2011-05-14ixgbe: cleanup some minor issues in ixgbe_down()Alexander Duyck1-18/+16
This patch cleans up two minor issues in ixgbe_down. Specifically it addresses the fact that the VFs should not be pinged until after interrupts are disabled otherwise they might still get a response. It also drops the use of the txdctl temporary variable since the only bit we should be writing to the TXDCTL registers during a shutdown is the flush bit.

2011-05-14ixgbe: Merge over-temp task into service taskAlexander Duyck2-36/+53

2011-05-14ixgbe: Merge ATR reinit into the service taskAlexander Duyck3-32/+37
This change merges the ATR table reinitialization into the service task. This is yet another opportunity to avoid any race conditions as we don't want to be attempting to reinitialize the table during a possible reset. In addition this change adds a counter for table reinitialization so that it can be tracked as part of the regular statistics.

2011-05-14ixgbe: Merge watchdog functionality into service taskAlexander Duyck2-166/+200
This patch is meant to merge the functionality of the ixgbe watchdog task into the service task. By doing this all link state functionality will be controlled by a single task. As a result the reliability of the interface will be improved as the likelihood of any race conditions is further reduced.

2011-05-14ixgbe: Combine SFP and multi-speed fiber task into single service taskAlexander Duyck2-201/+213
This change is meant to address several race conditions with multi-speed fiber SFP+ modules in 82599 adapters. Specifically issues have been seen in which both the SFP configuration and the multi-speed fiber configuration are running simultaneously which will result in the device getting into an erroneous link down state.

PCIe connections should be expressed as GT/s (GigaTransfers per second) instead of the current Gb/s (Gigabits per second). In addition, it is incorrect because (due to PCIe gen 1 & 2 having a 20% overhead) the actually data rate, when expressed in Gb/s, is only 80% of the rate of GT/s.

2011-05-04ixgbe: improve EEPROM read/write operationsEmil Tantilov7-100/+465
Introduce buffered read/writes which greatly improves performance on parts with large EEPROMs. Previously reading/writing a word requires taking/releasing of synchronization semaphores which adds 10ms to each operation. The optimization is to read/write in buffers, but make sure the semaphore is not held for >500ms according to the datasheet. Since we can't read the EEPROM page size ixgbe_detect_eeprom_page_size() is used to discover the EEPROM size when needed and keeps the result in word_page_size for the rest of the run time. Use buffered reads for ethtool -e. Signed-off-by: Emil Tantilov <emil.s.tantilov@intel.com> Tested-by: Evan Swanson <evan.swanson@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com>

2011-04-29ethtool: cosmetic: Use ethtool ethtool_cmd_speed APIDavid Decotigny1-4/+4
This updates the network drivers so that they don't access the ethtool_cmd::speed field directly, but use ethtool_cmd_speed() instead. For most of the drivers, these changes are purely cosmetic and don't fix any problem, such as for those 1GbE/10GbE drivers that indirectly call their own ethtool get_settings()/mii_ethtool_gset(). The changes are meant to enforce code consistency and provide robustness with future larger throughputs, at the expense of a few CPU cycles for each ethtool operation.

2011-04-27ixgbe: do not clear FCoE DDP error status for received ABTSYi Zou1-2/+2
The ddp->err is initialized to be 1 to make sure outstanding DDP context is guaranteed to be invalidated when HW is not auto-invalidating it. However, in case of receiving ABTS response for a DDPed I/O, the ddp->err was cleared, bypassing the invalidating of the DDP context from upper protocol stack when ixgbe_fcoe_ddp_put() is called.

The X540 device has a smaller packet buffer but the DCB configuration never took this into account. Under stress this can result in the DMA engine hanging and TX Unit hang occurring to reset the device. This patch reworks the packet buffer allocation routine used for DCB on 82599 and X540 devices to account for RX packet buffer sizes. This fixes the immediate hang. We should consolidate the various hardware specific routines for configuring features into a single routine. This will make it much harder to miss feature cases like this.

The rate limitation can be configured only when the link is up and the link speed is 10Gb. The rate limit value can be 0 or ranged between 11 and actual link speed measured in Mbps. A value of '0' disables the rate limit for this specific VF. iproute2 usage will be 'ip link set ethX vf Y rate Z'. After the command is made, the rate will be changed instantly.
