* ixgbe: Add support for new 82599 adapterDon Skidmore2011-05-153-0/+7
| | | | | | | | | This patch adds support for a new adapter in the 82599 family. Included in that support is a new media_type ixgbe_media_type_fiber_lco. Signed-of-by: Don Skidmore <donald.c.skidmore@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com>

* ixgbe: cleanup some minor issues in ixgbe_down()Alexander Duyck2011-05-151-18/+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.

* ixgbe: Merge over-temp task into service taskAlexander Duyck2011-05-152-36/+53
| | | | | | | | | This change merges the over-temp task into the service task. As a result all tasklets are finally combined into once single tasklet for easier management. Signed-off-by: Alexander Duyck <alexander.h.duyck@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com>
* ixgbe: Merge ATR reinit into the service taskAlexander Duyck2011-05-153-32/+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.

* ixgbe: merge reset task into service taskAlexander Duyck2011-05-152-24/+38
| | | | | | | | | | | This change is meant to further help to reduce possible configuration collisions between the various tasklets. This change combines the device reset with the service task. As a result it is now not possible to be updating the link on the device while also resetting the part.

* ixgbe: Merge watchdog functionality into service taskAlexander Duyck2011-05-152-166/+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.

* ixgbe: Combine SFP and multi-speed fiber task into single service taskAlexander Duyck2011-05-152-201/+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.

However, there are a couple of places where adapter->cmd_lock is taken with softirqs enabled, lockdep warns that a softirq that tries to take mc->mca_lock could happen while adapter->cmd_lock is held, leading to an AB-BA deadlock. I'm not sure if this is a real potential deadlock or not, but the simplest and best fix seems to be simply to make sure we take cmd_lock with spin_lock_irqsave() everywhere -- the places with plain spin_lock just look like oversights. The full enormous lockdep warning is: ========================================================= [ INFO: possible irq lock inversion dependency detected ] 2.6.39-rc6+ #1
