This is required because\nit doesn't have the privilege level to issue the admin queue commands, so it acts\nas a proxy PF. So that the user can customize the AVF feature, and use their own\nprogramming language to translate the flow rule management data into ice raw flow,\nthese raw flows then can be executed in PF's sandbox.\n\nAnd the kernel PF driver fully controls the behavior of DCF for security, like only\nthe trusted VF with ID zero can run into DCF mode, and also for being compatible\nwith the common AVF feature, the VF needs to advertise and acquire DCF capability\nfirstly.\n\nv7: Remove the CONFIG_PCI_IOV for function 'ice_aq_sw_rules'.\n\nv6: Rebase with the new commit for ice_switch.c/h.\n\nv5: Update the prefix with 'net-next'.\n\nv4: Mirror commit message update.\n\nv3: Remove the unused function, and control the ice_aq_sw_rules scope by CONFIG_PCI_IOV.\n Capitalize all abbreviations.\n\nv2: Fix the macro ICE_DCF_VFID definition style issue.\n\nHaiyue Wang (5):\n ice: add the virtchnl handler for AdminQ command\n ice: add DCF cap negotiation and state machine\n ice: support to get the VSI mapping\n ice: enable DDP package info querying\n ice: add switch rule management for DCF\n\n drivers/net/ethernet/intel/ice/Makefile | 2 +-\n drivers/net/ethernet/intel/ice/ice.h | 2 +\n .../net/ethernet/intel/ice/ice_adminq_cmd.h | 6 +\n drivers/net/ethernet/intel/ice/ice_dcf.c | 839 ++++++++++++++++++\n drivers/net/ethernet/intel/ice/ice_dcf.h | 91 ++\n drivers/net/ethernet/intel/ice/ice_main.c | 2 +\n drivers/net/ethernet/intel/ice/ice_switch.c | 16 +-\n drivers/net/ethernet/intel/ice/ice_switch.h | 27 +-\n drivers/net/ethernet/intel/ice/ice_type.h | 9 +\n .../net/ethernet/intel/ice/ice_virtchnl_pf.c | 366 ++++++++\n .../net/ethernet/intel/ice/ice_virtchnl_pf.h | 1 +\n include/linux/avf/virtchnl.h | 63 ++\n 12 files changed, 1398 insertions(+), 26 deletions(-)\n create mode 100644 drivers/net/ethernet/intel/ice/ice_dcf.c\n create mode 100644 drivers/net/ethernet/intel/ice/ice_dcf.h" }
