    "content": "Hi,\n\nChanges from v4:\n - Added a new bit to the MAC address filters internal representation\n to mean that some MAC address filters are steering filters (i.e. they\n direct traffic to queues);\n - And, this is only supported in i210;\n - Added a \"Known Issue\" section;\n\nChanges from v3:\n - Addressed review comments from Aaron F. Brown and\n   Jakub Kicinski;\n\nChanges from v2:\n - Addressed review comments from Jakub Kicinski, mostly about coding\n   style adjustments and more consistent error reporting;\n\nChanges from v1:\n - Addressed review comments from Alexander Duyck and Florian\n   Fainelli;\n - Adding and removing cls_flower filters are now proposed in the same\n   patch;\n - cls_flower filters are kept in a separated list from \"ethtool\"\n   filters (so that section of the original cover letter is no longer\n   valid);\n - The patch adding support for ethtool filters is now independent from\n   the rest of the series;\n\nKnown issue:\n - It seems that the the QSEL bits in the RAH registers do not have\n any effect for source address (i.e. steering doesn't work for source\n address filters), everything is pointing to a hardware (or\n documentation) issue;\n\nOriginal cover letter:\n\nThis series enables some ethtool and tc-flower filters to be offloaded\nto igb-based network controllers. This is useful when the system\nconfigurator want to steer kinds of traffic to a specific hardware\nqueue.\n\nThe first two commits are bug fixes.\n\nThe basis of this series is to export the internal API used to\nconfigure address filters, so they can be used by ethtool, and\nextending the functionality so an source address can be handled.\n\nThen, we enable the tc-flower offloading implementation to re-use the\nsame infrastructure as ethtool, and storing them in the per-adapter\n\"nfc\" (Network Filter Config?) list. But for consistency, for\ndestructive access they are separated, i.e. an filter added by\ntc-flower can only be removed by tc-flower, but ethtool can read them\nall.\n\nOnly support for VLAN Prio, Source and Destination MAC Address, and\nEthertype is enabled for now.\n\nOpen question:\n  - igb is initialized with the number of traffic classes as 1, if we\n  want to use multiple traffic classes we need to increase this value,\n  the only way I could find is to use mqprio (for example). Should igb\n  be initialized with, say, the number of queues as its \"num_tc\"?\n\nVinicius Costa Gomes (9):\n  igb: Fix not adding filter elements to the list\n  igb: Fix queue selection on MAC filters on i210\n  igb: Enable the hardware traffic class feature bit for igb models\n  igb: Add support for MAC address filters specifying source addresses\n  igb: Add support for enabling queue steering in filters\n  igb: Enable nfc filters to specify MAC addresses\n  igb: Add MAC address support for ethtool nftuple filters\n  igb: Add the skeletons for tc-flower offloading\n  igb: Add support for adding offloaded clsflower filters\n\n drivers/net/ethernet/intel/igb/e1000_defines.h |   2 +\n drivers/net/ethernet/intel/igb/igb.h           |  13 +\n drivers/net/ethernet/intel/igb/igb_ethtool.c   |  65 ++++-\n drivers/net/ethernet/intel/igb/igb_main.c      | 332 ++++++++++++++++++++++++-\n 4 files changed, 398 insertions(+), 14 deletions(-)\n\n--\n2.16.2"
