HASH region can only offload exact match\n(maskless) flows and hence the masks must be all set for all match\nitems.\n\nPatch 1 queries firmware for HASH filter support.\n\nPatch 2 updates cxgbe_flow to decide whether to place flows in LE-TCAM\nor HASH region based on supported hardware configuration and masks of\nmatch items.\n\nPatch 3 adds Compressed Local IP (CLIP) region support for offloading\nIPv6 flows in HASH region. Also updates LE-TCAM region to use CLIP for\noffloading IPv6 flows on Chelsio T6 NICs.\n\nPatch 4 adds support for offloading flows to HASH region.\n\nPatch 5 adds support for deleting flows in HASH region.\n\nPatch 6 adds support to query hit and byte counters for offloaded flows\nin HASH region.\n\nPatch 7 adds support to flush filters in HASH region.\n\nPatch 8 adds support to match flows based on physical ingress port.\n\nPatch 9 adds support to redirect packets matching flows to specified\nphysical egress port without sending them to host.\n\nThanks,\nRahul\n\nShagun Agrawal (9):\n net/cxgbe: query firmware for HASH filter resources\n net/cxgbe: validate flows offloaded to HASH region\n net/cxgbe: add Compressed Local IP region\n net/cxgbe: add support to offload flows to HASH region\n net/cxgbe: add support to delete flows in HASH region\n net/cxgbe: add support to query hit counters for flows in HASH region\n net/cxgbe: add support to flush flows in HASH region\n net/cxgbe: add support to match on ingress physical port\n net/cxgbe: add support to redirect packets to egress physical port\n\n drivers/net/cxgbe/Makefile | 1 +\n drivers/net/cxgbe/base/adapter.h | 43 ++\n drivers/net/cxgbe/base/common.h | 10 +\n drivers/net/cxgbe/base/t4_hw.c | 7 +\n drivers/net/cxgbe/base/t4_msg.h | 188 +++++++++\n drivers/net/cxgbe/base/t4_regs.h | 12 +\n drivers/net/cxgbe/base/t4_tcb.h | 26 ++\n drivers/net/cxgbe/base/t4fw_interface.h | 31 ++\n drivers/net/cxgbe/clip_tbl.c | 195 +++++++++\n drivers/net/cxgbe/clip_tbl.h | 31 ++\n drivers/net/cxgbe/cxgbe_compat.h | 12 +\n drivers/net/cxgbe/cxgbe_filter.c | 697 ++++++++++++++++++++++++++++++--\n drivers/net/cxgbe/cxgbe_filter.h | 13 +-\n drivers/net/cxgbe/cxgbe_flow.c | 151 ++++++-\n drivers/net/cxgbe/cxgbe_main.c | 170 +++++++-\n drivers/net/cxgbe/cxgbe_ofld.h | 66 ++-\n 16 files changed, 1614 insertions(+), 39 deletions(-)\n create mode 100644 drivers/net/cxgbe/base/t4_tcb.h\n create mode 100644 drivers/net/cxgbe/clip_tbl.c\n create mode 100644 drivers/net/cxgbe/clip_tbl.h" }
