| * | ixgbevf: Fix AIM (Adaptive Interrupt Moderation)Greg Rose2012-09-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While fixing up a patch from Alex Duyck to use q_vectors in ring containers to update the ITR I bungled it and missed actually updating the counters in the ring container q_vectors. This patch fixes my mistake and makes interrupt moderation actually work. Signed-off-by: Greg Rose <gregory.v.rose@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com>

| * | ixgbevf: Fix code for handling timeoutAlexander Duyck2012-09-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The VF driver was not designed to correctly handle a message timeout. As a result it is possible for one bad message to invalidate all messages following it until the part is reset. Instead we should copy the example in igbvf of how to handle a mailbox event and message timeout.

| * | igb: Use dma_unmap_addr and dma_unmap_len definesAlexander Duyck2012-09-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change is meant to improve performance on systems that do not require the DMA unmap calls. On those systems we do not need to make use of the unmap address for Tx or the unmap length so we can drop both thereby reducing the size of the Tx buffer info structure. In addition I have changed the logic to check for unmap length instead of unmap address when checking to see if a buffer needs to be unmapped from DMA use. The reasons for this change is that on some platforms it is possible to receive a valid DMA address of 0 from an IOMMU.

| * | igb: Simplify how we populate the RSS keyAlexander Duyck2012-09-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of storing the RSS key as a character array we can simplify the configuration by making it a u32 array. This allows us to just write one value per register without any unnecessary operations to construct the value. This change will produce the same exact key, the only difference is that I translated the u8 array to a u32 array which will be correctly ordered on writes to hardware by the cpu_to_le32 operations that are built into the writel calls.

| * | igb: Change how we populate the RSS indirection tableAlexander Duyck2012-09-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch cleans up our RSS indirection table configuration so that we generate the same table regardless of CPU endianness. In addition it changes the table setup so that instead of doing a modulo based setup it is instead a divisor based setup. The advantage to this is that we should be able to take the Rx hash and compute the Rx queue with very little CPU overhead if needed.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change makes it so that Tx cleanup is done in a do/while loop instead of a for loop. The main motivation behind this is the fact that we should never be invoked with a budget less than 1 so we can skip checking the budget before processing the first descriptor.

| | | | | | | | | | | | | | | | | | | | | | | | | | | Early release of i210 devices had the loopback test of the ethtool self-test disabled. This patch enables the loopback test for i210 devices.

| | * | ixgbevf: Cleanup handling of configuration for jumbo framesAlexander Duyck2012-08-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change moves the code for notifying the PF of the VF maximum packet size into the vf.c file. The main motivation behind this is that the vf.c file is supposed to contain all of the messages used when communicating with the PF. In addition it creates a separate function for setting the Rx buffer size so that we have on centralized area to review what buffer sizes will be requested by the VF.
