This series contains updates to i40e and i40evf only. Preethi changes the default driver mode of operation to descriptor write-back for VF.
Alex cleans up and addresses several issues in the way that i40e handles private flags. Modifies the driver to use the length of the packet instead of the DD status bit to determine if a new descriptor is ready to be processed. Refactors the driver by pulling the code responsible for fetching the receive buffer and synchronizing DMA into a single function. Also pulled the code responsible for handling buffer recycling and page counting and distributed it through several functions, so we can commonize the bits that handle either freeing or recycling the buffers. Cleans up the code in preparation for us adding support for build_skb(). Changed the way we handle the maximum frame size for the receive path so it is more consistent with other drivers. Paul enables XL722 to use the direct read/write method since it does not support the AQ command to read/write the control register. Christopher fixes a case where we miss an arq element if a new one is added before we enable interrupts and exit the loop. Jake cleans up a pointless goto statement. Also cleaned up a flag that was not being used. Carolyn does round 2 for adding a delay to the receive queue to accommodate the hardware needs. The following are changes since commit 0e42c72195cc1a6f7461bfc48b32dce29e1677f7: Merge branch 'netconf-delnetconf' and are available in the git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/next-queue 40GbE Alexander Duyck (7): i40e: Clean up handling of private flags i40e/i40evf: Use length to determine if descriptor is done i40e/i40evf: Pull code for grabbing and syncing rx_buffer from fetch_buffer i40e/i40evf: Pull out code for cleaning up Rx buffers i40e/i40evf: Break i40e_fetch_rx_buffer up to allow for reuse of frag code i40e/i40evf: Add legacy-rx private flag to allow fallback to old Rx flow i40e/i40evf: Change the way we limit the maximum frame size for Rx Christopher N Bednarz (1): i40e: Check for new arq elements before leaving the adminq subtask loop Jacob Keller (2): i40e: remove a useless goto statement i40e: remove FDIR_REQUIRES_REINIT driver flag Paul M Stillwell Jr (1): i40e: use register for XL722 control register read/write Preethi Banala (1): i40evf: enforce descriptor write-back mechanism for VF Wyborny, Carolyn (1): i40e: fix for queue timing delays drivers/net/ethernet/intel/i40e/i40e.h | 10 +- drivers/net/ethernet/intel/i40e/i40e_common.c | 8 +- drivers/net/ethernet/intel/i40e/i40e_ethtool.c | 192 ++++++++----- drivers/net/ethernet/intel/i40e/i40e_main.c | 42 +-- drivers/net/ethernet/intel/i40e/i40e_txrx.c | 249 ++++++++-------- drivers/net/ethernet/intel/i40e/i40e_txrx.h | 4 +- drivers/net/ethernet/intel/i40evf/i40e_common.c | 8 +- drivers/net/ethernet/intel/i40evf/i40e_txrx.c | 312 +++++++++------------ drivers/net/ethernet/intel/i40evf/i40e_txrx.h | 18 +- drivers/net/ethernet/intel/i40evf/i40evf.h | 6 +- drivers/net/ethernet/intel/i40evf/i40evf_ethtool.c | 104 +++++++ drivers/net/ethernet/intel/i40evf/i40evf_main.c | 16 +- .../net/ethernet/intel/i40evf/i40evf_virtchnl.c | 18 +- 13 files changed, 559 insertions(+), 428 deletions(-) -- 2.12.0
