* i40e: clean up Tx fast pathAlexander Duyck2013-10-091-1/+0
| | | | | | | | | | | | | | | Sync the fast path for i40e_tx_map and i40e_clean_tx_irq so that they are similar to igb and ixgbe. - Only update the Tx descriptor ring in tx_map - Make skb mapping always on the first buffer in the chain - Drop the use of MAPPED_AS_PAGE Tx flag - Only store flags on the first buffer_info structure Signed-off-by: Alexander Duyck <alexander.h.duyck@intel.com> Signed-off-by: Jesse Brandeburg <jesse.brandeburg@intel.com> Tested-by: Kavindya Deegala <kavindya.s.deegala@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com>
* i40e: Cleanup Tx buffer info layoutAlexander Duyck2013-10-091-7/+6
| | | | | | | | | | | | | - drop the mapped_as_page u8 from the Tx buffer info as it was unused - use the DMA unmap accessors for Tx DMA - replace checks of DMA with checks of the unmap length to verify if an unmap is needed - update the Tx buffer layout to make it consistent with igb, ixgbe Signed-off-by: Alexander Duyck <alexander.h.duyck@intel.com> Signed-off-by: Jesse Brandeburg <jesse.brandeburg@intel.com> Tested-by: Kavindya Deegala <kavindya.s.deegala@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com>
* i40e: Drop unused completed statAlexander Duyck2013-10-091-1/+0
| | | | | | | | | | | | | The Tx "completed" stat was part of the original rewrite for detecting Tx hangs. However some time ago in ixgbe I determined that we could just use the packets stat instead. Since then this stat was removed from ixgbe and it serves no purpose in i40e so it can be dropped.

* i40e: driver core headersJesse Brandeburg2013-09-111-0/+259
This patch contains the main driver header files, containing structures and data types specific to the linux driver. i40e_osdep.h contains some code that helps us adapt our OS agnostic code to Linux.
