This series contains updates to ice driver and virtchnl header file. The iproute2 and ethtool are evolving to expose the NIC hardware capability. But these available orchestration methods in Linux kernel are limited in their capability to exercise advanced functionality in the hardware, since different vendors may have different data programming method.
Intel Ethernet Adaptive Virtual Function (AVF) is the common hardware interface for SR-IOV, it has the defined message format to talk with the PF. To make good use of the advanced functionality like Switch (Binary Classifier). The ice PF driver introduces a DCF (Device Config Function) mode to extend the AVF feature. The DCF (Device Config Function) method wraps a raw flow admin queue command in a virthcnl message and sends it to the PF to be executed. This is required because it doesn't have the privilege level to issue the admin queue commands, so it acts as a proxy PF. So that the user can customize the AVF feature, and use their own programming language to translate the flow rule management data into ice raw flow, these raw flows then can be executed in PF's sandbox. And the kernel PF driver fully controls the behavior of DCF for security, like only the trusted VF with ID zero can run in DCF mode, and also for being compatible with the common AVF feature, the VF needs to advertise and acquire DCF capability first. The following are changes since commit 94339443686b36d3223bc032b7947267474e2679: net: bridge: notify on vlan tunnel changes done via the old api and are available in the git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/next-queue 100GbE Haiyue Wang (5): ice: add the virtchnl handler for AdminQ command ice: add DCF cap negotiation and state machine ice: support to get the VSI mapping ice: enable DDP package info querying ice: add switch rule management for DCF drivers/net/ethernet/intel/ice/Makefile | 2 +- drivers/net/ethernet/intel/ice/ice.h | 2 + .../net/ethernet/intel/ice/ice_adminq_cmd.h | 6 + drivers/net/ethernet/intel/ice/ice_dcf.c | 833 ++++++++++++++++++ drivers/net/ethernet/intel/ice/ice_dcf.h | 91 ++ drivers/net/ethernet/intel/ice/ice_main.c | 2 + drivers/net/ethernet/intel/ice/ice_switch.c | 16 +- drivers/net/ethernet/intel/ice/ice_switch.h | 27 +- drivers/net/ethernet/intel/ice/ice_type.h | 9 + .../net/ethernet/intel/ice/ice_virtchnl_pf.c | 366 ++++++++ .../net/ethernet/intel/ice/ice_virtchnl_pf.h | 1 + include/linux/avf/virtchnl.h | 63 ++ 12 files changed, 1392 insertions(+), 26 deletions(-) create mode 100644 drivers/net/ethernet/intel/ice/ice_dcf.c create mode 100644 drivers/net/ethernet/intel/ice/ice_dcf.h -- 2.26.2
