Merge branch 'master' of git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/net-next
Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2014-11-20 This series contains updates to ixgbevf, i40e and i40evf. Emil updates ixgbevf with much of the work that Alex Duyck did while at Intel. First updates the driver to clear the status bits on allocation instead of in the cleanup routine, this way we can leave the recieve descriptor rings as a read only memory block until we actually have buffers to give back to the hardware. Clean up ixgbevf_clean_rx_irq() by creating ixgbevf_process_skb_field() to merge several similar operations into this new function. Cleanup temporary variables within the receive hot-path and reducing the scope of variables that do not need to exist outside the main loop. Save on stack space by just storing our updated values back in next_to_clean instead of using a stack variable, which also collapses the size the function. Improve performace on IOMMU enabled systems and reduce cache misses by changing the basic receive patch for ixgbevf so that instead of receiving the data into an skb, it is received into a double buffered page. Add netpoll support by creating ixgbevf_netpoll(), which is a callback for .ndo_poll_controller to allow for the VF interface to be used with netconsole. Mitch provides several cleanups and trivial fixes for i40e and i40evf. First is a fix the overloading of the msg_size field in the arq_event_info struct by splitting the field into two and renaming to indicate the actual function of each field. Updates code comments to match the actual function. Cleanup several checkpatch.pl warnings by adding or removing blank lines, aligning function parameters, and correcting over-long lines (which makes the code more readable). Shannon provides a patch for i40e to write the extra bits that will turn off the ITR wait for the interrupt, since we want the SW INT to go off as soon as possible. v2: updated patch 07 based on feedback from Alex Duyck by - adding pfmemalloc check to a new function for reusable page - moved atomic_inc outside of #if/else in ixgbevf_add_rx_frag() - reverted the removal of the API check in ixgbevf_change_mtu() ==================== Signed-off-by: David S.
