2014-03-14i40e/i40evf: Use dma_set_mask_and_coherentMitch Williams
In Linux 3.13, dma_set_mask_and_coherent was introduced, and we have been encouraged to use it. It simplifies the DMA mapping code a bit as well.

2014-03-14i40e/i40evf: Use correct number of VF vectorsMitch Williams
Now that the 2.4 firmware reports the correct number of MSI-X vectors, use this value correctly when communicating with the VF, and when setting up the interrupt linked list. The PF has always reported the correct number of MSI-X vectors, so we should never increment the value in the vf driver.

2014-03-14i40e: Bug fix for FDIR replay logicAnjali Singhai Jain
The FDIR replay logic was being run a little too soon (before the queues were enabled) and hence the tail bump was not effective till a later transaction happened on the queue.

2014-03-14i40e: Add code to handle FD table full conditionAnjali Singhai Jain
Add code to enforce the following policy: - If the HW reports filter programming error, we check if it's due to a full table. - If so, we go ahead and turn off new rule addition for ATR and then SB in that order. - We monitor the programmed filter count, if enough room is created due to filter deletion/reset, we then re-enable SB and ATR new rule addition.

2014-03-13sh_eth: update OF PHY registerationBen Dooks
If the sh_eth device is registered using OF, then the driver should call of_mdiobus_register() to register the PHYs described in the devicetree and then use of_phy_connect() to connect the PHYs to the device. This ensures that any PHYs registered in the device tree are appropriately connected to the parent devices nodes so that the PHY drivers can access their OF properties.

2014-03-13eth: fec: Fix lost promiscuous mode after reconnecting cableStefan Wahren
If the Freescale fec is in promiscuous mode and network cable is reconnected then the promiscuous mode get lost. The problem is caused by a too soon call of set_multicast_list to re-enable promisc mode. The FEC_R_CNTRL register changes are overwritten by fec_restart. This patch fixes this by moving the call behind the init of FEC_R_CNTRL register in fec_restart. Successful tested on a i.MX28 board.

Tom Herbert provides changes to e1000e, igb and ixgbe to call skb_set_hash() to set the hash and its type in an skbuff. Carolyn provides a fix for igb where using ethtool for EEE settings, which was not working correctly. Jacob provides some trivial cleanups and fixes for ixgbe which mainly dealt with the file headers. Julia Lawall provides a one fix for ixgbevf where the driver did not need to adjust the power state on suspend, so the call to pci_set_power_state() in the resume function was a no-op. v2: - dropped patches 4-6 from original series which implemented debugfs for igb from Carolyn based on feed back from David Miller and Or Gerlitz ==================== Signed-off-by: David S.
