The\nidea is that the more TSN specific code will live here, in the future\nthis will include frame-preemption support, and CBS (formerly Qav)\nsupport.\n\nThe current support has a few limitations:\n - because the BASET registers can only be written once per reset,\n when removing taprio or ETF, we force the NIC to reset;\n - In part because of the above limitation, we don't support changing\n schedules;\n - The way the registers for the schedule are organized, each queue\n can only be opened and closed once per cycle, so some schedules\n provided by the user are going to be rejected by the driver;\n\nFuture improvements:\n - When configuring a Qbv cycle, when we detect that a queue would\n stay open for two intervals, we could want to merge them;\n - More testing with taprio and ETF together, when ETF is installed\n under taprio (when using them separately, it works fine);\n\n--\nCheers,\n\nVinicius Costa Gomes (2):\n igc: Add support for taprio offloading\n igc: Add support for ETF offloading\n\n drivers/net/ethernet/intel/igc/Makefile | 2 +-\n drivers/net/ethernet/intel/igc/igc.h | 10 +\n drivers/net/ethernet/intel/igc/igc_defines.h | 20 ++\n drivers/net/ethernet/intel/igc/igc_main.c | 183 ++++++++++++++++++-\n drivers/net/ethernet/intel/igc/igc_regs.h | 12 ++\n drivers/net/ethernet/intel/igc/igc_tsn.c | 154 ++++++++++++++++\n 6 files changed, 377 insertions(+), 4 deletions(-)\n create mode 100644 drivers/net/ethernet/intel/igc/igc_tsn.c" }
