW detection and warning for 82599 SFP+ adaptersPeter P Waskiewicz Jr2009-06-07
| | | | | | | | | | | | | | | | 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.

* ixgbe: Add Flow Director init and modify functions for 82599Peter P Waskiewicz Jr2009-06-07
| | | | | | | | | | | | | This patch adds the functions for ixgbe to initialize Flow Director. It also has the function APIs to add Flow Director filters from the base driver. This also includes ATR, Application Targeted Routing, which is a feature set of Flow Director. This is the hash-based mechanism to automatically identify flows and add filters based on the hash, and direct the Rx of that flow back to that same CPU.

* ixgbe: Harden the 82599 multispeed fiber autotry mechanismPeter P Waskiewicz Jr2009-06-07
| | | | | | | | | | | | | | | 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.

* ixgbe: Change the 82599 PHY DSP restart logicPeter P Waskiewicz Jr2009-06-07
| | | | | | | | | | | | | 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.

* ixgbe: Remove device ID 0x10d8Peter P Waskiewicz Jr2009-05-26
| | | | | | | | | | | | 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.

* ixgbe: Add SAN MAC address to the RAR, return the address to DCBWaskiewicz Jr, Peter P2009-05-18
| | | | | | | | | | | | | | | | | 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.

* ixgbe: Add FCoE Storage MAC Address supportPJ Waskiewicz2009-05-18
| | | | | | | | | | | | | | | 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 Tx side offload features in base driver of 82599Yi Zou2009-05-17
| | | | | | | | | | | | | | | 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: Remove unnecessary PHY reset, properly identify multispeed fiber modulesPJ Waskiewicz2009-04-11
| | | | | | | | | | | | | | | | | | | | | | This patch does two things: 1) On 82599, the PHY is emedded in the MAC. On 82598, the SFP+ NIC has an external PHY. The reset in the SFP+ setup patch for 82598 is unnecessary on 82599, and adds extra dead time to device initialization. This removes that PHY reset for 82599 only. 2) On 82599, the SFP+ modules are multispeed fiber modules (10G/1G). We need to make sure to identify them properly for the remaining init sections to properly set them up.

* | ixgbe: Move PHY ops initialization to centralize bus accessesPJ Waskiewicz2009-04-11
|/ | | | | | | | | | | When PHY operations are determined, the PHY must be identified. This identification causes bus access, and should be contained within its own routines. This also helps the 82599 PHY init paths for both SFP+ and KX/KX4 devices to be easier to maintain.
