Chelsio NICs can support wildcard (maskfull) filters\nand exact (maskless) filters. Filters can be created in two regions\navailable on Chelsio NICs. The smaller LE-TCAM region can support both\nmaskfull and maskless filters; whereas, the larger HASH region can\nsupport only maskless filters. This series adds support for LE-TCAM\nregion. Support for HASH region will be added in subsequent series.\n\nThis series adds support for:\n<match item>: IPv4, IPv6, TCP, and UDP.\n<action>: Drop, Queue, and Count.\n\nSupport for more match items and actions will be added in subsequent\nseries.\n\nPatch 1 queries firmware for available filtering resources in the\nunderlying device and adds table to manage these resources.\n\nPatch 2 introduces rte_flow skeleton and implementes validate\noperation.\n\nPatch 3 exports control queue needed for communicating filter\ncreate/delete requests with firmware.\n\nPatch 4 adds firmware API to create filter work requests for\ncreating/deleting filters and implements flow create operation.\n\nPatch 5 adds flow destroy operation.\n\nPatch 6 adds flow query operation to get filter hit and byte counts.\n\nPatch 7 adds flow flush operation to delete all filters under specified\nport.\n\nThanks,\nRahul\n\n\nShagun Agrawal (7):\n net/cxgbe: query firmware for filter resources\n net/cxgbe: parse and validate flows\n net/cxgbe: add control queue to communicate filter requests\n net/cxgbe: implement flow create operation\n net/cxgbe: implement flow destroy operation\n net/cxgbe: implement flow query operation\n net/cxgbe: implement flow flush operation\n\n doc/guides/nics/cxgbe.rst | 1 +\n doc/guides/nics/features/cxgbe.ini | 1 +\n doc/guides/rel_notes/release_18_08.rst | 5 +\n drivers/net/cxgbe/Makefile | 2 +\n drivers/net/cxgbe/base/adapter.h | 63 +++\n drivers/net/cxgbe/base/common.h | 17 +\n drivers/net/cxgbe/base/t4_hw.c | 234 +++++++++++\n drivers/net/cxgbe/base/t4_hw.h | 4 +\n drivers/net/cxgbe/base/t4_msg.h | 22 +\n drivers/net/cxgbe/base/t4_regs.h | 16 +\n drivers/net/cxgbe/base/t4fw_interface.h | 221 ++++++++++\n drivers/net/cxgbe/cxgbe.h | 3 +\n drivers/net/cxgbe/cxgbe_ethdev.c | 5 +\n drivers/net/cxgbe/cxgbe_filter.c | 609 +++++++++++++++++++++++++++\n drivers/net/cxgbe/cxgbe_filter.h | 226 ++++++++++\n drivers/net/cxgbe/cxgbe_flow.c | 702 ++++++++++++++++++++++++++++++++\n drivers/net/cxgbe/cxgbe_flow.h | 42 ++\n drivers/net/cxgbe/cxgbe_main.c | 184 +++++++++\n drivers/net/cxgbe/cxgbe_ofld.h | 27 ++\n drivers/net/cxgbe/sge.c | 197 ++++++++-\n 20 files changed, 2580 insertions(+), 1 deletion(-)\n create mode 100644 drivers/net/cxgbe/cxgbe_filter.c\n create mode 100644 drivers/net/cxgbe/cxgbe_filter.h\n create mode 100644 drivers/net/cxgbe/cxgbe_flow.c\n create mode 100644 drivers/net/cxgbe/cxgbe_flow.h\n create mode 100644 drivers/net/cxgbe/cxgbe_ofld.h" }
