This series contains updates to i40e and i40evf. The theme behind this series is code reduction, yeah! Jesse provides most of the changes starting with a refactor of the interpretation of a tunnel which lets us start using the hardware's parsing. Removed the packet split receive routine and ancillary code in preparation for the Rx-refactor. The refactor of the receive routine, aligns the receive routine with the one in ixgbe which was highly optimized. The hardware supports a 16 byte descriptor for receive, but the driver was never using it in production. There was no performance benefit to the real driver of 16 byte descriptors, so drop a whole lot of complexity while getting rid of the code. Fixed a bug where while changing the number of descriptors using ethtool, the driver did not test the limits of the system memory before permanently assuming it would be able to get receive buffer memory.
Mitch fixes a memory leak of one page each time the driver is opened by allocating the correct number of receive buffers and do not fiddle with next_to_use in the VF driver. Arnd Bergmann fixed a indentation issue by adding the appropriate curly braces in i40e_vc_config_promiscuous_mode_msg(). Julia Lawall fixed an issue found by Coccinelle, where i40e_client_ops structure can be const since it is never modified.
